• Minimize difference between Rack transaction duration and total child event durations. (patch 95c37802)

Published on 2024-11-13.

• Add config/appsignal.rb config file support. When a config/appsignal.rb file is present in the app, the Ruby gem will automatically load it when Appsignal.start is called.

  The config/appsignal.rb config file is a replacement for the config/appsignal.yml config file. When both files are present, only the config/appsignal.rb config file is loaded when the configuration file is automatically loaded by AppSignal when the configuration file is automatically loaded by AppSignal.

  Example config/appsignal.rb config file:

  # config/appsignal.rb
  Appsignal.configure do |config|
    config.name = "My app name"
  end

  To configure different option values for environments in the config/appsignal.rb config file, use if-statements:

  # config/appsignal.rb
  Appsignal.configure do |config|
    config.name = "My app name"
    if config.env == "production"
      config.ignore_actions << "My production action"
    end
    if config.env == "staging"
      config.ignore_actions << "My staging action"
    end
  end

  (minor f81248bc, 48d16c7a)

• Add the config/appsignal.rb Ruby config file method to installer, appsignal install. (patch 0d2e2bde)

• Add Appsignal.set_empty_params! helper method. This helper method can be used to unset parameters on a transaction and to prevent the Appsignal instrumentation from adding parameters to a transaction.

  Example usage:

  class PaymentsController < ApplicationController
    def create
      Appsignal.set_empty_params!
  
      # Do things with sensitive parameters
    end
  end

  When Appsignal.add_params is called afterward, the "empty parameters" state is cleared and any AppSignal instrumentation (if called afterward) will also add parameters again.

  # Example: Unset parameters when set
  Appsignal.add_params("abc" => "def")
  # Parameters: { "abc" => "def" }
  Appsignal.set_empty_params!
  # Parameters: {}
  
  # Example: When AppSignal instrumentation sets parameters:
  Appsignal.set_empty_params!
  # Parameters: {}
  # Pseudo example code:
  Appsignal::Instrumentation::SomeLibrary.new.add_params("xyz" => "...")
  # Parameters: {}
  
  # Example: Set parameters after them being unset previously
  Appsignal.set_empty_params!
  # Parameters: {}
  Appsignal.add_params("abc" => "def")
  # Parameters: { "abc" => "def" }

  (patch 20a8050e, 23627cd7)

• Add Appsignal.configure context env? helper method. Check if the loaded environment matches the given environment using the .env?(:env_name) helper.

  Example:

  Appsignal.configure do |config|
    # Symbols work as the argument
    if config.env?(:production)
      config.ignore_actions << "My production action"
    end
  
    # Strings also work as the argument
    if config.env?("staging")
      config.ignore_actions << "My staging action"
    end
  end

  (patch 8b234cae)

• Allow for default attributes to be given when initialising a Logger instance:

  order_logger = Appsignal::Logger.new("app", attributes: { order_id: 123 })

  All log lines reported by this logger will contain the given attribute. Attributes given when reporting the log line will be merged with the default attributes for the logger, with those in the log line taking priority.

  (patch 27e05af6, 8be7c791)

• Read the Hanami Action name without metaprogramming in Hanami 2.2 and newer. This makes our instrumentation more stable whenever something changes in future Hanami releases. (patch c6848504)

• Ignore these Hanami errors by default:

  • Hanami::Router::NotAllowedError (for example: sending a GET request to POST endpoint)
  • Hanami::Router::NotFoundError

  They are usually errors you don't want to be notified about, so we ignore them by default now.

  Customize the ignore_errors config option to continue receiving these errors.

  (patch f1500987)

• Fix request parameter reporting for Hanami 2.2. (patch ca22ed54)

Published on 2024-11-07.

• Add activate_if_environment helper for Appsignal.configure. Avoid having to add conditionals to your configuration file and use the activate_if_environment helper to specify for which environments AppSignal should become active. AppSignal will automatically detect the environment and activate itself it the environment matches one of the listed environments.

  # Before
  Appsignal.configure do |config|
    config.active = Rails.env.production? || Rails.env.staging?
  end
  
  # After
  Appsignal.configure do |config|
    # Activate for one environment
    config.activate_if_environment(:production)
  
    # Activate for multiple environments
    config.activate_if_environment(:production, :staging)
  end

  (patch ff31be88)

• Add a hostname AppSignal tag automatically, based on the OpenTelemetry host.name resource attribute. (Beta only) (patch 35449268)

• Add incident error count metric for enriched OpenTelemetry traces. (Beta only) (patch 35449268)

• Set the app revision config option for Scalingo deploys automatically. If the CONTAINER_VERSION system environment variable is present, it will use used to set the revision config option automatically. Overwrite it's value by configuring the revision config option for your application. (patch 35449268)

• Ignore the Rails healthcheck endpoint (Rails::HealthController#show) by default for Rails apps.

  If the ignore_actions option is set in the config/appsignal.yml file, the default is overwritten. If the APPSIGNAL_IGNORE_ACTIONS environment variable is set, the default is overwritten. When using the Appsignal.configure helper, add more actions to the default like so:

  # config/appsignal.rb
  Appsignal.configure do |config|
    # Add more actions to ignore
    config.ignore_actions << "My action"
  end

  To overwrite the default using the Appsignal.configure helper, do either of the following:

  # config/appsignal.rb
  Appsignal.configure do |config|
    # Overwrite the default value, ignoring all actions ignored by default
    config.ignore_actions = ["My action"]
  
    # To only remove the healtcheck endpoint
    config.ignore_actions.delete("Rails::HealthController#show")
  end

• Internal OpenTelemetry change. (patch 8fb8b93a)

• Fix session data reporting for Action Cable actions. (patch 41642bea)

Published on 2024-09-28.

• Add the reported_by tag to errors reported by the Rails error reporter so the source of the error is easier to identify. (patch ff98ed67)

• Fix no AppSignal internal logs being logged from Capistrano tasks. (patch 089d0325)
• Report all the config options set via Appsignal.config in the DSL config source in the diagnose report. Previously, it would only report the options from the last time Appsignal.configure was called. (patch 27b9aff7)
• Fix 'no implicit conversion of Pathname into String' error when parsing backtrace lines of error causes in Rails apps. (patch b767f269)

Published on 2024-09-26.

• Add support for heartbeat check-ins.

  Use the Appsignal::CheckIn.heartbeat method to send a single heartbeat check-in event from your application. This can be used, for example, in your application's main loop:

  loop do
    Appsignal::CheckIn.heartbeat("job_processor")
    process_job
  end

  Heartbeats are deduplicated and sent asynchronously, without blocking the current thread. Regardless of how often the .heartbeat method is called, at most one heartbeat with the same identifier will be sent every ten seconds.

  Pass continuous: true as the second argument to send heartbeats continuously during the entire lifetime of the current process. This can be used, for example, after your application has finished its boot process:

  def main
    start_app
    Appsignal::CheckIn.heartbeat("my_app", continuous: true)
  end

  (minor 7ae7152c)

• Include the first backtrace line from error causes to show where each cause originated in the interface. (patch 496b035a)

Published on 2024-09-17.

• Add the logger gem as a dependency. This fixes the deprecation warning on Ruby 3.3. (patch 8c1d577e)

• Do not report errors caused by Errno::EPIPE (broken pipe errors) when instrumenting response bodies, to avoid reporting errors that cannot be fixed by the application. (patch 1fdccba4)

• Normalize Rack and Rails UploadedFile objects. Instead of displaying the Ruby class name, it will now show object details like the filename and content type.

  # Before
  #<Rack::Multipart::UploadedFile>
  #<ActionDispatch::Http::UploadedFile>
  
  # After
  #<Rack::Multipart::UploadedFile original_filename: "uploaded_file.txt", content_type: "text/plain">
  #<ActionDispatch::Http::UploadedFile original_filename: "uploaded_file.txt", content_type: "text/plain">

• Fix a ThreadError from being raised on process exit when Appsignal.stop is called from a Signal.trap block, like when Puma shuts down in clustered mode. (patch 32323ded)

Published on 2024-09-12.

• Format the Date and Time objects in a human-friendly way. Previously, dates and times stored in sample data, like session data, would be shown as #<Date> and #<Time>. Now they will show as #<Date: 2024-09-11> and #<Time: 2024-09-12T13:14:15+02:00> (UTC offset may be different for your time objects depending on the server setting). (patch 8f516484)

• Do not include support files in the published versions. This reduces the gem package size. (patch fb729329)

Published on 2024-09-03.

