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 initializationimport ("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 routerimport ("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")))}
}
