SignalFx exporter πŸ”—

The SignalFx exporter allows the OpenTelemetry Collector to send metrics and events to SignalFx endpoints. The supported pipeline types are traces, metrics, and logs. See Configure pipelines for more information.


For information on the receiver, see SignalFx receiver.

Get started πŸ”—

By default, the Splunk Distribution of OpenTelemetry Collector includes the SignalFx exporter in the traces, metrics, and logs/signalfx pipelines when deploying in agent mode. See Collector deployment modes for more information.

Sample configurations πŸ”—

The following example shows the default configuration of SignalFx exporter for metrics and events ingest, as well as trace and metrics correlation:

# Metrics + Events
  access_token: "${SPLUNK_ACCESS_TOKEN}"
  api_url: "${SPLUNK_API_URL}"
  ingest_url: "${SPLUNK_INGEST_URL}"
  # Use instead when sending to gateway (http forwarder extension ingress endpoint)
  #api_url: http://${SPLUNK_GATEWAY_URL}:6060
  #ingest_url: http://${SPLUNK_GATEWAY_URL}:9943
  sync_host_metadata: true

When adding the SignalFx exporter, configure both the metrics and logs pipelines. Make sure to also add the SignalFx receiver as in the following example:

      receivers: [signalfx]
      processors: [memory_limiter, batch, resourcedetection]
      exporters: [signalfx]
      receivers: [signalfx]
      processors: [memory_limiter, batch, resourcedetection]
      exporters: [signalfx]

Default metric filters πŸ”—

To prevent unwanted custom metrics, the SignalFx exporter excludes a number of metrics by default. See List of metrics excluded by default for more information.

To override default exclusions and include metrics manually, use the include_metrics option. For example:

      - metric_names: [cpu.interrupt, cpu.user, cpu.system]
      - metric_name: system.cpu.time
          state: [interrupt, user, system]

The following example instructs the exporter to send only the cpu.interrupt metric with a cpu dimension value and both per core and aggregate cpu.idle metrics:

      - metric_name: "cpu.idle"
      - metric_name: "cpu.interrupt"
          cpu: ["*"]

List of metrics excluded by default πŸ”—

Metrics excluded by default by the SignalFx exporter are listed in the default_metrics.go file. The following snippet shows the latest version of the list:

# DefaultExcludeMetricsYaml holds a list of hard coded metrics that's added to the
# exclude list from the config. It includes non-default metrics collected by
# receivers. This list is determined by categorization of metrics in the SignalFx
# Agent. Metrics in the OpenTelemetry convention that have equivalents in the
# SignalFx Agent that are categorized as non-default are also included in this list.

Settings πŸ”—

The following table shows the configuration options for the SignalFx exporter:


Use the access_token_passthrough setting if you’re using a SignalFx receiver with the same setting. Only use the SignalFx receiver with the SignalFx exporter when activating this setting.
