OTEL Agent How to disable logging

We are using OTEL Java agent as follow

java -javaagent:path/to/opentelemetry-javaagent.jar \
     -Dotel.resource.attributes=service.name=your-service-name \
     -Dotel.traces.exporter=jaeger\
     -Dotel.exporter.jaeger.endpoint=<IP>
     -jar myapp.jar

whenever Dotel.exporter.jaeger.endpoint is not reachable or for any other issues, it will print out the error messages

example:

otel.javaagent 2022-04-27 17:44:59:056 +0530] [OkHttp http://localhost:55680/...] ERROR io.opentelemetry.exporter.otlp.internal.grpc.OkHttpGrpcExporter - Failed to export spans. The request could not be executed.

Can we disable the logging for OTEL Java Agent or set log level for OTEL Java Agent?

You can define and env variable that will disable logs exporting with:

OTEL_LOGS_EXPORTER=none

You can set the system property - otel.javaagent.logging or environment variable - OTEL_JAVAAGENT_LOGGING to none.

You can simply switch off the logging completely for the OpenTelemetry Java Agent with this command line argument on starting the JVM:

-Dio.opentelemetry.javaagent.slf4j.simpleLogger.defaultLogLevel=off

This will suppress the otel.javaagent messages on missing exporter endpoint.

You can use a command line argument to change the log level but since this is an error it will still be written to the console.

I'm not sure why you would want to - but you could create a custom agent that does not log this issue, or logs it with a lower level.