• Add support for Que 2 keyword arguments. Que job arguments will now be reported as the arguments key for positional arguments and keyword_arguments for Ruby keyword arguments. (patch 770bdc06)

Published on 2024-09-02.

• Report Puma low-level errors using the lowlevel_error reporter. This will report errors previously not caught by our instrumentation middleware. (patch 70cc21f4)

• Log a warning when loader defaults are added after AppSignal has already been configured.

  # Bad
  Appsignal.configure # or Appsignal.start
  Appsignal.load(:sinatra)
  
  # Good
  Appsignal.load(:sinatra)
  Appsignal.configure # or Appsignal.start

  (patch 0997dd9c)

• Rename the path and method transaction metadata to request_path and request_method to make it more clear what context this metadata is from. The path and method metadata will continue to be reported until the next major/minor version. (patch fa314b5f)

• Internal change to how OpenTelemetry metrics are sent. (patch e66d1d70)

• Drop support for Puma version 2 and lower. (patch 4fab861c)

• Fix the error log message about our at_exit hook reporting no error on process exit when the process exits without an error. (patch b71f3966)

Published on 2024-08-29.

• Send check-ins concurrently. When calling Appsignal::CheckIn.cron, instead of blocking the current thread while the check-in events are sent, schedule them to be sent in a separate thread.

  When shutting down your application manually, call Appsignal.stop to block until all scheduled check-ins have been sent.

  (patch 46d4ca74)

• Make our Rack BodyWrapper behave like a Rack BodyProxy. If a method doesn't exist on our BodyWrapper class, but it does exist on the body, behave like the Rack BodyProxy and call the method on the wrapped body. (patch e2376305)
• Do not report SignalException errors from our at_exit error reporter. (patch 3ba3ce31)

Published on 2024-08-26.

• Do not report Sidekiq Sidekiq::JobRetry::Handled and Sidekiq::JobRetry::Skip errors. These errors would be reported by our Rails error subscriber. These are an internal Sidekiq errors we do not need to report. (patch e385ee2c)

• Remove the app_path writer in the Appsignal.configure helper. This was deprecated in version 3.x. It is removed now in the next major version.

  Use the root_path keyword argument in the Appsignal.configure helper (Appsignal.configure(:root_path => "...")) to change the AppSignal root path if necessary.

  (patch 6335da6d)

Published on 2024-08-23.

• Do not log a warning for nil data being added as sample data, but silently ignore it because we don't support it. (patch 0a658e5e)
• Fix Rails session data not being reported. (patch 1565c7f0)

Published on 2024-08-23.

• Do not report Sidekiq::JobRetry::Skip errors. These errors would be reported by our Rails error subscriber. This is an internal Sidekiq error we do not need to report. (patch 9ea2d3e8)
• Do not report SystemExit errors from our at_exit error reporter. (patch e9c0cad3)

Published on 2024-08-23.

• Release the final package version. See the pre-release changelog entries for the changes in this version. (major)

• Remove the Transaction.new method Transaction ID argument. The Transaction ID will always be automatically generated. (major bb938a9f)

Published on 2024-08-19.

• Add a helper for parameters sample data to be unset. This is a private method until we stabilize it. (patch e9336363)

Published on 2024-08-19.

• Add an at_exit callback error reporter. By default, AppSignal will now report any unhandled errors that crash the process as long as Appsignal started beforehand.

  require "appsignal"
  
  Appsignal.start
  
  raise "oh no!"
  
  # Will report the error StandardError "oh no!"

  To disable this behavior, set the enable_at_exit_reporter config option to false.

  (major 5124b0e9)

• Report errors from Rails runners. When a Rails runner reports an unhandled error, it will now report the error in the "runner" namespace. (minor 4d6add1d)

• Support adding multiple errors to a transaction.

  Using the Appsignal.report_error helper, you can now report more than one error within the same transaction context, up to a maximum of ten errors per transaction. Each error will be reported as a separate sample in the AppSignal UI.

  Before this change, using Appsignal.report_error or Appsignal.set_error helpers, adding a new error within the same transaction would overwrite the previous one.

  (patch 70ffc00a)

• Change the default Rake task namespace to "rake". Previously, Rake tasks were reported in the "background" namespace. (major 7673b13c)

• Do not start AppSignal when the config file raises an error. Previously, the file source would be ignored. (major 17933fd9)

• Freeze the config after AppSignal has started. Prevent the config from being modified after AppSignal has started to avoid the expectation that modifying the config after starting AppSignal has any effect. (major 46f23f15)

• Do not start Appsignal multiple times if Appsignal.start is called more than once. The configuration can no longer be modified after AppSignal has started. (major fbc2410a)

• The transaction sample data is now merged by default. Previously, the sample data (except for tags) would be overwritten when a sample data helper was called.

  # Old behavior
  Appsignal.set_params("param1" => "value")
  Appsignal.set_params("param2" => "value")
  # The parameters are:
  # { "param2" => "value" }
  
  
  # New behavior
  Appsignal.add_params("param1" => "value")
  Appsignal.add_params("param2" => "value")
  # The parameters are:
  # {  "param1" => "value", "param2" => "value" }

  New helpers have been added:

  • Appsignal.add_tags
  • Appsignal.add_params
  • Appsignal.add_session_data
  • Appsignal.add_headers
  • Appsignal.add_custom_data

  The old named helpers that start with set_ will still work. They will also use the new merging behavior.

  (major 272f18cb)

• Set the Rails config defaults for Appsignal.configure when used in a Rails initializer. Now when using Appsignal.configure in a Rails initializer, the Rails env and root path are set on the AppSignal config as default values and do not need to be manually set. (major 378bbc3e)

• Global transaction metadata helpers now work inside the Appsignal.report_error and Appsignal.send_error callbacks. The transaction yield parameter will continue to work, but we recommend using the global Appsignal.set_* and Appsignal.add_* helpers.

  # Before
  Appsignal.report_error(error) do |transaction|
    transaction.set_namespace("my namespace")
    transaction.set_action("my action")
    transaction.add_tags(:tag_a => "value", :tag_b => "value")
    # etc.
  end
  Appsignal.send_error(error) do |transaction|
    transaction.set_namespace("my namespace")
    transaction.set_action("my action")
    transaction.add_tags(:tag_a => "value", :tag_b => "value")
    # etc.
  end
  
  # After
  Appsignal.report_error(error) do
    Appsignal.set_namespace("my namespace")
    Appsignal.set_action("my action")
    Appsignal.add_tags(:tag_a => "value", :tag_b => "value")
    # etc.
  end
  Appsignal.send_error(error) do
    Appsignal.set_namespace("my namespace")
    Appsignal.set_action("my action")
    Appsignal.add_tags(:tag_a => "value", :tag_b => "value")
    # etc.
  end

  (major 7ca6ce21)

• Include the Rails app config in diagnose report. If AppSignal is configured in a Rails initializer, this config is now included in the diagnose report. (minor 5439d5cb)

• Include the config options from the loaders config defaults and the Appsignal.configure helper in diagnose report. The sources for config option values will include the loaders and Appsignal.configure helper in the output and the JSON report sent to our severs, when opted-in. (patch a7b34110)

• Calculate error rate by transactions with an error, not the number of errors on a transaction. This limits the error rate to a maximum of 100%. (patch da4975cd)

• Remove all deprecated components. Please follow our Ruby gem 4 upgrade guide when upgrading to this version to avoid any errors from calling removed components, methods and helpers. (major f65bee8d)
• Remove the Appsignal.listen_for_error helper. Use manual exception handling using rescue => error with the Appsignal.report_error helper instead. (major 7c232925)
• Remove (private) Appsignal::Transaction::FRONTEND constant. This was previously used for the built-in front-end integration, but this has been absent since version 3 of the Ruby gem. (major c12188e7)
• Remove the Appsignal.config= writer. Use the Appsignal.configure helper to configure AppSignal. (major f4fdf91b)

• Fix an issue where, when setting several errors for the same transaction, error causes from a different error would be shown for an error that has no causes. (patch d54ce8b9)

Published on 2024-08-23.

• Release the final package version. See the pre-release changelog entries for the changes in this version. (patch)

Published on 2024-08-22.

• Ignore Errno::EPIPE errors when instrumenting response bodies. We've noticed this error gets reported when the connection is broken between server and client. This happens in normal scenarios so we'll ignore this error in this scenario to avoid error reports from errors that cannot be resolved. (patch 8ad8a057)

Published on 2024-08-14.

