Go statsviz 支持浏览器实时可视化 Go 程序运行指标库

Go statsviz 是一个支持在浏览器中可视化 Go 程序运行时指标的实时图表，包括堆、对象、goroutines、GC 暂停、调度器等指标

使用

• 支持与 echo、fasthttp、fiber、gin 等集成，参考
  • Supported metrics
  • 支持的图表（不同 go 版本会有不同）：
    • Heap (global)
    • Heap (details)
    • Live Objects in Heap
    • Live Bytes in Heap
    • MSpan/MCache
    • Memory classes
    • Goroutines
    • Size Classes
    • GC Scan
    • GC Cycles
    • Stop-the-world Pause Latencies
    • CPU Classes (GC)
    • Time Goroutines Spend in ‘Runnable’ state
    • Time Goroutines Spend Blocked on Mutexes
    • Starting Size of Goroutines Stacks
    • Goroutine Scheduling Events
    • CGO Calls

package main

import (
	"fmt"
	"log"
	"net/http"

	"github.com/arl/statsviz"
	example "github.com/arl/statsviz/_example"
)

func main() {
	// Force the GC to work to make the plots "move".
	go example.Work()

	// Register a Statsviz server on the default mux.
	statsviz.Register(http.DefaultServeMux)

	fmt.Println("Point your browser to http://localhost:8080/debug/statsviz/")
	log.Fatal(http.ListenAndServe(":8080", nil))
}

• 启动，服务监听在 http://localhost:8080/debug/statsviz
