Is it possible to use processors from opentelemetry-collector-contrib?

[niklasteichmann]

Hi everyone,
I want to use a processor that is not part of opentelemetry-collector-core in Jaeger, specifically the redaction processor.

Is there any way to get this to work?

Sorry if this question was answered before, I searched for "contrib" and "processor" but couldn't find anything.

Hey @niklasteichmann, I'm here to help you with any bugs, questions, or contributions you have. Let's dive in and figure this out together!

Yes, it is possible to use processors from the opentelemetry-collector-contrib repository in Jaeger. Jaeger is built on top of the OpenTelemetry Collector framework, which allows you to configure it to include processors from opentelemetry-collector-contrib. You can specify these processors in your configuration file, similar to how you would configure an OpenTelemetry Collector.

For example, to include a processor like the Tail Sampling Processor, you would add it to your configuration like this:

processors:
  tailsampling:
    decision_wait: 5s
    num_traces: 10000
    expected_new_traces_per_sec: 100
    policies:
      - name: test-policy
        type: always_sample

This setup can be adapted for other processors, such as the redaction processor, by following the specific configuration requirements for that processor ^[1][2].

It is only possible to use the components that are directly included in the Jaeger binary, which are enumerated in the docs https://www.jaegertracing.io/docs/2.2/architecture/#opentelemetry-components

If you want to use any other contrib (or otherwise) components you should run an OTEL Collector in front of Jaeger, as OTEL Collector allows more flexibility in how to include plugins.
