# 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](https://github.com/grpc/grpc-node/blob/master/doc/environment_variables.md) 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](https://grpc.io/blog/a-short-introduction-to-channelz/)) 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.
