Eru-Metric

A library for watching container metrics and send to remote.

This repo implement open-falcon methods you can write your methods by your self.

How

• write a func to implement Send method if you want send metircs to other place.

func Send(data map[string]float64, endpoint, tag string, timestamp, step int64) error

• set metric global setting

SetGlobalSetting(client Remote, timeout, forceTimeout time.Duration, vlanPrefix, defaultVlan string)

• create a backend object which implemented Send interface.

• create a metric for each container.

CreateMetric(step time.Duration, client Remote, tag, endpoint string)

• init metric object

InitMetric(cid string, pid int)

• update, calcuate, save and send

UpdateStats(cid string)
CalcRate(info map[string]uint64, now time.Time)
SaveLast(info map[string]uint64)
Send(rate map[string]float64)

• exit metirc

Exit()

Example
