go-grpc-channelz is an open source project in Go providing observability into gRPC’s current state of connections (channels).
gRPC is a robust and highly scalable RPC system. It abstracts actual socket connections through the channel abstraction. Channels represent load-balanced, possibly auto-discovered remote servers. Gaining visibility into the current state of gRPC channels is priceless. Think netstat for your gRPC server/clien. Channelz is a gRPC spec exposing the inner state of gRPC channels. go-grpc-channelz, written in go, is a pluggable UI which uses the channelz gRPC API to query and display the current state of gRPC connections.
