            //httpRequestCounter.WithLabelValues("user", "/get").Inc()
         } else {

            httpRequestCounter.With(m).Add(float64(random))
         }
         i++
         time.Sleep(time.Second)
      }

   }()

   prometheus.MustRegister(httpRequestCounter)
   http.Handle("/metrics", promhttp.Handler())
   fmt.Println("====================== start metrics =================")
   http.ListenAndServe(":2112", nil)
}

已监测到数据

prometheus.yml 增加配置

  - job_name: 'test_count'
    metrics_path: /metrics
    static_configs:
      - targets: ['localhost:2112']

搜索service_http_request_total，面板查看到数据
