Hi Lidi
how do i get debug logs? what location they are saved at?
I have done following and i dont see any extra information on stdout
#server side terminal

GRPC_TRACE=api,channel,call_error,connectivity_state,http,server_channel
root@fmx216:~/gRPC/grpc/examples/python/helloworld# python greeter_server.py
#client side terminal