• Remove the HTTP gem's exception handling. Errors from the HTTP gem will no longer always be reported. The error will be reported only when an HTTP request is made in an instrumented context. This gives applications the opportunity to add their own custom exception handling.

  begin
    HTTP.get("https://appsignal.com/error")
  rescue => error
    # Either handle the error or report it to AppSignal
  end

  (minor 2a452ff0)

• Rename heartbeats to cron check-ins. Calls to Appsignal.heartbeat and Appsignal::Heartbeat should be replaced with calls to Appsignal::CheckIn.cron and Appsignal::CheckIn::Cron, for example:

  # Before
  Appsignal.heartbeat("do_something") do
    do_something
  end
  
  # After
  Appsignal::CheckIn.cron("do_something") do
    do_something
  end

  (patch 2f686cd0)

• Calls to Appsignal.heartbeat and Appsignal::Heartbeat will emit a deprecation warning. (patch 2f686cd0)

Published on 2024-08-05.

• Configure AppSignal with the install CLI when no known frameworks is found. Automate the configure step so that this doesn't have to be done manually along with the manual setup for the app. (patch a9c546fa)

• Deprecate the Appsignal.listen_for_error helper. Use a manual error rescue with Appsignal.report_error. This method allows for more customization of the reported error.

  # Before
  Appsignal.listen_for_error do
    raise "some error"
  end
  
  # After
  begin
    raise "some error"
  rescue => error
    Appsignal.report_error(error)
  end

  Read our Exception handling guide for more information.

  (patch 14bd8882)

• Deprecate the Appsignal.configure's app_path writer. Use the Appsignal.configure's root_path keyword argument to configure the path. (patch c79f46c3)

• Fix an error on the Padrino require in the installer CLI. The latest Padrino version will crash the installer on load. Ignore the error when it fails to load. (patch dfe23707)
• Fix the Appsignal.configure path config not being customizable. It's now possible to pass a root_path keyword argument to Appsignal.configure to customize the path from which AppSignal reads the config file, config/appsignal.yml. (patch c79f46c3)

Published on 2024-08-01.

• Improve sanitization of INSERT INTO ... VALUES with multiple groups by removing additional repeated groups.

  This makes the query easier to read, and mitigates an issue where processing many events with slightly distinct queries would cause some event details to de discarded.

  (patch 45a20433)

• Fix issue sanitizing SQL queries containing TRUE and FALSE values in an INSERT INTO ... VALUES clause. (patch 45a20433)

Published on 2024-08-01.

• Fix an issue where, depending on the relative order of the appsignal and view_component dependencies in the Gemfile, the ViewComponent instrumentation would not load. (patch 0f37fa30)

Published on 2024-07-30.

• Fix the application environment being reported as "[]" when no valid environment could be found. (patch cf081253)
• Fix Appsignal.configure call without env argument not reusing the previously configured configuration. (patch 65d5428c)

Published on 2024-07-25.

• Fix the default env and root path for the integrations using loader mechanism. If APPSIGNAL_APP_ENV is set when using Appsignal.load(...), the AppSignal env set in APPSIGNAL_APP_ENV is now leading again. (patch b2d1c7ee)

Published on 2024-07-25.

• Fix Appsignal.monitor_and_stop block passing. It would error with a LocalJumpError. Thanks to @cwaider. (patch 150569ff)

Published on 2024-07-22.

• Add a Rails configuration option to start AppSignal after Rails is initialized. By default, AppSignal will start before the Rails initializers are run. This way it is not possible to configure AppSignal in a Rails initializer using Ruby. To configure AppSignal in a Rails initializer, configure Rails to start AppSignal after it is initialized.

  # config/application.rb
  
  # ...
  
  module MyApp
    class Application < Rails::Application
      # Add this line
      config.appsignal.start_at = :after_initialize
  
      # Other config
    end
  end

  Then, in the initializer:

  # config/initializers/appsignal.rb
  
  Appsignal.configure do |config|
    config.ignore_actions = ["My action"]
  end

  Be aware that when start_at is set to after_initialize, AppSignal will not track any errors that occur when the initializers are run and the app fails to start.

  See our Rails documentation for more information.

  (minor b84a6a36)

• Add a new method of configuring AppSignal: Appsignal.configure. This new method allows apps to configure AppSignal in Ruby.

  # The environment will be auto detected
  Appsignal.configure do |config|
    config.activejob_report_errors = "discard"
    config.sidekiq_report_errors = :discard
    config.ignore_actions = ["My ignored action", "My other ignored action"]
    config.request_headers << "MY_HTTP_HEADER"
    config.send_params = true
    config.enable_host_metrics = false
  end
  
  # Explicitly define which environment to start
  Appsignal.configure(:production) do |config|
    # Some config
  end

  This new method can be used to update config in Ruby. We still recommend to use the config/appsignal.yml file to configure AppSignal whenever possible. Apps that use the Appsignal.config = Appsignal::Config.new(...) way of configuring AppSignal, should be updated to use the new Appsignal.configure method. The Appsignal::Config.new method would overwrite the given "initial config" with the config file's config and config read from environment variables. The Appsignal.configure method is leading. The config file, environment variables and Appsignal.configure methods can all be mixed.

  See our configuration guide for more information.

  (minor ba60fff9)

• Update the Sinatra, Padrino, Grape and Hanami integration setup for applications. Before this change a "appsignal/integrations/sinatra" file would need to be required to load the AppSignal integration for Sinatra. Similar requires exist for other libraries. This has changed to a new integration load mechanism.

  This new load mechanism makes starting AppSignal more predictable when loading multiple integrations, like those for Sinatra, Padrino, Grape and Hanami.

  # Sinatra example
  # Before
  require "appsignal/integrations/sinatra"
  
  # After
  require "appsignal"
  
  Appsignal.load(:sinatra)
  Appsignal.start

  The require "appsignal/integrations/sinatra" will still work, but is deprecated in this release.

  See the documentation for the specific libraries for the latest on how to integrate AppSignal.

  • Grape
  • Hanami
  • Padrino
  • Sinatra

  When using a combination of the libraries listed above, read our integration guide on how to load and configure AppSignal for multiple integrations at once.

  (minor 35fff8cb)

• Disable the AppSignal Rack EventHandler when AppSignal is not active. It would still trigger our instrumentation when AppSignal is not active. This reduces the instrumentation overhead when AppSignal is not active. (patch 03e7c1b2)

• Deprecate the Appsignal.config = Appsignal::Config.new(...) method of configuring AppSignal. See the changelog entry about Appsignal.configure { ... } for the new way to configure AppSignal in Ruby. (minor ba60fff9)
• Deprecate the Hanami integration require: require "appsignal/integrations/hanami". Use the new Appsignal.load(:hanami) method instead. Read our Hanami docs for more information. (patch)
• Deprecate the Padrino integration require: require "appsignal/integrations/padrino". Use the new Appsignal.load(:padrino) method instead. Read our Padrino docs for more information. (patch)
• Deprecate the Sinatra integration require: require "appsignal/integrations/sinatra". Use the new Appsignal.load(:sinatra) method instead. Read our Sinatra docs for more information. (patch)
• Deprecate the Grape integration require: require "appsignal/integrations/grape". Use the new Appsignal.load(:grape) method instead. Read our Grape docs for more information. (patch)

• Fix instrumentation events for response bodies appearing twice. When multiple instrumentation middleware were mounted in an application, it would create duplicate process_response_body.rack events. (patch 24b16517)

Published on 2024-07-15.

• Add Appsignal.monitor and Appsignal.monitor_and_stop instrumentation helpers. These helpers are a replacement for the Appsignal.monitor_transaction and Appsignal.monitor_single_transaction helpers.

  Use these new helpers to create an AppSignal transaction and track any exceptions that occur within the instrumented block. This new helper supports custom namespaces and has a simpler way to set an action name. Use this helper in combination with our other Appsignal.set_* helpers to add more metadata to the transaction.

  # New helper
  Appsignal.monitor(
    :namespace => "my_namespace",
    :action => "MyClass#my_method"
  ) do
    # Track an instrumentation event
    Appsignal.instrument("my_event.my_group") do
      # Some code
    end
  end
  
  # Old helper
  Appsignal.monitor_transaction(
    "process_action.my_group",
    :class_name => "MyClass",
    :action_name => "my_method"
  ) do
    # Some code
  end

  The Appsignal.monitor_and_stop helper can be used in the same scenarios as the Appsignal.monitor_single_transaction helper is used. One-off Ruby scripts that are not part of a long running process.

