OpenTelemetry support

[emanuelef]

Hi,
I just wanted to ask since which version OpenTelemetry is supported.

I set the following env vars on ditto things (v2.3.2) but I'm not seeing the traces.

OTEL_EXPORTER_OTLP_ENDPOINT: satellite.svc.cluster.local:8184
OTEL_EXPORTER_OTLP_TRACES_PROTOCOL: grpc
OTEL_EXPORTER_OTLP_TRACES_INSECURE: true
OTEL_METRICS_EXPORTER: none
DITTO_TRACING_ENABLED: true
DITTO_TRACING_SAMPLER: always

Do I also need to set service name with OTEL_SERVICE_NAME ?

Thanks

Should be available since 2.1.0.
I would however not recommend such an old version, version 3.x resolved a lot of stability and performance issues.

Everything required to configure should be documented at https://www.eclipse.org/ditto/installation-operating.html#tracing
