inneek@gmail.com has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/1250643?usp=email ) Change subject: grpc: Add NfsMetricsService and local credentials support Add a gRPC NfsMetricsService (CollectMetrics RPC) that collects in-memory Prometheus metrics (counters, gauges, and histograms) from libntirpc's registry and exports them as structured protobuf messages. This allows local monitoring agents to scrape Ganesha metrics directly over gRPC without an HTTP scraping endpoint. Also update the gRPC server initialization and configuration: - Add a Credentials_Type config option (LOCAL vs SSL, defaulting to LOCAL) so local metrics/admin clients on the same host can connect via LocalServerCredentials without requiring mTLS certificate files. - Rename Ganesha's grpc_shutdown() wrapper to grpc__shutdown() (matching grpc__init()) to avoid a symbol collision with libgrpc's built-in grpc_shutdown() function. ...................................................................... grpc: Add NfsMetricsService and local credentials support Add a gRPC NfsMetricsService (CollectMetrics RPC) that collects in-memory Prometheus metrics (counters, gauges, and histograms) from libntirpc's registry and exports them as structured protobuf messages.
