Traefik Datadog Tracing Documentation	Traefik Proxy supports Datadog for tracing. Read the technical documentation to enable Datadog for observability.

Datadog

To enable the Datadog tracer:

tracing:
  datadog: {}

[tracing]
  [tracing.datadog]

--tracing.datadog=true

localAgentHostPort

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

debug

Optional, Default=false

Enables Datadog debug.

tracing:
  datadog:
    debug: true

[tracing]
  [tracing.datadog]
    debug = true

--tracing.datadog.debug=true

globalTag

??? warning "Deprecated in favor of the globalTags option."

_Optional, Default=empty_

Applies a shared key:value tag on all spans.

```yaml tab="File (YAML)"
tracing:
  datadog:
    globalTag: sample
```

```toml tab="File (TOML)"
[tracing]
  [tracing.datadog]
    globalTag = "sample"
```

```bash tab="CLI"
--tracing.datadog.globalTag=sample
```

globalTags

Optional, Default=empty

Applies a list of shared key:value tags on all spans.

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

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

--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.

tracing:
  datadog:
    prioritySampling: true

[tracing]
  [tracing.datadog]
    prioritySampling = true

--tracing.datadog.prioritySampling=true
