Sumo Logic Exporter

Stability level: Beta

This exporter supports sending logs and metrics data to Sumo Logic.

We strongly recommend to use this exporter with sumologicextension.

Configuration is specified via the yaml in the following structure:

exporters:
  # ...
  sumologic:
    # unique URL generated for your HTTP Source, this is the address to send data to
    # deprecated, please use sumologicextension to manage your endpoints
    # if sumologicextension is not being used, the endpoint is required
    endpoint: <HTTP_Source_URL>
    # Compression encoding format, empty string means no compression, default = gzip
    compress_encoding: {gzip, deflate, ""}
    # max HTTP request body size in bytes before compression (if applied),
    # NOTE: this limit does not apply to data sent in otlp format,
    #   to limit size of otlp requests, please use the batch processor:
    #   https://github.com/open-telemetry/opentelemetry-collector/tree/v0.71.0/processor/batchprocessor
    # default = 1_048_576 (1MB)
    max_request_body_size: <max_request_body_size>

    # format to use when sending logs to Sumo Logic, default = otlp,
    # NOTE: only `otlp` is supported when used with sumologicextension
    log_format: {json, text, otlp}

    # format to use when sending metrics to Sumo Logic, default = otlp,
    # NOTE: only `otlp` is supported when used with sumologicextension
    metric_format: {otlp, prometheus}

    # format to use when sending traces to Sumo Logic,
    # currently only otlp is supported
    trace_format: {otlp}

    # timeout is the timeout for every attempt to send data to the backend,
    # maximum connection timeout is 55s, default = 5s
    timeout: <timeout>

    # defines if timestamp for logs should be set to 0,
    # it indicates that backend will extract timestamp from logs,
    # this option affects OTLP format only
    # default = true
    clear_logs_timestamp: {true, false}

    # name of resource attribute which should be dropped for records
    # this is for attribute used by routing processor
    # other attributes should be removed by processors in pipelines before
    # This is workaround for the following issue:
    # https://github.com/open-telemetry/opentelemetry-collector-contrib/issues/7407
    # default = ``
    routing_atttribute_to_drop: <routing_atttribute_to_drop>

    json_logs:
      # defines which key will be used to attach the log body at.
      # This option affects JSON log format only.
      # By default this is "log".
      log_key: <log>
      # defines whether to include a timestamp field when sending
      # JSON logs, which would contain UNIX epoch timestamp in milliseconds.
      # This option affects JSON log format only.
      # default = true.
      add_timestamp: {true, false}
      # when add_timestamp is set to true then this key defines what is the name
      # of the timestamp key.
      # default = "timestamp".
      timestamp_key: <timestamp_key>
      # When flatten_body is set to true and log is a map,
      # log's body is going to be flattened and `log_key` won't be used
      # default = false
      flatten_body: {true, false}

    # instructs sumologicexporter to use an edpoint automatically generated by
    # sumologicextension;
    # to use direct endpoint, set it `auth` to `null` and set the endpoint configuration
    # option;
    # see sumologicextension documentation for details
    # default = sumologic
    auth:
      authenticator: <sumologicextension_name>

    # for below described queueing and retry related configuration please refer to:
    # https://github.com/open-telemetry/opentelemetry-collector/blob/main/exporter/exporterhelper/README.md#configuration

    retry_on_failure:
      # default = true
      enabled: {true, false}
      # time to wait after the first failure before retrying;
      # ignored if enabled is false, default = 5s
      initial_interval: <initial_interval>
      # is the upper bound on backoff; ignored if enabled is false, default = 30s
      max_interval: <max_interval>
      # is the maximum amount of time spent trying to send a batch;
      # ignored if enabled is false, default = 120s
      max_elapsed_time: <max_elapsed_time>

    sending_queue:
      # default = false
      enabled: {true, false}
      # number of consumers that dequeue batches; ignored if enabled is false,
      # default = 10
      num_consumers: <num_consumers>
      # when set, enables persistence and uses the component specified as a storage extension for the persistent queue
      # make sure to configure and add a `file_storage` extension in `service.extensions`.
      # default = None
      storage: <storage_name>
      # maximum number of batches kept in memory before data;
      # ignored if enabled is false, default = 5000
      #
      # user should calculate this as num_seconds * requests_per_second where:
      # num_seconds is the number of seconds to buffer in case of a backend outage,
      # requests_per_second is the average number of requests per seconds.
      queue_size: <queue_size>

Metrics

The Sumo Logic Exporter exposes the following metrics:

  • otelcol_exporter_requests_bytes (counter) - total size of HTTP requests (in bytes)
  • otelcol_exporter_requests_duration (counter) - duration of HTTP requests (in milliseconds)
  • otelcol_exporter_requests_records (counter) - total size of HTTP requests (in number of records)
  • otelcol_exporter_requests_sent (counter) - number of HTTP requests

All of the above metrics have the following dimensions:

  • endpoint - endpoint address
  • exporter - exporter name
  • pipeline - pipeline name (logs, metrics or traces)
  • status_code - HTTP response status code (0 in case of error)
