Types

type Config

type Config struct {
	Dir         string        `json:"dir"`
	Enabled     bool          `json:"enabled"`
	Freq        time.Duration `json:"freq"`
	MaxNumFiles int           `json:"maxNumFiles"`
}

Config that is used to describe the options of the continuous profiler.

type ContinuousProfiler

type ContinuousProfiler interface {
	Dispatch() error
	Shutdown()
}

ContinuousProfiler periodically captures CPU, memory, and lock profiles

func NewContinuous

func NewContinuous(dir string, freq time.Duration, maxNumFiles int) ContinuousProfiler

type Profiler

type Profiler interface {
	// StartCPUProfiler starts measuring the cpu utilization of this process
	StartCPUProfiler() error

	// StopCPUProfiler stops measuring the cpu utilization of this process
	StopCPUProfiler() error

	// MemoryProfile dumps the current memory utilization of this process
	MemoryProfile() error

	// LockProfile dumps the current lock statistics of this process
	LockProfile() error
}

Profiler provides helper methods for measuring the current performance of this process

func New

func New(dir string) Profiler
