What Operating System are you using (both controller, and any agents involved in the problem)?

Open telementry plugin do not close it's sockets or files.

Reproduction steps

1. Add this config:

openTelemetry:
    authentication:
      otlpHeaderAuthentication:
        headerName: "api-key"
        headerValueId: "<some-value>"
    configurationProperties: |-
      otel.logs.exporter=otlp
      otel.logs.mirror_to_disk=true
    disabledResourceProviders: "io.opentelemetry.instrumentation.resources.ProcessResourceProvider"
    endpoint: "https://otlp.nr-data.net:4317"
    exportOtelConfigurationAsEnvironmentVariables: false
    ignoredSteps: "dir,echo,isUnix,pwd,properties"
    serviceName: "some app endpoint"
    serviceNamespace: "some name"

2. Observe number of files used by jenkins

Expected Results

The number of opened descriptors should stay constant after some time.

Actual Results

After enabling:

  otel.logs.exporter=otlp
  otel.logs.mirror_to_disk=true

Number of opened files sky rocket

Anything else?

Yes i will try it out, in next week. Thanks for quick response :)

@cyrille-leclerc I tested this out on a smaller dev instance and I don't see this type of behavior anymore.

[DuMaM]

Ok, i confirming that it works.
