This is theGoclient library forPrometheus. It has two separate parts, one for instrumenting application code, and one for creating clients that talk to the Prometheus HTTP API. Version Compatibility This library supports the three most recent major releases of Go. While it may function with olde...
简单使用 packagemainimport("context""github.com/prometheus/client_golang/api"v1"github.com/prometheus/client_golang/api/prometheus/v1""github.com/prometheus/common/model"log"github.com/sirupsen/logrus""time")funcmain(){// 创建一个 prom 客户端client,err:=api.NewClient(api.Config{Address:"http...
在等待时间结束后执行任务timer :=time.NewTimer(waitTime)//使用一个无限循环来控制协程的执行for{<-timer.C//等待定时器的触发事件//执行你的协程任务gofunc
我们可以借助Prometheus,这是一款开源的监控与报警系统,并且提供了多种语言的客户端库,其中就包括Go语言。Prometheus客户端库使用方式如下: package main import ( "net/http" "github.com/prometheus/client_golang/prometheus/promhttp" ) func main() { // 注册路由 http.Handle("/metrics", promhttp.Handler(...

一般Prometheus部署在监控云原生集群上,从Pod使用Kubernetes API官方客户端库(client-go)提供了更为简便的方法:rest.InClusterConfig()。API Server地址是从POD的环境变量KUBERNETES_SERVICE_HOST和KUBERNETES_SERVICE_PORT构建出来,token以及ca信息从POD固定的文件中获取,因此这种场景下kubernetes_sd_configs中api_server和ca...
2、go程序接入prometheus 参考:https://prometheus.io/docs/guides/go-application/ go默认基础指标 packagemainimport("net/http""github.com/prometheus/client_golang/prometheus/promhttp")funcmain(){ http.Handle("/metrics", promhttp.Handler())
通过阿里云Prometheus监控Go应用的操作流程如下图所示。 步骤一:为应用埋点 为应用埋点以暴露Go应用数据的操作步骤如下: 将监控包导入Go应用。 import ( "fmt" "github.com/prometheus/client_golang/prometheus/promhttp" "net/http" "strconv" ) 将监控接口绑定至promhttp.Handler()。 http.Handle(path, prom...
go get github.com/prometheus/client_golang/prometheus/promhttp 1. 2. 3. 4. 5. 6. 2.2 Go应用接入Prometheus 创建个Golang项目,项目结构如下: 2.3 运行时指标 1)准备一个 HTTP 服务,路径通常使用/metrics。可以直接使用prometheus/promhttp里提供的Handlerhttp://localhost:8080/metrics暴露 Golang 应用的一...
可以看到,上述代码中,我们仅仅启动了HTTP Server并将client_golang提供的一个默认的HTTP Handler注册到了路径/metrics上。我们可以试着运行该程序并对接口进行访问,结果如下: $ curl http://127.0.0.1:8080/metrics ...
