Types

type CheckMetrics

type CheckMetrics struct {
	CheckError           Meter
	HandleError          Meter
	TriggersCheckTime    Timer
	TriggersToCheckCount Histogram
}

CheckMetrics is a collection of metrics for trigger checks

type CheckerMetrics

type CheckerMetrics struct {
	LocalMetrics           *CheckMetrics
	RemoteMetrics          *CheckMetrics
	MetricEventsChannelLen Histogram
	UnusedTriggersCount    Histogram
	MetricEventsHandleTime Timer
}

CheckerMetrics is a collection of metrics used in checker

func (*CheckerMetrics) GetCheckMetrics

func (metrics *CheckerMetrics) GetCheckMetrics(trigger *moira.Trigger) *CheckMetrics

GetCheckMetrics return check metrics dependent on given trigger type

type Config

type Config struct {
	Enabled      bool
	RuntimeStats bool
	URI          string
	Prefix       string
	Interval     time.Duration
}

Config for graphite connection settings

type Counter

type Counter interface {
	Clear()
	Count() int64
	Dec(int64)
	Inc(int64)
}

Counter hold an int64 value that can be incremented and decremented.

type FilterMetrics

type FilterMetrics struct {
	TotalMetricsReceived    Counter
	ValidMetricsReceived    Counter
	MatchingMetricsReceived Counter
	MatchingTimer           Timer
	SavingTimer             Timer
	BuildTreeTimer          Timer
	MetricChannelLen        Histogram
	LineChannelLen          Histogram
}

FilterMetrics is a collection of metrics used in filter

type Gauge

type Gauge interface {
	Update(int64)
	Value() int64
}

Gauge hold an int64 value that can be set arbitrarily.

type Histogram

type Histogram interface {
	Clear()
	Count() int64
	Max() int64
	Mean() float64
	Min() int64
	Percentile(float64) float64
	Percentiles([]float64) []float64
	StdDev() float64
	Sum() int64
	Update(int64)
	Variance() float64
}

Histogram calculate distribution statistics from a series of int64 values.

type IndexMetrics

type IndexMetrics struct {
	IndexedTriggersCount  Histogram
	IndexActualizationLag Timer
}

IndexMetrics is a collection of metrics used in full-text search index

type Meter

type Meter interface {
	Count() int64
	Mark(int64)
	Rate1() float64
	Rate5() float64
	Rate15() float64
	RateMean() float64
}

Meter count events to produce exponentially-weighted moving average rates at one-, five-, and fifteen-minutes and a mean rate.

type MetricsMap

type MetricsMap interface {
	AddMetric(name, path string)
	GetMetric(name string) (Meter, bool)
}

MetricsMap implements meter collection abstraction

type NotifierMetrics

type NotifierMetrics struct {
	SubsMalformed          Meter
	EventsReceived         Meter
	EventsMalformed        Meter
	EventsProcessingFailed Meter
	SendingFailed          Meter
	SendersOkMetrics       MetricsMap
	SendersFailedMetrics   MetricsMap
}

NotifierMetrics is a collection of metrics used in notifier

type Timer

type Timer interface {
	Count() int64
	Max() int64
	Mean() float64
	Min() int64
	Percentile(float64) float64
	Percentiles([]float64) []float64
	Rate1() float64
	Rate5() float64
	Rate15() float64
	RateMean() float64
	StdDev() float64
	Sum() int64
	Time(func())
	Update(time.Duration)
	UpdateSince(time.Time)
	Variance() float64
}

Timer capture the duration and rate of events.
