prometheus使用记录

exporter counter demo

// add promhttp
beego.Handler("/metrics", promhttp.Handler())

// 或者
handler := http.NewServeMux()
handler.Handle("/metrics", promhttp.Handler())

// 不带label的counter使用方式
// 声明metric
var (
 codeCounter = prometheus.NewCounter(
 prometheus.CounterOpts{
 Name: "http_request_total_code",
 Help: "total request code controller",
 },
 )
)

// 注册metrics
func init() {
 prometheus.MustRegister(codeCounter)
}

// 在需要的地方进行调用
codeCounter.Inc()


// 带label的counter的使用方式
// 声明metric
var (
 openfalconAlarmCounterVec = prometheus.NewCounterVec(
 prometheus.CounterOpts{
 Name: "openfalcon_alarm_total",
 Help: "Total number of openfalcon alarms",
 },
 []string{"level"},
 )
)

// 注册metrics
func init() {
 prometheus.MustRegister(openfalconAlarmCounterVec)
}

// 在需要的地方进行调用
openfalconAlarmCounterVec.WithLabelValues("0").Inc()
