Debugging

Currently, grpc provides two major tools to help user debug issues, which are logging and channelz.

Logs

gRPC has put substantial logging instruments on critical paths of gRPC to help users debug issues. The Environment Variables doc describes the environment variables that control debug logging.

To enable full debug logging, run the code with the following environment variables: GRPC_TRACE=all GRPC_VERBOSITY=DEBUG.

Channelz

We also provide a runtime debugging tool, Channelz, to help users with live debugging.

See the channelz blog post here (link) for details about how to use channelz service to debug live program.

Try it

The example is able to showcase how logging and channelz can help with debugging. See the channelz blog post linked above for full explanation.
