The helm chart for open-telemetry/opentelemetry-collector is complex, not easy to use or debug.
Do note you need at a mininum a service with:
- A receiver
- A processor
- An exporter
Or it just won’t work.
service: pipelines: traces: receivers: [otlp] processors: [batch] exporters: [otlp]
The listener is typically GRPC on port 4317.
