Overview

Package service defines methods to register a gRPC client/service for a profiling service that is exposed in the same server. This service can be queried by a client to remotely manage the gRPC profiling behaviour of an application.

This package and all its methods are EXPERIMENTAL.

Functions

func Init

func Init(pc *ProfilingConfig) error

Init takes a *ProfilingConfig to initialize profiling (turned on/off depending on the value set in pc.Enabled) and register the profiling service in the server provided in pc.Server.

Types

type ProfilingConfig

type ProfilingConfig struct {
	// Setting this to true will enable profiling.
	Enabled bool

	// Profiling uses a circular buffer (ring buffer) to store statistics for
	// only the last few RPCs so that profiling stats do not grow unbounded. This
	// parameter defines the upper limit on the number of RPCs for which
	// statistics should be stored at any given time. An average RPC requires
	// approximately 2-3 KiB of memory for profiling-related statistics, so
	// choose an appropriate number based on the amount of memory you can afford.
	StreamStatsSize uint32

	// To expose the profiling service and its methods, a *grpc.Server must be
	// provided.
	Server *grpc.Server
}

ProfilingConfig defines configuration options for the Init method.