  Read our instrumentation documentation for more information about using theAppsignal.monitor helper.

  (minor f38f0cff)

• Add Appsignal.set_session_data helper. Set custom session data on the current transaction with the Appsignal.set_session_data helper. Note that this will overwrite any request session data that would be set automatically on the transaction. When this method is called multiple times, it will overwrite the previously set value.

  Appsignal.set_session_data("data1" => "value1", "data2" => "value2")

  (patch 48c76635)

• Add Appsignal.set_headers helper. Set custom request headers on the current transaction with the Appsignal.set_headers helper. Note that this will overwrite any request headers that would be set automatically on the transaction. When this method is called multiple times, it will overwrite the previously set value.

  Appsignal.set_headers("PATH_INFO" => "/some-path", "HTTP_USER_AGENT" => "Firefox")

  (patch 7d82dffd)

• Report request headers for webmachine apps. (patch fcfb7a0d)

• Allow tags to have boolean (true/false) values.

  Appsignal.set_tags("my_tag_is_amazing" => true)
  Appsignal.set_tags("my_tag_is_false" => false)

  (patch 1b8e86cb)

• Optimize Sidekiq job arguments being recorded. Job arguments are only fetched and set when we sample the job transaction, which should decrease our overhead for all jobs we don't sample. (patch 3f957301)

• Deprecate Transaction sample helpers: Transaction#set_sample_data and Transaction#sample_data. Please use one of the other sample data helpers instead. See our sample data guide. (patch 2d2e0e43)

• Deprecate the Appsignal::Transaction#set_http_or_background_queue_start method. Use the Appsignal::Transaction#set_queue_start helper instead. (patch d93e0370)

• Deprecate the Appsignal.without_instrumentation helper. Use the Appsignal.ignore_instrumentation_events helper instead. (patch 7cc3c0e4)

• Deprecate the Appsignal::Transaction::GenericRequest class. Use the Appsignal.set_* helpers to set metadata on the Transaction instead. Read our sample data guide for more information. (patch 1c69d3fd)

• Deprecate the 'ID', 'request', and 'options' arguments for the Transaction.create and Transaction.new methods. To add metadata to the transaction, use the Appsignal.set_* helpers. Read our sample data guide for more information on how to set metadata on transactions.

  # Before
  Appsignal::Transaction.create(
    SecureRandom.uuid,
    "my_namespace",
    Appsignal::Transaction::GenericRequest.new(env) # env is a request env Hash
  )
  
  # After
  Appsignal::Transaction.create("my_namespace")

  (patch 2fc2c617)

• Deprecate the Appsignal.monitor_transaction and Appsignal.monitor_single_transaction helpers. See the entry about the replacement helpers Appsignal.monitor and Appsignal.monitor_and_stop. (patch 470d5813)

Published on 2024-07-08.

• Add our new recommended Rack instrumentation middleware. If an app is using the Appsignal::Rack::GenericInstrumentation middleware, please update it to use Appsignal::Rack::InstrumentationMiddleware instead.

  This new middleware will not report all requests under the "unknown" action if no action name is set. To set an action name, call the Appsignal.set_action helper from the app.

  # config.ru
  
  # Setup AppSignal
  
  use Appsignal::Rack::InstrumentationMiddleware
  
  # Run app

  (minor f2596781)

• Add Rake task performance instrumentation. Configure the enable_rake_performance_instrumentation option to true to enable Rake task instrumentation for both error and performance monitoring. To ignore specific Rake tasks, configure ignore_actions to include the name of the Rake task. (minor 63c9aeed)

• Add instrumentation to Rack responses, including streaming responses. New process_response_body.rack and close_response_body.rack events will be shown in the event timeline. These events show how long it takes to complete responses, depending on the response implementation, and when the response is closed.

  This Sinatra route with a streaming response will be better instrumented, for example:

  get "/stream" do
    stream do |out|
      sleep 1
      out << "1"
      sleep 1
      out << "2"
      sleep 1
      out << "3"
    end
  end

  (minor bd2f037b)

• Add the Appsignal.report_error helper to report errors. If you unsure whether to use the Appsignal.set_error or Appsignal.send_error helpers in what context, use Appsignal.report_error to always report the error. (minor 1502ea14)

• Support nested webmachine apps. If webmachine apps are nested in other AppSignal instrumentation it will now report the webmachine instrumentation as part of the parent transaction, reporting more runtime of the request. (patch 243d20ac)

• Report the response status for Padrino requests as the response_status tag on samples, e.g. 200, 301, 500. This tag is visible on the sample detail page. Report the response status for Padrino requests as the response_status metric.

  (patch 9239c26b)

• Add support for nested Padrino apps. When a Padrino app is nested in another Padrino app, or another framework like Sinatra or Rails, it will now report the entire request. (patch 9239c26b)

• Add Appsignal.set_params helper. Set custom parameters on the current transaction with the Appsignal.set_params helper. Note that this will overwrite any request parameters that would be set automatically on the transaction. When this method is called multiple times, it will overwrite the previously set value.

  Appsignal.set_params("param1" => "value1", "param2" => "value2")

  (patch e8d73e8d)

• Add Appsignal.set_custom_data helper to set custom data on the transaction. Previously, this could only be set with Appsignal::Transaction.current.set_custom_data("custom_data", ...). This helper makes setting the custom data more convenient. (patch 875e4435)

• Add Appsignal.set_tags helper as an alias for Appsignal.tag_request. This is a context independent named alias available on the Transaction class as well. (patch 1502ea14)

• Add a block argument to the Appsignal.set_params and Appsignal::Transaction#set_params helpers. When set_params is called with a block argument, the block is executed when the parameters are stored on the Transaction. This block is only called when the Transaction is sampled. Use this block argument to avoid having to parse parameters for every transaction, to speed things up when the transaction is not sampled.

  Appsignal.set_params do
    # Some slow code to parse parameters
    JSON.parse('{"param1": "value1"}')
  end

  (patch 1502ea14)

• Deprecate the appsignal.action and appsignal.route request env methods to set the transaction action name. Use the Appsignal.set_action helper instead.

  # Before
  env["appsignal.action"] = "POST /my-action"
  env["appsignal.route"] = "POST /my-action"
  
  # After
  Appsignal.set_action("POST /my-action")

  (patch 1e6d0b31)

• Deprecate the Appsignal::Rack::StreamingListener middleware. Use the Appsignal::Rack::InstrumentationMiddleware middleware instead. (patch 57d6fa33)

• Deprecate the Appsignal::Rack::GenericInstrumentation middleware. Use the Appsignal::Rack::InstrumentationMiddleware middleware instead. See also the changelog entry about the InstrumentationMiddleware. (patch 1502ea14)

• Fix issue with AppSignal getting stuck in a boot loop when loading the Padrino integration with: require "appsignal/integrations/padrino" This could happen in nested applications, like a Padrino app in a Rails app. AppSignal will now use the first config AppSignal starts with.

  (patch 10722b60)

• Fix the deprecation warning of Bundler.rubygems.all_specs usage. (patch 1502ea14)

Published on 2024-07-02.

• 0230ab4d patch - Track error response status for web requests. When an unhandled exception reaches the AppSignal EventHandler instrumentation, report the response status as 500 for the response_status tag on the transaction and on the response_status metric.

• b3a80038 patch - Require the AppSignal gem in the Grape integration file. Previously require "appsignal" had to be called before require "appsignal/integrations/grape". This require "appsignal" is no longer required.
• e9aa0603 patch - Report Global VM Lock metrics per process. In addition to the existing hostname tag, add process_name and process_id tags to the gvl_global_timer and gvl_waiting_threads metrics emitted by the GVL probe, allowing these metrics to be tracked in a per-process basis.

• 844aa0af patch - Deprecate Appsignal::Grape::Middleware constant in favor of Appsignal::Rack::GrapeMiddleware constant.

  To fix this deprecation warning, update the usage of Appsignal::Grape::Middleware like this:

  # Grape only apps
  insert_before Grape::Middleware::Error, Appsignal::Rack::GrapeMiddleware
  # or
  use Appsignal::Rack::GrapeMiddleware
  
  # Grape on Rails app
  use Appsignal::Rack::GrapeMiddleware

• 1f648ab4 patch - Deprecate the Appsignal.start_logger method. Remove this method call from apps if it is present. Calling Appsignal.start will now initialize the logger.

