func (h *HealthPing) PutResult(tag string, rtt time.Duration)

PutResult put a ping rtt to results

func (*HealthPing) StartScheduler

func (h *HealthPing) StartScheduler(selector func() ([]string, error))

StartScheduler implements the HealthChecker

func (*HealthPing) StopScheduler

func (h *HealthPing) StopScheduler()

StopScheduler implements the HealthChecker

type HealthPingConfig

type HealthPingConfig struct {

	// destination url, need 204 for success return
	// default https://connectivitycheck.gstatic.com/generate_204
	Destination string `protobuf:"bytes,1,opt,name=destination,proto3" json:"destination,omitempty"`

type HealthPingRTTS

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

HealthPingRTTS holds ping rtts for health Checker

func NewHealthPingResult

func NewHealthPingResult(cap int, validity time.Duration) *HealthPingRTTS

NewHealthPingResult returns a *HealthPingResult with specified capacity

func (*HealthPingRTTS) Get

func (h *HealthPingRTTS) Get() *HealthPingStats

Get gets statistics of the HealthPingRTTS

func (*HealthPingRTTS) GetWithCache

func (h *HealthPingRTTS) GetWithCache() *HealthPingStats

GetWithCache get statistics and write cache for next call Make sure use Mutex.Lock() before calling it, RWMutex.RLock() is not an option since it writes cache

func (*HealthPingRTTS) Put

func (h *HealthPingRTTS) Put(d time.Duration)

Put puts a new rtt to the HealthPingResult

type HealthPingSettings

type HealthPingSettings struct {
	Destination   string        `json:"destination"`
	Connectivity  string        `json:"connectivity"`
	Interval      time.Duration `json:"interval"`
