grpc_server_msg_received_total: Total number of RPC stream messages received on the server. Only observes +1 on non-stream server input, +N, where N>=0 on streaming server input.
Labels: grpc_type, grpc_service, grpc_method
grpc_server_msg_sent_total: Total number of gRPC stream messages sent by the server. Only observes +1 on non-stream server output, +N, where N>=0 on streaming server output.
Labels: grpc_type, grpc_service, grpc_method
grpc_server_handling_seconds: Histogram of response latency (seconds) of gRPC that had been application-level handled by the server.