• 0bb29809 patch - Fix an issue with invalid request methods raising an error in the GenericInstrumentation middleware when using a request class that throws an error when calling the request_method method, like ActionDispatch::Request.
• 66bb7a60 patch - Support Grape apps that are nested in other apps like Sinatra and Rails, that also include AppSignal middleware for instrumentation.
• a7b056bd patch - Support Hanami version 2.1. On older versions of our Ruby gem it would error on an unknown keyword argument "sessions_enabled".
• 00b7ac6a patch - Fix issue with AppSignal getting stuck in a boot loop when loading the Hanami integration with: require "appsignal/integrations/hanami" This could happen in nested applications, like a Hanami app in a Rails app. It will now use the first config AppSignal starts with.

Published on 2024-06-26.

• Improve instrumentation of Hanami requests by making sure the transaction is always closed. It will also report a response_status tag and metric for Hanami requests.

  (patch e79d4277)

• Instrument the entire Sinatra request. Instrumenting Sinatra apps using require "appsignal/integrations/sinatra" will now report more of the request, if previously other middleware were not instrumented. It will also report the response status with the response_status tag and metric. (patch 15b3390b)

• Fix deprecation warnings about Transacation.params= usage by updating how we record parameters in our instrumentations. (patch b65d6674)
• Fix error reporting for requests with an error that use the AppSignal EventHandler. (patch 0e48f19b)

Published on 2024-06-24.

• 0a253aa1 patch - Fix parameter reporting for Rack and Sinatra apps, especially POST payloads.

Published on 2024-06-21.

• 500b2b4b minor - Report Sidekiq errors when a job is dead/discarded. Configure the new sidekiq_report_errors config option to "discard" to only report errors when the job is not retried further.

• c76952ff patch - Improve instrumentation for mounted Sinatra apps in Rails apps. The sample reported for the Sinatra request will now include the time spent in Rails and its middleware.
• 661b8e08 patch - Support apps that have multiple Appsignal::Rack::EventHandler-s in the middleware stack.
• 7382afa3 patch - Improve support for instrumentation of nested pure Rack and Sinatra apps. It will now report more of the request's duration and events. This also improves support for apps that have multiple Rack GenericInstrumentation or SinatraInstrumentation middlewares.

• 2478eb19 patch - Fix issue with AppSignal getting stuck in a boot loop when loading the Sinatra integration with: require "appsignal/integrations/sinatra" This could happen in nested applications, like a Sinatra app in a Rails app. It will now use the first config AppSignal starts with.

Published on 2024-06-17.

• 5459a021 patch - Report the response status for Rails requests as the response_status tag on samples, e.g. 200, 301, 500. This tag is visible on the sample detail page.

  The response status is also reported as the response_status metric.

Published on 2024-06-17.

• ca53b043 minor - Report the time spent in Rails middleware as part of the request duration. The AppSignal Rack middleware is now higher in the middleware stack and reports more time of the request to give insights in how long other middleware took. This is reported under the new process_request.rack event in the event timeline.

• 37fbae5a patch - Fix ArgumentError being raised on Ruby logger and Rails.logger error calls. This fixes the error from being raised from within the AppSignal Ruby gem. Please do not use this for error reporting. We recommend using our error reporting feature instead to be notified of new errors. Read more on exception handling in Ruby with our Ruby gem.

• 704a7d29 patch - When the minutely probes thread takes more than 60 seconds to run all the registered probes, log an error. This helps find issues with the metrics reported by the probes not being accurately reported for every minute.
• 5f4cc8be patch - Internal agent changes for the Ruby gem.

Published on 2024-05-14.

• bf81e165 patch - Support events emitted by ViewComponent. Rendering of ViewComponent-based components will appear as events in your performance samples' event timeline.

  For AppSignal to instrument ViewComponent events, you must first configure ViewComponent to emit those events:

  # config/application.rb
  module MyRailsApp
    class Application < Rails::Application
      config.view_component.instrumentation_enabled = true
      config.view_component.use_deprecated_instrumentation_name = false
    end
  end

  Thanks to Trae Robrock (@trobrock) for providing a starting point for this implementation!

• ad5c9955 patch - Support Kamal-based deployments. Read the KAMAL_VERSION environment variable, which Kamal exposes within the deployed container, if present, and use it as the application revision if it is not set. This will automatically report deploy markers for applications using Kamal.

• 30bb675f patch - Fix an issue where an error about the AppSignal internal logger is raised when sending a heartbeat.

Published on 2024-05-09.

• 4f12684b patch - Fix LocalJumpError in Active Job instrumentation initialization for Active Job < 7.1.

Published on 2024-05-08.

• 28a36ba1 patch - Add option to activejob_report_errors option to only report errors when a job is discard by Active Job. In the example below the job is retried twice. If it fails with an error twice the job is discarded. If activejob_report_errors is set to discard, you will only get an error reported when the job is discarded. This new discard value only works for Active Job 7.1 and newer.

  class ExampleJob < ActiveJob::Base
    retry_on StandardError, :attempts => 2
  
    # ...
  end

• d6d233de patch - Track Active Job executions per job. When a job is retried the "executions" metadata for Active Job jobs goes up by one for every retry. We now track this as the executions tag on the job sample.

Published on 2024-05-06.

• b6e8ebe2 patch - Fix deprecation warnings for Probes.probes introduced in 3.7.1 for internally registered probes.

Published on 2024-04-29.

• 226a8f51 patch - If the gem can't find a valid log path in the app's log/ directory, it will no longer print the warning more than once.
• 5f97aa29 patch - Stop the minutely probes when Appsignal.stop is called. When Appsignal.stop is called, the probes thread will no longer continue running in the app process.
• ccfa3572 patch - Listen to the APPSIGNAL_HTTP_PROXY environment variable in the extension installer. When APPSIGNAL_HTTP_PROXY is set during gem instal appsignal or bundle install, it will use the proxy specified in the APPSIGNAL_HTTP_PROXY environment variable to download the extension and agent.
• 123c7108 patch - Allow unregistering minutely probes. Use Appsignal::Probes.unregister to unregister probes registered with Appsignal::Probes.register if you do not need a certain probe, including default probes.
• 12305025 patch - Add Appsignal::Probes.register method as the preferred method to register probes. The Appsignal::Probes.probes.register and Appsignal::Minutely.probes.register methods are now deprecated.
• 12305025 patch - Automatically start new probes registered with Appsignal::Probes.register when the gem has already started the probes thread. Previously, the late registered probes would not be run.
• 12305025 patch - Rename the Minutely constant to Probes so that the API is the same between AppSignal integrations. If your apps calls Appsignal::Minutely, please update it to Appsignal::Probes. If your app calls Appsignal::Minutely after this upgrade without the name change, the gem will print a deprecation warning for each time the Appsignal::Minutely is called.
• ee08eed2 patch - Log debug messages when metrics are received for easier debugging.

• a2f4b313 patch - Clear the AppSignal in memory logger, used during the gem start, after the file/STDOUT logger is started. This reduces memory usage of the AppSignal Ruby gem by a tiny bit, and prevent stale logs being logged whenever a process gets forked and starts AppSignal.

Published on 2024-04-22.

• 5b0eb9b2 minor - Heartbeats are currently only available to beta testers. If you are interested in trying it out, send an email to [email protected]!

  ---

  Add heartbeats support. You can send heartbeats directly from your code, to track the execution of certain processes:

  def send_invoices()
    # ... your code here ...
    Appsignal.heartbeat("send_invoices")
  end

  You can pass a block to Appsignal.heartbeat, to report to AppSignal both when the process starts, and when it finishes, allowing you to see the duration of the process:

  def send_invoices()
    Appsignal.heartbeat("send_invoices") do
      # ... your code here ...
    end
  end

  If an exception is raised within the block, the finish event will not be reported to AppSignal, triggering a notification about the missing heartbeat. The exception will bubble outside of the heartbeat block.

• 5fc83cc1 patch - Implement the ignore_logs configuration option, which can also be configured as the APPSIGNAL_IGNORE_LOGS environment variable.

  The value of ignore_logs is a list (comma-separated, when using the environment variable) of log line messages that should be ignored. For example, the value "start" will cause any message containing the word "start" to be ignored. Any log line message containing a value in ignore_logs will not be reported to AppSignal.

  The values can use a small subset of regular expression syntax (specifically, ^, $ and .*) to narrow or expand the scope of lines that should be matched.

