span_kind: SERVER

tracer_provider:
  sampler:
    parent_based:
      root:
        rule_based_routing:
          fallback_sampler:
            always_on:
          span_kind: SERVER
          rules:
            - action: DROP
              attribute: url.path
              pattern: /health.*
            - action: DROP
              attribute: url.path
              pattern: /actuator.*

I want to drop the redis heartbeat, I don't know if it's supported.

            - action: DROP
              attribute: db.statement
              pattern: ^PING$
            - action: DROP
              attribute: db.statement
              pattern: ^QUIT$

Describe the solution you'd like

I looked at https://github.com/open-telemetry/opentelemetry-java-contrib/tree/main/cel-sampler, is it necessary to add the CEL-Based sampler to the extension?

I think you could do something like:

tracer_provider:
  sampler:
    parent_based:
      root:
        rule_based_routing:
          fallback_sampler:
            rule_based_routing:
              fallback_sampler:
                always_on:
              span_kind: CLIENT
              rules:
                - action: DROP
                  attribute: db.statement
                  pattern: ^PING$
                - action: DROP
                  attribute: db.statement
                  pattern: ^QUIT$
          span_kind: SERVER
          rules:
            - action: DROP
              attribute: url.path
              pattern: /health.*
            - action: DROP
              attribute: url.path
              pattern: /actuator.*

I looked at https://github.com/open-telemetry/opentelemetry-java-contrib/tree/main/cel-sampler, is it necessary to add the CEL-Based sampler to the extension?

yes, though that module could be enhanced to publish a shaded jar that can be used directly as an extension similar to https://github.com/open-telemetry/opentelemetry-java-contrib/tree/main/gcp-auth-extension#with-opentelemetry-java-agent
