nice-grpc-prometheus

Prometheus monitoring middleware for nice-grpc (version 0.2.11). Provides client and server interceptors to collect gRPC metrics (latency, request/response counts, active streams) using Prometheus default metrics. Integrates seamlessly with nice-grpc's interceptor pattern. No external dependencies beyond peer grpc-js and nice-grpc. Limited release cadence; last update in 2022. Differentiator: zero-config, opinionated Prometheus metrics for gRPC with nice-grpc.
