type Option 

type Option func(*Config)

func WithBackoffInterval 

func WithBackoffInterval(internal time.Duration) Option

WithBackoffInterval set wait interval between retries when data upload fail

func WithBlockProfile 

func WithBlockProfile(rate *int) Option

WithBlockProfile enables blockProfile with rate, rate's unit is nanoseconds, which means 1 blocking event per rate nanoseconds is reported. see runtime.SetBlockProfileRate BlockProfile is disabled by default. In most cases, BlockProfile has low CPU overhead. However, please be aware that BlockProfile can cause CPU overhead under certain circumstance. (Setting rate to 10,000ns may cause up to 4% CPU overhead in some scenario according to document https://github.com/DataDog/go-profiler-notes/blob/main/guide/README.md#block-profiler-limitations). For safety defaultBlockRate is set to 100,000,000ns(100ms), meaning block events with duration longer than 100ms will be recorded, while block events with duration of 1ms has a 1% chance to be recorded.

func WithHTTPEndPoint 

func WithHTTPEndPoint(schema, host string, timeout time.Duration) Option

WithHTTPEndPoint set http endpoint for both settings and profile data thus bypass server-agent, which is useful where server-agent is not installed

func WithLogger 

func WithLogger(l logger.Logger) Option

WithLogger set logger used in profiler

func WithMutexProfile 

func WithMutexProfile(fraction *int) Option

WithMutexProfile enables mutexProfile with fraction, which means on average 1/fraction events are reported. see runtime.SetMutexProfileFraction MutexProfile is disabled by default. When using modest fraction (e.g. 100) MutexProfile has little impact on performance.

func WithRetryCount 

func WithRetryCount(count int) Option

WithRetryCount set retry count when data upload fail

type ProfileCollector 

type ProfileCollector interface {
	Name() string
	FileName() string
	SupportDelta() bool //see go/src/net/http/pprof.go -> profileSupportsDelta
	GetPrevious() *profile.Profile
	SetPrevious(*profile.Profile)
	Collect(durationSeconds int64, isSnapshot, useCache bool, targetDeltaSampleTypes []common.SampleType) (*common.ProfileData, error)
}

func GetProfileCollector 

func GetProfileCollector(pt common.ProfileType) ProfileCollector

type Profiler 

type Profiler struct {
	// contains filtered or unexported fields
}

func NewProfiler 

func NewProfiler(serviceType, service string, opts ...Option) *Profiler

NewProfiler fetch profileTasks from remoteConfig then profile and send pprof data to backend

func (*Profiler) DebugTasks 

func (p *Profiler) DebugTasks(tasks []*common.Task)

DebugTasks create a debug task. DEBUG ONLY.

func (*Profiler) Start 

func (p *Profiler) Start()

func (*Profiler) Stop 

func (p *Profiler) Stop()
