How to Transform OpenTelemetry Collector Logs into JSON Format?

[nikhil-ht]

i'm currently working with the OpenTelemetry Collector and would like to format its logs in JSON. I've been using a YAML configuration file for the collector, but I'm unsure how to specify that the logs should be outputted in JSON format.

Here's a simplified version of my current configuration:

receivers:
  otlp:
    protocols:
      http:
        endpoint: 0.0.0.0:6666

exporters:
  logging:
    loglevel: warn
  otlphttp:
    endpoint: ${OTEL_EXPORTER_OTLP_ENDPOINT}
    auth:
      authenticator: basicauth/client

extensions:
  basicauth/client:
    client_auth: 
      username: ${USERNAME}
      password: ${PASSWORD}

service:
  extensions: [basicauth/client]
  pipelines:
    metrics:
      receivers: [otlp]
      exporters: [otlphttp]
    traces:
      receivers: [otlp]
      exporters: [otlphttp]
