Tracing

Visualize the Requests Flow

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

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

Traefik supports six tracing backends:

• Jaeger
• Zipkin
• Datadog
• Instana
• Haystack
• Elastic

Configuration

By default, Traefik uses Jaeger as tracing backend.

To enable the tracing:

File (YAML)

tracing: {}

File (TOML)

[tracing]

CLI

--tracing=true

Common Options

serviceName

Required, Default=”traefik”

Service name used in selected backend.

File (YAML)

tracing:
  serviceName: traefik

File (TOML)

[tracing]
  serviceName = "traefik"

CLI

--tracing.serviceName=traefik

spanNameLimit

Required, Default=0

Span name limit allows for name truncation in case of very long names. This can prevent certain tracing providers to drop traces that exceed their length limits.

0 means no truncation will occur.

File (YAML)

tracing:
  spanNameLimit: 150

File (TOML)

[tracing]
  spanNameLimit = 150

CLI

--tracing.spanNameLimit=150
