k8s中如何實現(xiàn)SchedulingLatency 指標查看，很多新手對此不是很清楚，為了幫助大家解決這個難題，下面小編將為大家詳細講解，有這方面需求的人可以來學習下，希望你能有所收獲。

讓客戶滿意是我們工作的目標，不斷超越客戶的期望值來自于我們對這個行業(yè)的熱愛。我們立志把好的技術(shù)通過有效、簡單的方式提供給客戶，將通過不懈努力成為客戶在信息化領(lǐng)域值得信任、有價值的長期合作伙伴，公司提供的服務(wù)項目有：域名注冊、網(wǎng)絡(luò)空間、營銷軟件、網(wǎng)站建設(shè)、石龍網(wǎng)站維護、網(wǎng)站推廣。1.1.metrics.go指標定義

pkg/scheduler/metrics/metrics.go

SchedulingLatency = prometheus.NewSummaryVec(
prometheus.SummaryOpts{
Subsystem: SchedulerSubsystem,
Name: SchedulingLatencyName,
Help: "Scheduling latency in seconds split by sub-parts of the scheduling operation",
// Make the sliding window of 5h.
// TODO: The value for this should be based on some SLI definition (long term).
MaxAge: 5 * time.Hour,
},
[]string{OperationLabel},

)

第64行：Scheduling latency in seconds split by sub-parts of the scheduling operation

一次調(diào)度被分割為子組件的操作時間的和

1.1.scheduler.go調(diào)度入口1.1.1.pkg/scheduler/scheduler.go

// Run begins watching and scheduling. It waits for cache to be synced, then starts a goroutine and returns immediately.
func (sched *Scheduler) Run() {
if !sched.config.WaitForCacheSync() {
return
}

go wait.Until(sched.scheduleOne, 0, sched.config.StopEverything)
}

1.1.1.核心調(diào)度邏輯順序

1.sched.schedule

2.sched.assumeVolumes

3.sched.assume

4.sched.bindVolumes

5.sched.Cache

6.sched.bind

1.1.generic_scheduler.go調(diào)度算法實現(xiàn)1.1.1.pkg/scheduler/core/generic_scheduler.go
