I expected the configuration validator to find pipeline issues related to invalid usage of connector components, however the collector fails to start due to invalid usage and exits.
Here is an example that defines a count connector and uses it as a receiver in a metrics pipeline:
---
receivers:
otlp:
protocols:
grpc:
http:
exporters:
logging:
connectors:
count:
service:
pipelines:
traces/in:
receivers: [otlp]
exporters: [logging]
metrics/out:
receivers: [count]
exporters: [logging]The config.yaml passes validation:
otel-validations(:|✔) %
🤘 docker run -v $(pwd)/config.yaml:/etc/otelcol-contrib/config.yaml ghcr.io/open-telemetry/opentelemetry-collector-releases/opentelemetry-collector-contrib:0.87.0 validate --config=/etc/otelcol-contrib/config.yaml
otel-validations(:|✔) %
🤘 echo $?
0However upon using this configuration, the collector reports an error and exits:
otel-validations(:|✔) %
🤘 docker run -v $(pwd)/config.yaml:/etc/otelcol-contrib/config.yaml ghcr.io/open-telemetry/opentelemetry-collector-releases/opentelemetry-collector-contrib:0.87.0
