Feature Request

Outputting OTEL Self Diagnostics log to Console instead of file. Refer this GIT hub issue for more details - #2699 (comment)

Before opening a feature request against this repo, consider whether the feature
should/could be implemented in the other OpenTelemetry client
libraries. If so, please open an issue on
opentelemetry-specification
first.

Is your feature request related to a problem?
Yes. When GRPC calls are failing, we would like to have visibility in to how often it happens. Since we are using open shift containers, we would like to have OTEL Self Diagnostics log to Console so we can pull these in to Splunk.

If so, provide a concise description of the problem.

Describe the solution you'd like:
see above

What do you want to happen instead? What is the expected behavior?
see above

Describe alternatives you've considered.
We could write our own listener but this option should be provided by framework, so it can benefit all customers using the framework.

Which alternative solutions or features have you considered?
see above

I keep finding myself implementing this pattern. In Kubernetes it's not very convenient to output to a file - writing to stderr tends to be a much simpler solution to this.

A ConfigMap would still let us use the config file to switch this on and off during runtime, but perhaps we could add an "output" setting to switch between file output and stderr?

{
    "Output": "stderr"
    "LogLevel": "Warning"
}
