Is there a way to disable the tracingEnabled option used in ManagedChannelImplBuilder?

[zerocooldog]

I 'm only using the gRPC client, so I added three basic libraries as dependencies.

After that, I customized the package using shadowJar.

However, after implementing the client and communicating with the server, I encountered the following error. (Even though the error message appears, it seems that communication is working well.)

I found and analyzed the source of ManagedChannelImplBuilder, and I see that the tracingEnabled value is processed when it is set to true.

However, I don't know how to disable this option.

Is there a way to do it?

ps. The same error message is displayed even without using shadowJar.

That says "DEBUG." That's not an error. This is regular and expected behavior.

[zerocooldog]

I'm aware that it's related to debugging. I asked because I don't want to see the stack trace. I was wondering if it was possible to disable the output in debug using the tracingEnabled option.

Is there no way to handle this other than changing the log level for that specific package?

Correct. There is a way to configure it and it's to turn off debug logs. That's 100% typical for debug logs.

[hemanthtikyani]

@ejona86 Thank you for the details. It seems a bit weird having to turn-off debug logging to disable tracing. Can we add a way to disable tracing explicitly? It can be enabled by default.

[ejona86]

Debug logs have nothing to do with enabling tracing. Tracing with Census is implicitly enabled when the dependencies are available, and the error you see is it not being enabled because the dependencies aren't available. It has the same behavior independent of the debug logs, it's just that only the debug logs showed you what was going on.
