To enable the Datadog tracer:

File (YAML)

tracing:
  datadog: {}

File (TOML)

[tracing]
  [tracing.datadog]

CLI

--tracing.datadog=true

localAgentHostPort

Optional, Default="localhost:8126"

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

File (YAML)

tracing:
  datadog:
    localAgentHostPort: localhost:8126

File (TOML)

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

CLI

--tracing.datadog.localAgentHostPort=localhost:8126

localAgentSocket

Optional, Default=""

Local Agent Socket instructs the reporter to send spans to the Datadog Agent at this UNIX socket.

File (YAML)

tracing:
  datadog:
    localAgentSocket: /var/run/datadog/apm.socket

File (TOML)

[tracing]
  [tracing.datadog]
    localAgentSocket = "/var/run/datadog/apm.socket"

CLI

--tracing.datadog.localAgentSocket=/var/run/datadog/apm.socket

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"

CLI

--tracing.datadog.globalTag=sample

globalTags

Optional, Default=empty

File (YAML)

tracing:
  datadog:
    globalTags:
      tag1: foo
      tag2: bar

File (TOML)

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

CLI

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

prioritySampling

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.

File (YAML)

tracing:
  datadog:

File (TOML)

[tracing]
  [tracing.datadog]
    prioritySampling = true

CLI

--tracing.datadog.prioritySampling=true
