v1.107.0

Released at 2024-11-29

Update note 1: cmd-line flags -datasource.lookback, datasource.queryTimeAlignment and remoteRead.ignoreRestoreErrors on vmalert have been removed. Those flags were all deprecated before v1.101.0.

• FEATURE: vmalert: revert the default value of -remoteWrite.maxQueueSize from 1_000_000 to 100_000. It was bumped in v1.104.0, which increases memory usage and is not needed for most setups. See this issue.

• FEATURE: vmui: add Raw Query tab for displaying raw data. See this issue.

• FEATURE: vmui: add support for template alias in predefined panels. This allows creating more readable metric names in the legend using constructions like {{label_name}}, where label_name is the name of the label. See this commit

• FEATURE: stream aggregation: add ignore_first_sample_interval param to aggregation config. It allows users to control the time interval when aggregation skips sending aggregated samples to avoid unexpected spikes in values. By default, this interval is set to x2 of staleness_interval. The new setting is applicable only to total, total_prometheus, increase, increase_prometheus and histogram_bucket outputs. See this issue for details. Thanks to @iyuroch for the pull request.

• FEATURE: vmauth: add dump_request_on_errors bool setting to auth config for debugging HTTP requests that missed routing rules. This should improve debugability of vmauth settings.

• FEATURE: vmauth: add real_ip_header setting to ip_filters and corresponding global flag httpRealIPHeader. It allows vmauth obtain client IP from HTTP headers for filtering. See this issue for details.

• FEATURE: vmauth: expose new metrics vmauth_user_ip_denies_total, vmauth_global_ip_denies_total and vmauth_unauthorized_user_ip_denies_total for ip_filters. See this issue for details.

• FEATURE: vmauth: add dryRun flag to validate configuration. See this issue for details.

• FEATURE: vmauth: add removeXFFHTTPHeaderValue flag to remove content of X-Forwarded-For HTTP Header before proxy it to the backend. See this issue for details.

• BUGFIX: vmagent: properly parse multitenant token value for multitenant endpoints. See this issue.

• BUGFIX: vmagent: Properly return 200 OK HTTP status code when importing data via Pushgateway protocol using multitenant URL format. See this issue and this pull request.

• BUGFIX: vmagent: Properly set TCP connection timeout for Kubernetes API server connection for metric scrapping with kubernetes_sd_configs. See this issue.

• BUGFIX: vmagent: fix the resource_group filter for Azure service discovery on virtual machine scale sets. Previously, this filter did not apply to virtual machine scale sets, causing all virtual machines to be discovered. See this issue.

• BUGFIX: vmauth: properly init ip_filters for unauthorized_user config section. Previously it was ignored and vmauth didn't apply ip_filter for unauthorized access.

• BUGFIX: vmsingle, vmselect in VictoriaMetrics cluster: properly return result for binary operation ^ aka pow at query requests for NaN values. See this issue for details.

• BUGFIX: vmui: fix rendering of isolated data points on the graph that are not connected to other points.

• BUGFIX: vmui: fix for showLegend and alias flags in predefined panels. See this issue

• BUGFIX: vmalert: improve the correctness of alert state restoration. Previously, it could result in false-positive alerts if alert was resolved shortly before vmalert restart.

• BUGFIX: vmalert-tool: exit immediately with error message if no test file is found under specified -files.

• BUGFIX: vmalert-tool: print an error message if no rule group is found in rule_files.

• BUGFIX: vmselect in VictoriaMetrics cluster: Properly handle multitenant query request errors and correctly perform search for available tenants. See this issue for details. This is follow-up after v1.106.1 release changes.

• BUGFIX: vmselect in VictoriaMetrics cluster: properly set multitenant cache expiration duration with search.tenantCacheExpireDuration. Previously flag always used default value.