  For example, the value "^start$" can be used to ignore any message that is exactly the word "start", but not messages that merely contain it, like "Process failed to start". The value "Task .* succeeded" can be used to ignore messages about task success regardless of the specific task name.

• 8974d201 patch - Add activejob_report_errors config option. When set to "none", ActiveJob jobs will no longer report errors. This can be used in combination with custom exception reporting. By default, the config option has the value "all", which reports all errors.

Published on 2024-02-26.

• 9984156f minor - Add instrumentation for all Rack responses, including streaming responses. New response_body_each.rack, response_body_call.rack and response_body_to_ary.rack events will be shown in the event timeline. This will show how long it takes to complete responses, depending on the response implementation.

  This Sinatra route with a streaming response will be better instrumented, for example:

  get "/stream" do
    stream do |out|
      sleep 1
      out << "1"
      sleep 1
      out << "2"
      sleep 1
      out << "3"
    end
  end

• e7706038 patch - Add histogram support to the OpenTelemetry HTTP server. This allows OpenTelemetry-based instrumentations to report histogram data to AppSignal as distribution metrics.

• 11220302 minor - Breaking change: Normalize CPU metrics for cgroups v1 systems. When we can detect how many CPUs are configured in the container's limits, we will normalize the CPU percentages to a maximum of 100%. This is a breaking change. Triggers for CPU percentages that are configured for a CPU percentage higher than 100% will no longer trigger after this update. Please configure triggers to a percentage with a maximum of 100% CPU percentage.
• 11220302 patch - Support fractional CPUs for cgroups v2 metrics. Previously a CPU count of 0.5 would be interpreted as 1 CPU. Now it will be correctly seen as half a CPU and calculate CPU percentages accordingly.
• 14aefc35 patch - Update bundled trusted root certificates.

• f2abbd6a patch - Fix (sub)traces not being reported in their entirety when the OpenTelemetry exporter sends one trace in multiple export requests. This would be an issue for long running traces, that are exported in several requests.

• c76a3293 patch - Default headers don't contain REQUEST_URI anymore as query params are not filtered. Now REQUEST_PATH is sent instead to avoid any PII filtering.

• 1a863490 patch - Fix disk usage returning a Vec with no entries on Alpine Linux when the df --local command fails.

• bb98744b patch - Deprecate the Appsignal.set_host_gauge and Appsignal.set_process_gauge helper methods in the Ruby gem. These methods would already log deprecation warnings in the appsignal.log file, but now also as a Ruby warning. These methods will be removed in the next major version. These methods already did not report any metrics, and still do not.

• 1a863490 patch - Remove the appsignal_set_host_gauge and appsignal_set_process_gauge extension functions. These functions were already deprecated and did not report any metrics.

• 50708677 patch - Log a warning when no mountpoints are found to report the disk usage metrics. This scenario shouldn't happen (it should log an error, message about skipping a mountpoint or log the disk usage). Log a warning to detect if this issue really occurs.

• a5963f65 patch - Fix Ruby Logger 1.6.0 compatibility

• 2e93182b patch - Fix an error in the diagnose report when reading a file's contents results in an "Invalid seek" error. This could happen when the log path is configured to /dev/stdout, which is not supported.
• ae0b779b patch - Fix logger compatibility with Ruby 3.3

• cee1676f minor - Nested errors are now supported. The error causes are stored as sample data on the transaction so they can be displayed in the UI.

• 2149c064 patch - Filter more disk mountpoints for disk usage and disk IO stats. This helps reduce noise in the host metrics by focussing on more important mountpoints.

  The following mountpoint are ignored. Any mountpoint containing:

  • /etc/hostname
  • /etc/hosts
  • /etc/resolv.conf
  • /snap/
  • /proc/

• 2149c064 patch - - Support disk usage reporting (using df) on Alpine Linux. This host metric would report an error on Alpine Linux.
  • When a disk mountpoint has no inodes usage percentage, skip the mountpoint, and report the inodes information successfully for the inodes that do have an inodes usage percentage.

• 3fe0fa7a patch - Bump agent to eec7f7b

  Updated the probes dependency to 0.5.2. CPU usage is now normalized to the number of CPUs available to the container. This means that a container with 2 CPUs will have its CPU usage reported as 50% when using 1 CPU instead of 100%. This is a breaking change for anyone using the cpu probe.

  If you have CPU triggers set up based on the old behaviour, you might need to update those to these new normalized values to get the same behaviour. Note that this is needed only if the AppSignal integration package you're using includes this change.

• bd15ec20 patch - Bump agent to e8207c1.

  • Add memory_in_percentages and swap_in_percentages host metrics that represents metrics in percentages.
  • Ignore /snap/ disk mountpoints.
  • Fix issue with the open span count in logs being logged as a negative number.
  • Fix agent's TCP server getting stuck when two requests are made within the same fraction of a second.

• 09b45c80 patch - Bump agent to b604345.

  • Add an exponential backoff to the retry sleep time to bind to the StatsD, NGINX and OpenTelemetry exporter ports. This gives the agent a longer time to connect to the ports if they become available within a 4 minute window.
  • Changes to the agent logger:
    • Logs from the agent and extension now use a more consistent format in logs for spans and transactions.
    • Logs that are for more internal use are moved to the trace log level and logs that are useful for debugging most support issues are moved to the debug log level. It should not be necessary to use log level 'trace' as often anymore. The 'debug' log level should be enough.
  • Add running_in_container to agent diagnose report, to be used primarily by the Python package as a way to detect if an app's host is a container or not.

• 1945d613 patch - Bump agent to 1dd2a18.

  • When adding an SQL body attribute via the extension, instead of truncating the body first and sanitising it later, sanitise it first and truncate it later. This prevents an issue where queries containing very big values result in truncated sanitisations.

• c8698dca patch - Fix a deprecation warning for Sidekiq 7.1.6+ when an error is reported to AppSignal. (Thanks @bdewater-thatch!)
• 1c606c6a patch - Fix an internal error when some Redis info keys we're expecting are missing. This will fix the Sidekiq dashboard showing much less data than we can report when Redis is configured to not report all the data points we expect. You'll still miss out of metrics like used memory, but miss less data than before.

• 29970d93 patch - Events from dry-monitor are now supported. There's also native support for rom-sql instrumentation events if they're configured.
• 27656744 patch - Support Rails 7.1 ActiveSupport Notifications handler.

• 6932bb3f patch - Add configuration load modifiers to diagnose report. Track if the APPSIGNAL_INACTIVE_ON_CONFIG_FILE_ERROR environment variable was set.

• 441de353 patch - Add an option to not start AppSignal on config file errors. When the config/appsignal.yml file raises an error (due to ERB syntax issues or ERB errors), it will currently ignore the config file and try to make a configuration work from the other config sources (default, auto detection and system environment variables). This can cause unexpected behavior, because the config from the config file is not part of the loaded config.

  In future versions of the Ruby gem, AppSignal will not start when the config file contains an error. To opt-in to this new behavior, set the APPSIGNAL_INACTIVE_ON_CONFIG_FILE_ERROR system environment variable to either 1 or true.

• a42da92b patch - Log an error when sample data is of an invalid type. Accepted types are Array and Hash. If any other types are given, it will log an error to the appsignal.log file.

  • Increase short data truncation from 2000 to 10000 characters.

• 61e093b8 patch - Bump agent to 6bec691.

  • Upgrade sql_lexer to v0.9.5. It adds sanitization support for the THEN and ELSE logical operators.

• d048c778 patch - Allow passing custom data using the appsignal context via the Rails error reporter:

  custom_data = { :hash => { :one => 1, :two => 2 }, :array => [1, 2] }
  Rails.error.handle(:context => { :appsignal => { :custom_data => custom_data } }) do
    raise "Test"
  end

• 5ddde58b patch - Allow configuration of the agent's TCP and UDP servers using the bind_address config option. This is by default set to 127.0.0.1, which only makes it accessible from the same host. If you want it to be accessible from other machines, use 0.0.0.0 or a specific IP address.
• 74583d26 patch - Report total CPU usage host metric for VMs. This change adds another state tag value on the cpu metric called total_usage, which reports the VM's total CPU usage in percentages.

• 46735abb patch - Use RENDER_GIT_COMMIT environment variable as revision if no revision is specified.

• 86856aae patch - Bump agent to 32590eb.

  • Only ignore disk metrics that start with "loop", not all mounted disks that end with a number to report metrics for more disks.

