Tracing

Visualize the Requests Flow {: .subtitle }

The tracing system allows developers to visualize call flows in their infrastructure.

Traefik uses OpenTelemetry, an open standard designed for distributed tracing.

Please check our dedicated OTel docs to learn more.

To enable the tracing:

tracing: {}

[tracing]

--tracing=true

Common Options

--tracing.serviceName=traefik

sampleRate

Optional, Default=1.0

The proportion of requests to trace, specified between 0.0 and 1.0.

tracing:

[tracing]
    sampleRate = 0.2

--tracing.sampleRate=0.2

headers

Optional, Default={}

Defines additional headers to be sent with the span's payload.

tracing:
  headers:
    foo: bar
    baz: buz

[tracing]
