By default, the OpenTelemetry trace exporter will sample 100% of traces.
|
||||
See [OpenTelemetry's SDK configuration](https://opentelemetry.io/docs/reference/specification/sdk-environment-variables/#general-sdk-configuration) to customize the sampling strategy.

!!! info "Propagation"
|
||||
|
||||
Traefik supports the `OTEL_PROPAGATORS` env variable to set up the propragators. The supported propagators are:
|
||||
|
||||
- tracecontext (default)
|
||||
- baggage (default)
|
||||
- b3
|
||||
- b3multi
|
||||
- jaeger
|
||||
- xray
|
||||
- ottrace
|
||||
|
||||
Example of configuration:
|
||||
|
||||
OTEL_PROPAGATORS=b3,jaeger
