[gdebug] Maintained? Unable to get it working
Is this PoC tool for ChannelZ maintained? If not, is there an alternative client for ChannelZ?
I think I had used this tool previously and was able to get it to work. So, this is likely my error.
Trying again to use it today with a new solution, I'm unable to do so. I'm not seeing any servers, channels etc. logged to the UI:
There are no obvious errors logged (see end).
I'm uncertain how I may go about debugging the issue.
I have a working gRPC client and server (:50051).
The server includes:
service.RegisterChannelzServiceToServer(grpcServer)
go.mod includes:
google.golang.org/grpc v1.23.0
I munged around slightly with the docker-compose.yaml but think it remains correct. I exposed the Envoy admin port and it appears to be working correctly.
