Start the Collector locally to see data being exported. Write the following file:
# otel-collector-config.yaml
receivers:
otlp:
protocols:
grpc:
endpoint: 0.0.0.0:4317
exporters:
debug:
processors:
batch:
service:
pipelines:
metrics:
receivers: [otlp]
exporters: [debug]Then start the Docker container:
docker run \
-p 4317:4317 \
-v $(pwd)/otel-collector-config.yaml:/etc/otel/config.yaml \
otel/opentelemetry-collector-contrib:latest$ python example.pyThe resulting metrics will appear in the output from the collector and look similar to this:
