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

File (YAML)

  1. tracing:
  2.   datadog:

File (TOML)

  1. [tracing]
  2.   [tracing.datadog]
  3.     localAgentHostPort = "127.0.0.1:8126"

CLI

  1. --tracing.datadog.localAgentHostPort=127.0.0.1:8126

debug

Optional, Default=false

Enables Datadog debug.

File (YAML)

  1. tracing:
  2.   datadog:
  3.     debug: true

File (TOML)

  1. [tracing]
  2.   [tracing.datadog]
  3.     debug = true

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

  3.     prioritySampling: true

File (TOML)

  1. [tracing]
