The Gin Framework Metrics Middleware

Preface

Many small companies don’t have such a large architecture for micro-services when they do websites. A simple solution for viewing application traffic is very important. This repository is a middleware that integrates seamlessly with Gin.

How to use

• install the metrics lib

go get github.com/kylesliu/gin_exporter

• run the server

package main
import (
    "github.com/gin-gonic/gin"
    "github.com/kylesliu/gin_exporter"
)
func main() {
    app := gin.Default()
    gin.SetMode(gin.DebugMode)
    app.GET("demo1", func(c *gin.Context) {
        c.JSON(200, gin.H{
            "code": 200,
            "msg":  "demo1",
        })
    })
    gin_exporter.Default(app)
    if err := app.Run("127.0.0.1:9000"); err != nil {
        panic(err.Error())
    }
}
