prometheus与grafana的安装

grom接入Prometheus,grafana-CSDN博客

Prometheus 动态加载

我们想给Prometheus新增监听任务新增ginapp项目只需要在原来的配置文件下面新增ginapp相关metric

在docker compose文件下面新增

执行

docker-compose up -d

curl -X POST http://localhost:9090/-/reload

granfa配置新的job

配置golang dashboard模版

配置之后我们看以在dashboard看到

Gin框架中间件配置

package initialization

import (
	"awesomeProject3/middware"
	"awesomeProject3/router"
	"github.com/Depado/ginprom"
	"github.com/gin-gonic/gin"
	_ "net/http/pprof"
)

func Routers() *gin.Engine {
	r := gin.New()
	r.Use(middware.GinRecovery(true), middware.GinZapLogger())
	r.Use(middware.Cors())
	router.InitOrderRouter(r)
	p := ginprom.New(
		ginprom.Engine(r),
		ginprom.Subsystem("gin"),
	)

	r.Use(p.Instrument())
	return r
}

pprof配置

package router

import (
	"awesomeProject3/api"
	"github.com/gin-gonic/gin"
	"net/http"
	"net/http/pprof"
)

func InitOrderRouter(Router *gin.Engine) {
	Router.GET("/health", func(c *gin.Context) {
		c.JSON(http.StatusOK, gin.H{
			"code":    http.StatusOK,
			"success": true,
		})
	})
	// 定义一个简单的GET路由
	Router.GET("/v1/ping", func(c *gin.Context) {

		c.JSON(http.StatusOK, gin.H{
			"message": "pong",
		})
	})

	Router.GET("/test", api.TestHandler) //

	pprofGroup := Router.Group("/debug/pprof")
	{
		pprofGroup.GET("/", gin.WrapF(pprof.Index))
		pprofGroup.GET("/cmdline", gin.WrapF(pprof.Cmdline))
		pprofGroup.GET("/profile", gin.WrapF(pprof.Profile))
		pprofGroup.GET("/symbol", gin.WrapF(pprof.Symbol))
		pprofGroup.GET("/trace", gin.WrapF(pprof.Trace))
		pprofGroup.GET("/allocs", gin.WrapH(pprof.Handler("allocs")))
		pprofGroup.GET("/block", gin.WrapH(pprof.Handler("block")))
		pprofGroup.GET("/goroutine", gin.WrapH(pprof.Handler("goroutine")))
		pprofGroup.GET("/heap", gin.WrapH(pprof.Handler("heap")))
		pprofGroup.GET("/mutex", gin.WrapH(pprof.Handler("mutex")))
		pprofGroup.GET("/threadcreate", gin.WrapH(pprof.Handler("threadcreate")))
	}
}
