Datadog

To enable the Datadog tracer:

tracing:
  datadog: {}

[tracing]
  [tracing.datadog]

--tracing.datadog=true

Required, Default="127.0.0.1:8126"

Local Agent Host Port instructs the reporter to send spans to the Datadog Agent at this address (host:port).

tracing:
  datadog:
    localAgentHostPort: 127.0.0.1:8126

[tracing]
  [tracing.datadog]
    localAgentHostPort = "127.0.0.1:8126"

--tracing.datadog.localAgentHostPort=127.0.0.1:8126

Optional, Default=false

Enables Datadog debug.

tracing:
  datadog:
    debug: true

[tracing]
  [tracing.datadog]
    debug = true

--tracing.datadog.debug=true

Optional, Default=empty

Applies a shared key:value tag on all spans.

tracing:
  datadog:
    globalTag: sample

[tracing]
  [tracing.datadog]
    globalTag = "sample"

--tracing.datadog.globalTag=sample

Optional, Default=false

Enables priority sampling. When using distributed tracing, this option must be enabled in order to get all the parts of a distributed trace sampled.

tracing:
  datadog:
    prioritySampling: true

[tracing]
  [tracing.datadog]
    prioritySampling = true

--tracing.datadog.prioritySampling=true