• 85c155a0 patch - When sanitizing an array or hash, replace recursively nested values with a placeholder string. This fixes a SystemStackError issue when sanitising arrays and hashes.

• e5e79d9a patch - Add filter_metadata config option to filter metadata set on Transactions set by default. Metadata like path, (request) method, request_id, hostname, etc. This can be useful if there's PII or other sensitive data in any of the app's metadata.

• 5a4797c8 patch - Fix Sinatra request custom request parameters method. If the Sinatra option params_method is set, a different method than params will be called on the request object to fetch the request parameters. This can be used to add custom filtering to parameters recorded by AppSignal.

• 9cdee8aa patch - Log error when the argument type of the breadcrumb metadata is invalid. This metadata argument should be a Hash, and other values are not supported. More information can be found in the Ruby gem breadcrumb documentation.

  Appsignal.add_breadcrumb(
    "breadcrumb category",
    "breadcrumb action",
    "some message",
    { :metadata_key => "some value" } # This needs to be a Hash object
  )

• 17500724 patch - Fixed a bug that prevented log messages from getting to AppSignal when using the convenience methods as in:

  Rails.logger.warn("Warning message")

• 8e54a894 patch - Allow configuration of the agent's StatsD server port through the statsd_port option.

• b9a8effe patch - Update bundled trusted root certificates.

• d03735c7 patch - Bump agent to fd8ee9e.

  • Rely on APPSIGNAL_RUNNING_IN_CONTAINER config option value before other environment factors to determine if the app is running in a container.
  • Fix container detection for hosts running Docker itself.
  • Add APPSIGNAL_STATSD_PORT config option.

  • Rename internal _APPSIGNAL_ENVIRONMENT variable to _APPSIGNAL_APP_ENV to be consistent with the public version.

• 4cd1601e patch - Do not run minutely probes on Rails console

• 77ce4e39 patch - Add Rails error reporter support. Errors reported using Rails.error.handle are tracked as separate errors in AppSignal. We rely on our other Rails instrumentation to report the errors reported with Rails.error.record.

  The error is reported under the same controller/job name, on a best effort basis. It may not be 100% accurate. If Rails.error.handle is called within a Rails controller or Active Job job, it will copy the AppSignal transaction namespace, action name and tags from the current transaction to the transaction for the Rails.error.handle reported error. If you call Appsignal.set_namespace, Appsignal.set_action or Appsignal.tag_request after Rails.error.handle, those changes will not be reflected up in the already reported error.

  It is also possible to customize the AppSignal namespace and action name for the reported error using the appsignal context:

  Rails.error.handle(:context => { :appsignal => { :namespace => "context", :action => "ContextAction" } }) do
    raise "Test"
  end

  All other key-values are reported as tags:

  Rails.error.handle(:context => { :tag_key => "tag value" }) do
    raise "Test"
  end

  Integration with the Rails error reporter is enabled by default. Disable this feature by setting the enable_rails_error_reporter config option to false.

• b4f58afd patch - Support Sidekiq in Rails error reporter. Track errors reported using Rails.error.handle in Sidekiq jobs, in the correct action. Previously it would report no action name for the incident, now it will use the worker name by default.

• e0332791 patch - Set the AppSignal transaction namespace, action name and some tags, before Active Job jobs are performed. This allows us to check what the namespace, action name and some tags are during the instrumentation itself.
• 4a40699a patch - The AppSignal gem requires Ruby 3 or higher to run. Remove unnecessary Ruby version checks that query Ruby 2.7 or lower.
• da7d1c76 patch - Internal refactor of Ruby code due to RuboCop upgrade. Use the public prepend method to prepend AppSignal instrumentation modules.

• 009d533f patch - Fix a bug when using ActiveSupport::TaggedLogging calling the silence method.

• a6db61b9 patch - Fixed an error when using our Logging feature with Ruby's default logger formatter.

• 2fc6ba85 patch - Support "warning" value for log_level config option. This option was documented, but wasn't accepted and fell back on the "info" log level if used. Now it works to configure it to the "warn"/"warning" log level.
• c04f7783 patch - Add global VM lock metrics. If the gvltools library is installed, AppSignal for Ruby will report metrics on the global VM lock and the number of waiting threads in your application.

• a815b298 patch - Support cgroups v2. Used by newer Docker engines to report host metrics. Upgrade if you receive no host metrics for Docker containers.

• 8e67159e patch - Configure AppSignal with the RACK_ENV or RAILS_ENV environment variable in diagnose CLI, if present. Makes it easier to run the diagnose CLI in production, without having to always specify the environment with the --environment CLI option.
• a815b298 patch - Allow transaction events to have a duration up to 48 hours before being discarded.

• a815b298 patch - Remove trailing comments in SQL queries, ensuring queries are grouped consistently.

• b2f872bc patch - Fix the T_DATA warning originating from the AppSignal C extension on Ruby 3.2.

• d1b960f0 patch - Reduce our dependency on YAML during installation. Instead of a YAML file with details about the extension download location, use a pure Ruby file. This is a partial fix for the installation issue involving psych version 5.

• e1e598ae patch - Skip the .gemrc config during installation if it raises an error loading it. This can be caused when the psych gem version 5 is installed on Ruby < 3.2. Use the HTTP_PROXY environment variable instead to configure the HTTP proxy that should be used during installation.

• 7f62ada8 patch - Track the Operating System release/distro in the diagnose report. This helps us with debugging what exact version of Linux an app is running on, for example.

• 1443e05f patch - Attempt to load C extension from lib/ directory. Fixes an issue where JRuby would fail to load the extension from the ext/ directory, as the directory is cleaned after installation when using RubyGems 3.4.0.

• e4314b5b minor - Hanami 2 is now supported. Requests will now appear as performance measurements.

• 2b1964d9 patch - Track new Ruby 3.2 VM cache metrics. In Ruby 3.2 the class_serial and global_constant_state metrics are no longer reported for the "Ruby (VM) metrics" magic dashboard, because Ruby 3.2 removed these metrics. Instead we will now report the new constant_cache_invalidations and constant_cache_misses metrics reported by Ruby 3.2.
• 6804e898 patch - Use log formatter if set in logger

• 5e87aa34 patch - Support the http.rb gem's URI argument using objects with the #to_s method. A Ruby URI object is no longer required.

• 199d05c0 minor - Support the http.rb gem. Any outgoing requests will be tracked as events on the incident event timeline. This instrumentation is activated automatically, but can be disable by setting the instrumentation_http_rb option to false.
• 9bcd107d minor - Support log collection from Ruby apps using the new AppSignal Logging feature. Learn more about AppSignal's Logging on our docs.

• a03b7246 patch - Support Sidekiq 7 in the Sidekiq minutely probe. It will now report metrics to Sidekiq magic dashboard for Sidekiq version 7 and newer.

  • Fix http proxy config option parsing for port 80.
  • Fix the return value for appsignal_import_opentelemetry_span extension function in appsignal.h.

• feb60fb8 patch - Fix NoMethodError for AppSignal Puma plugin for Puma 6. Puma 5 is also still supported.

• ffe49cfe patch - Support temporarily disabling GC profiling without reporting inaccurate gc_time metric durations. The MRI probe's gc_time will not report any value when the GC::Profiler.enabled? returns false.

• af7e666c patch - Listen if the Ruby Garbage Collection profiler is enabled and collect how long the GC is running for the Ruby VM magic dashboard. An app will need to call GC::Profiler.enable to enable the GC profiler. Do not enable this in production environments, or at least not for long, because this can negatively impact performance of apps.

• b3a163be patch - Fix the MRI probe using the Garbage Collection profiler instead of the NilProfiler when garbage collection instrumentation is not enabled for MRI probe. This caused unnecessary overhead.

• 811a1082 patch - Add the Transaction.current? helper to determine if any Transaction is currently active or not. AppSignal NilTransactions are not considered active transactions.

• dc50d889 patch - Rename the (so far privately reported) gc_total_time metric to gc_time. It no longer reports the total time of Garbage Collection measured, but only the time between two (minutely) measurements.

• 7cfed987 patch - Fix error on unknown HTTP request method. When a request is made with an unknown request method, triggering and ActionController::UnknownHttpMethod, it will no longer break the AppSignal instrumentation but omit the request method in the sample data.

• 1b95bb4c patch - Report Garbage Collection total time metric as the delta between measurements. This reports a more user friendly metric that doesn't always goes up until the app restarts or gets a new deploy. This metric is reported 0 by default without GC::Profiler.enable having been called.

