Monitoring / Tracing

Tracing

The relay proxy is able to trace the requests it is handling. This is done by using OpenTelemetry.

Configuration

To configure the tracing, you need to set in the configuration the endpoint to your OTLP collector.

# ...
openTelemetryOtlpEndpoint: http://localhost:4318
# ...

All your requests will be traced and sent to the collector with the service name go-feature-flag.

note

If you want to try the OpenTelemetry integration locally, follow this README to setup Jaeger and see your traces.

Monitoring

The relay proxy offers some endpoints for you to be able to see how it behaves.

/health

Making a GET request to the URL path /health will tell you if the relay proxy is ready to serve traffic.

This is useful especially for loadbalancer to know that they can send traffic to the service.

/info

Making a GET request to the URL path /info will give you information about the actual state of the relay proxy.

/metrics

This endpoint is providing metrics about the relay proxy in the prometheus format.
