golang實現向pushgateway推送數據

package commands

func main() {
    ExamplePusher_Push()

    completionTime := prometheus.NewGauge(prometheus.GaugeOpts{
        Name: "db_backup_last_completion_timestamp_seconds",
        Help: "The timestamp of the last successful completion of a DB backup.",
    })
    completionTime.SetToCurrentTime()

      // completionTime.Set(200)  // set可以設置任意值（float64）

if err := push.New("http://127.0.0.1:9091", "db_backup").   // push.New("pushgateway地址", "job名稱")
        Collector(completionTime).  // Collector(completionTime) 給指標賦值
        Grouping("db", "customers").Grouping("instance", "1.1.1.1").  // 給指標添加標簽，可以添加多個
        Push(); err != nil {
        fmt.Println("Could not push completion time to Pushgateway:", err)
    }
