Metric Collector for Go-Chassis

This a metric collector for Go-Chassis which collects metrics of the microservices. It can collect metrics for each api's exposed by the micro-services. The same data can be exposed to Huawei CSE Governance Dashboard.

How to use

in main.go

import _ "github.com/huaweicse/cse-collector"

Introdction

The metrics collected 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

You need to configure your microservice to send the data at regular interval to Huawei CSE Dashboard.

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

If perticular micro service has more than one instance and if request has been sent to perticular instance then only for that instance all the value should change.
