Metric Collector for Go-Chassis
This is a reporter plugin for go-chassis
which report circuit breaker metrics to Huaweicloud.
How to use
in main.go
import _ "github.com/huaweicse/cse-collector"
Introdction
The metrics reported by this collector is listed below:
attempts
errors
successes
failures
rejects
shortCircuits
timeouts
fallbackSuccesses
fallbackFailures
totalDuration
runDuration
It also collects data for each api's:
Name string `json:"name"`
Desc string `json:"desc"`
Qps float64 `json:"qps"`
Latency int `json:"latency"`
L995 int `json:"l995"`
L99 int `json:"l99"`
L90 int `json:"l90"`
L75 int `json:"l75"`
L50 int `json:"l50"`
L25 int `json:"l25"`
L5 int `json:"l5"`
Rate float64 `json:"rate"`
Total int64 `json:"total"`
Failure int64 `json:"failure"`
ShortCircuited int64 `json:"shortCircuited"`
IsCircuitBreakerOpen bool `json:"isCircuitBreakerOpen"`
SemaphoreRejected int64 `json:"semaphoreRejected"`
ThreadPoolRejected int64 `json:"threadPoolRejected"`
CountTimeout int64 `json:"countTimeout"`
Configurations
in chassis.yaml file. You need to configure your micro service to send the data to Huaweicloud ServiceStage.
cse:
monitor:
client:
serverUri: https://cse.cn-north-1.myhwclouds.com:443
enable: true
Data Post
Every 2 sec data will be posted to monitoring server if serverUri is correct and enable is true
The data formate after post
