[TOC] ## 概述 dashboard 可視化hystrix的上報信息 ## 啟動 hystrix-dashboard:latest 使用 docker 安裝 ``` docker run -d -p 9002:9002 --name hystrix-dashboard \ mlabouardy/hystrix-dashboard:latest ``` ## code <details> <summary> main.go</summary> ``` package main import ( "github.com/afex/hystrix-go/hystrix" "net" "net/http" _ "net/http/pprof" ) func main() { hystrix.ConfigureCommand("my_command", hystrix.CommandConfig{ Timeout: 1000, MaxConcurrentRequests: 100, ErrorPercentThreshold: 25, }) hystrixStreamHandler := hystrix.NewStreamHandler() hystrixStreamHandler.Start() go func() { err := http.ListenAndServe(net.JoinHostPort("", "9096"), hystrixStreamHandler) if err != nil { panic(err) } }() http.HandleFunc("/test", func(resp http.ResponseWriter, req *http.Request) { output := make(chan bool, 1) errors := hystrix.Go("test", func() error { output <- true return nil }, nil) select { case <-output: resp.Write([]byte("success")) case err := <-errors: resp.Write([]byte(err.Error())) } }) err := http.ListenAndServe(":1234", nil) if err != nil { panic(err) } } ``` </details> <br /> ## 使用 瀏覽器訪問 ``` http://127.0.0.1:9002/hystrix ``` 在框中輸入 ``` http://192.168.31.20:9096/hystrix.stream ``` > 注意1: 輸入的 IP 必須為局域網ip,而非 127.0.0.1 > 注意2: 直接訪問 http://ip:9096/hystrix.stream 可能無法訪問,需要先觸發一次 http://ip:1234/test 的http 請求才行
