gem install fluent-plugin-sumologic_output

Configuration options for fluent.conf are:

• data_type - The type of data that will be sent to Sumo Logic, either logs or metrics (Default is logs )
• endpoint - SumoLogic HTTP Collector URL
• verify_ssl - Verify ssl certificate. (default is true)
• source_category^* - Set _sourceCategory metadata field within SumoLogic (default is nil)
• source_name^* - Set _sourceName metadata field within SumoLogic - overrides source_name_key (default is nil)
• source_name_key - Set as source::path_key's value so that the source_name can be extracted from Fluentd's buffer (default source_name)
• source_host^* - Set _sourceHost metadata field within SumoLogic (default is nil)
• log_format - Format to post logs into Sumo. (default json)
  • text - Logs will appear in SumoLogic in text format (taken from the field specified in log_key)
  • json - Logs will appear in SumoLogic in json format.
  • json_merge - Same as json but merge content of log_key into the top level and strip log_key
• log_key - Used to specify the key when merging json or sending logs in text format (default message)
• open_timeout - Set timeout seconds to wait until connection is opened.
• send_timeout - Timeout for sending to SumoLogic in seconds. Don't modify unless you see HTTPClient::SendTimeoutError in your Fluentd logs. (default 120)
• add_timestamp - Add timestamp (or timestamp_key) field to logs before sending to sumologic (default true)
• timestamp_key - Field name when add_timestamp is on (default timestamp)
• proxy_uri - Add the uri of the proxy environment if present.
• metric_data_format - The format of metrics you will be sending, either graphite or carbon2 or prometheus (Default is graphite )
• disable_cookies - Option to disable cookies on the HTTP Client. (Default is false )

Reading from the JSON formatted log files with in_tail and wildcard filenames:

<source>
  @type tail
  format json
  time_key time
  path /path/to/*.log
  pos_file /path/to/pos/ggcp-app.log.pos
  time_format %Y-%m-%dT%H:%M:%S.%NZ
  tag appa.*
  read_from_head false
</source>

<match appa.**>
 @type sumologic
 endpoint https://collectors.sumologic.com/receiver/v1/http/XXXXXXXXXX
 log_format json
 source_category prod/someapp/logs
 source_name AppA
 open_timeout 10
</match>

Sending metrics to Sumo Logic using in_http:

<source>
  @type http
  port 8888
  bind 0.0.0.0
</source>

<match test.carbon2>
	@type sumologic
	endpoint https://endpoint3.collection.us2.sumologic.com/receiver/v1/http/ZaVnC4dhaV1hYfCAiqSH-PDY6gUOIgZvO60U_-y8SPQfK0Ks-ht7owrbk1AkX_ACp0uUxuLZOCw5QjBg1ndVPZ5TOJCFgNGRtFDoTDuQ2hzs3sn6FlfBSw==
	data_type metrics
	metric_data_format carbon2
	flush_interval 1s
</match>

<match test.graphite>
	@type sumologic
	endpoint https://endpoint3.collection.us2.sumologic.com/receiver/v1/http/ZaVnC4dhaV1hYfCAiqSH-PDY6gUOIgZvO60U_-y8SPQfK0Ks-ht7owrbk1AkX_ACp0uUxuLZOCw5QjBg1ndVPZ5TOJCFgNGRtFDoTDuQ2hzs3sn6FlfBSw==
	data_type metrics
	metric_data_format graphite
	flush_interval 1s
</match>

Assuming following inputs are coming from a log file named /var/log/appa_webserver.log

{"asctime": "2016-12-10 03:56:35+0000", "levelname": "INFO", "name": "appa", "funcName": "do_something", "lineno": 29, "message": "processing something", "source_ip": "123.123.123.123"}

Then output becomes as below within SumoLogic

{
    "timestamp":1481343785000,
    "asctime":"2016-12-10 03:56:35+0000",
    "levelname":"INFO",
    "name":"appa",
    "funcName":"do_something",
    "lineno":29,
    "message":"processing something",
    "source_ip":"123.123.123.123"
}

The plugin supports overriding SumoLogic metadata and log_format parameters within each log message by attaching the field _sumo_metadata to the log message.

NOTE: The _sumo_metadata field will be stripped before posting to SumoLogic.

Example

{
  "name": "appa",
  "source_ip": "123.123.123.123",
  "funcName": "do_something",
  "lineno": 29,
  "asctime": "2016-12-10 03:56:35+0000",
  "message": "processing something",
  "_sumo_metadata": {
    "category": "new_sourceCategory",
    "source": "override_sourceName",
    "host": "new_sourceHost",
    "log_format": "merge_json_log"
  },
  "levelname": "INFO"
}
