這是官方的prometheus golang-client示例：package mainimport ( "log" "net/http" "github.com/prometheus/client_golang/prometheus" "github.com/prometheus/client_golang/prometheus/promhttp")var cpuTemp = prometheus.NewGauge(prometheus.GaugeOpts{ Name: "cpu_temperature_celsius", Help: "Current temperature of the CPU.", })func init() { // Metrics have to be registered to be exposed: prometheus.MustRegister(cpuTemp)}func main() { cpuTemp.Set(65.3) // The Handler function provides a default handler to expose metrics // via an HTTP server. "/metrics" is the usual endpoint for that. http.Handle("/metrics", promhttp.Handler()) log.Fatal(http.ListenAndServe(":8080", nil))}在此代碼中，http 服務(wù)器使用該庫。promhttp使用框架時如何修改指標處理程序？我沒有在文檔中找到答案。gin

我們只是利用處理程序。promhttp
package main
import (
"github.com/gin-gonic/gin"
"github.com/prometheus/client_golang/prometheus"
"github.com/prometheus/client_golang/prometheus/promhttp"
)
var cpuTemp = prometheus.NewGauge(prometheus.GaugeOpts{
Name: "cpu_temperature_celsius",
Help: "Current temperature of the CPU.",
})
func init() {
prometheus.MustRegister(cpuTemp)
}
func prometheusHandler() gin.HandlerFunc {
h := promhttp.Handler()
return func(c *gin.Context) {
h.ServeHTTP(c.Writer, c.Request)
}
}
func main() {
cpuTemp.Set(65.3)
r := gin.New()
r.GET("/", func(c *gin.Context) {
c.JSON(200, "Hello world!")
})
r.GET("/metrics", prometheusHandler())
r.Run()
}
或者我們總是可以切換到普羅米修斯中間件 - https://github.com/zsais/go-gin-prometheus

我正在將普羅米修斯與其他庫 https://github.com/Depado/ginprom 一起使用：
package main
import (
"github.com/Depado/ginprom"
"github.com/gin-gonic/gin"
)
func main() {
r := gin.Default()
p := ginprom.New(
ginprom.Engine(r),
ginprom.Subsystem("gin"),
ginprom.Path("/metrics"),
)
r.Use(p.Instrument())
r.GET("/hello/:id", func(c *gin.Context) {})
r.GET("/world/:id", func(c *gin.Context) {})
r.Run("127.0.0.1:8080")
}