• 61a78fb0 patch - Bump agent to 06391fb

  • Accept "warning" value for the log_level config option.
  • Add aarch64 Linux musl build.
  • Improve debug logging from the extension.
  • Fix high CPU issue for appsignal-agent when nothing could be read from the socket.

• e225c798 patch - Report all Ruby VM metrics as gauges. We previously reported some metrics as distributions, but all fields for those distributions would report the same values.

• 31fd19c6 patch - Add hostname tag for Ruby VM metrics. This allows us to graph every host separately and multiple hosts won't overwrite each other metrics.

• d10c3f32 minor - Add tracking of thread counts, garbage collection runs, heap slots and other garbage collection stats to the default MRI probe. These metrics will be shown in AppSignal.com in a new Ruby VM Magic Dashboard.

• 114fe4f9 patch - Bump agent to v-d573c9b

  • Display unsupported OpenTelemetry spans in limited form.
  • Clean up payload storage before sending. Should fix issues with locally queued payloads blocking data from being sent.
  • Add appsignal_create_opentelemetry_span function to create spans for further modification, rather than only import them.

• dd803449 patch - Report gauge delta value for allocated objects. This reports a more user friendly metric we can graph with a more stable continuous value in apps with stable memory allocation.

• 547f925e patch - Report gauge delta value for Garbage Collection counts. This reports a more user friendly metric that doesn't always goes up until the app restarts or gets a new deploy.

• e555a81a patch - Fix FFI function calls missing arguments for appsignal_free_transaction and appsignal_free_data extension functions. This fixes a high CPU issue when these function calls would be retried indefinitely.

• 7032dc4b patch - Use Dir.pwd to determine the current directory in the Capistrano 3 integration. It previously relied on ENV["pwd"] which returned nil in some scenarios.

• 56ec42ae patch - Remove Moped support as it is no longer the official Ruby Mongo driver and it's been unmaintained for 7 years.

• 991ca18d patch - Fix runtime errors on YAML load with older psych versions (< 4) used in combination with newer Ruby version (3.x).

• 399cf790 patch - Sanitize ActiveRecord::RecordNotUnique error messages to not include any database values that is not unique in the database. This ensures no personal information is sent to AppSignal through error messages from this error.

• 964861f7 patch - Bump agent to v-f57e6cb

  • Enable process metrics on Heroku and Dokku

• d73905d3 patch - Fix sanitized values wrapped in Arrays. When a value like [{ "foo" => "bar" }] was sanitized it would be stored as { "foo" => "?" }, omitting the parent value's Array square brackets. Now values will appear with the same structure as they were originally sanitized. This only applies to certain integrations like MongoDB, moped and ElasticSearch.
• 096d3cdf patch - Fix the ActiveJob default_queue_name config option issue being reset to "default". When ActiveJob default_queue_name was set in a Rails initializer it would reset on load to default. Now the default_queue_name can be set in an initializer as well.

• 9762e79d patch - Bump agent to v-bbc830a

  • Support batched statsd messages
  • Set start times for spans with traceparents
  • Check duration in transactions for negative and too high value

• 548dd6f4 patch - Add config override source. Track final decisions made by the Ruby gem in the configuration in the override config source. This will help us track new config options which are being set by their deprecated predecessors in the diagnose report.

• 3f503ade patch - Remove internal Appsignal.extensions system. It was unused.

• f19d9dcc patch - The MongoDB query sanitization now shows all the attributes in the query at all levels. Only the actual values are filtered with a ? character. Less MongoDB queries are now marked as N+1 queries when they weren't the exact same query. This increases the number of unique events AppSignal tracks for MongoDB queries.

• 35bd83b8 patch - Add send_session_data option to configure if session data is automatically included transactions. By default this is turned on. It can be disabled by configuring send_session_data to false.

• 35bd83b8 patch - Deprecate skip_session_data option in favor of the newly introduced send_session_data option. If it is configured it will print a warning on AppSignal load, but will also retain its functionality until the config option is fully removed in the next major release.
• e51a8fb6 patch - Warn about the deprecated working_dir_path option from all config sources. It previously only printed a warning when it was configured in the config/appsignal.yml file, but now also prints the warning if it's set via the Config class initialize options and environment variables. Please use the working_directory_path option instead.

• c9000eee patch - Fix reported Ruby version in diagnose report. It would report only the first major release of the series, e.g. 2.6.0 for 2.6.1.

• 2587eae3 patch - Store the extension install report as JSON, instead of YAML. Reduces internal complexity.

• 243c1ed4 patch - Improve compatibility with the sequel-rails gem by tracking the performed SQL query in instrumentation events.

• d7bfcdf1 patch - Add Ruby 3.1.0 support. There was an issue with YAML.load arguments when parsing the appsignal.yml config file.

• f9d57752 patch - Use the log_level option for the Ruby gem logger. Previously it only configured the extension and agent loggers. Also fixes the debug and transaction_debug_mode option if no log_level is configured by the app.

• fe226e99 patch - Add experimental Span API. This is not loaded by default and we do not recommend using it yet.

• 84b1ba18 patch - Add "log_level" config option. This new option allows you to define the kind of messages AppSignal's will log and up. The "debug" option will log all "debug", "info", "warning" and "error" log messages. The default value is: "info"

  The allowed values are:

  • error
  • warning
  • info
  • debug

• 6b2ecca2 patch - Clean up index values in error messages from PG index violation errors.

• 25bde454 patch - Order the config options alphabetically in diagnose report output.

• fe226e99 patch - Use the filter_parameters and filter_session_data options to filter out specific parameter keys or session data keys for the experimental Span API. Previously only the (undocumented) filter_data_keys config option was available to filter out all kinds of app data.

• fe226e99 patch - Standardize diagnose validation failure message. Explain the diagnose request failed and why.

• fe226e99 patch - Bump agent to v-5b63505

  • Only filter parameters with the filter_parameters config option.
  • Only filter session data with the filter_session_data config option.

• 84b1ba18 patch - Deprecate "debug" and "transaction_debug_mode" config options in favor of the new "log_level" config option.

• b40b3b4f patch - Print String values in the diagnose report surrounded by quotes. Makes it more clear that it's a String value and not a label we print.

• fd6faf16 patch - Bump agent to 09308fb

  • Update sql_lexer dependency with support for reversed operators in queries.
  • Add debug level logging to custom metrics in transaction_debug_mode.

  • Support JSON PostgreSQL operator in sql_lexer.
  • Do not strip comments from SQL queries.

• 8d7b80ea patch - Add configuration option for the AppSignal agent StatsD server. This is on by default, but you can disable it with enable_statsd: false.

• 5c202185 patch - Bump agent to v-0318770.

  • Improve Dokku platform detection. Do not disable host metrics on Dokku.
  • Report CPU steal metric.

• 44dd4bdc patch - Check Rails.backtrace_cleaner method before calling the method. This prevents a NoMethodError from being raised in some edge cases.

• 5f94712d patch - Add the APPSIGNAL_BUILD_FOR_LINUX_ARM flag to allow users to enable the experimental Linux ARM build for 64-bit hosts. Usage: export APPSIGNAL_BUILD_FOR_LINUX_ARM=1 bundle install. Please be aware this is an experimental build. Please report any issue you may encounter at our support email.

• 27f9b178 patch - Bump agent to 6caf6d0. Replaces curl HTTP client and includes various other maintenance updates.

• 665d883a patch - Improve Puma plugin stats collection. Instead of starting the AppSignal gem in the main process we send the stats to the AppSignal agent directly using StatsD. This should improve compatibility with phased restarts. If you use prune_bundler, you will need to add AppSignal to the extra extra_runtime_dependencies list.

  # config/puma.rb
  plugin :appsignal
  extra_runtime_dependencies ["appsignal"]
  

• d354d79b patch - Add Excon integration. Track requests and responses from the Excon gem.
• 4c32e818 patch - Support Redis eval statements better by showing the actual script that was performed. Instead of showing eval ? ? ? (for a script with 2 arguments), show <script> ? ?, where <script> is whatever script was sent to Redis.new.eval("<script>").

• 4bddac36 patch - Skip empty HTTP proxy config. When any of the HTTP proxy config returns an empty string, skip this config. This fixes installation issues where an empty String is used as a HTTP proxy, causing a RuntimeError upon installation.

• 6338e822 patch - Drop logger level to debug. Reduce the output on the "info" level and only show these messages in debug mode. This should reduce the noise for users running AppSignal with the STDOUT logger, such as is the default on Heroku.
