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

File (YAML)

tracing:
  datadog:
    localAgentHostPort: 127.0.0.1:8126

File (TOML)

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

CLI

--tracing.datadog.localAgentHostPort=127.0.0.1:8126

debug

Optional, Default=false

Enables Datadog debug.

File (YAML)

tracing:
  datadog:
    debug: true

File (TOML)

[tracing]
  [tracing.datadog]
    debug = true

CLI

--tracing.datadog.debug=true

globalTag

Deprecated in favor of the globalTags option.

Optional, Default=empty

Applies a shared key:value tag on all spans.

File (YAML)

tracing:
  datadog:
    globalTag: sample

File (TOML)

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

File (YAML)

tracing:
  datadog:

File (TOML)

[tracing]
  [tracing.datadog]
    [tracing.datadog.globalTags]
      tag1 = "foo"
      tag2 = "bar"

CLI

--tracing.datadog.globalTags.tag1=foo
--tracing.datadog.globalTags.tag2=bar

prioritySampling
