Stream eventlog data to the OpenTelemetry Collector.

Version Deprecated package0.7.0.0

Changelog

0.7.0.0

  • Add support for OTLP over HTTP/Protobuf. To use HTTP/Protobuf, use:

    • --otlp-protocol=http/protobuf
    • --otlp-endpoint=http://my-http-endpoint:my-http-port

    See demo-http-protobuf for a demo that uses eventlog-live-otelcol to sends data directly to Prometheus over HTTP/Protobuf.

  • BREAKING: Rename --otelcol command-line options to --otlp, and change the separate host/port/ssl options to --otlp-endpoint, which accepts an URL similar to the OTLP environment variables.

    Moreover, the certificate-store and ssl-key-log/ssl-key-log-from-env options are now prefixed by --otlp-grpc-, e.g., --otlp-grpc-ssl-key-log.

  • BREAKING: Rename profiles processors to call_stack_profile and cost_centre_stack_profile. These processors now respect the name given in the configuration file, e.g., using the default configuration, these profiles will be available in Pyroscope as...

    • ghc_eventlog_CallStackProfile:cpu:samples
    • ghc_eventlog_CostCentreStackProfile:cpu:samples

  • BREAKING: Change default semantics of the configuration file.

    Starting from version 0.7.0.0, if the key for any specific processor is present in the file, even if it sets none of the properties, the processor is enabled, and any missing keys will default to the values in this file. Otherwise, the processor is disabled. For instance, the following configuration will run only the heap_prof_sample processor with the default configuration.

    processors:
  metrics:
    heap_prof_sample:

    Previously, if any key in the configuration file was commented out, it was given the value in the default configuration. Unfortunately, this was very unintuitive. Consider the following configuration...

    processors:
  metrics:
    heap_prof_sample:
      name: ghc_eventlog_HeapProfSample
      aggregate: 5s
      export: 5s

    Previously, this would activate heap_prof_sample with the given configuration and activate all other processors with their default configuration. Moreover, if the user edited the file and commented out the heap_prof_sample section...

    processors:
  metrics:
#     heap_prof_sample:
#       name: ghc_eventlog_HeapProfSample
#       aggregate: 5s
#       export: 5s

    ...this would not deactive the heap_prof_sample processor. Rather, it would keep the heap_prof_sample processor active with its default configuration.
