基本介绍

GoFrame 命令管理组件也支持跨进程的链路跟踪特性,特别是对于一些临时运行的进程特别有用。

框架整体的链路跟踪都是采用的 OpenTelemetry 规范。

使用示例

主进程

main.go

package main

import (
"context"

"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/os/gcmd"
"github.com/gogf/gf/v2/os/gctx"
"github.com/gogf/gf/v2/os/gproc"
)

var (
Main = &gcmd.Command{
Name: "main",
Brief: "main process",
Func: func(ctx context.Context, parser *gcmd.Parser) (err error) {
g.Log().Debug(ctx, `this is main process`)
return gproc.ShellRun(ctx, `go run sub.go`)
},
}
)

func main() {
Main.Run(gctx.GetInitCtx())
}

子进程

sub.go

package main

import (
"context"

"github.com/gogf/gf/v2/frame/g"
"github.com/gogf/gf/v2/os/gcmd"
"github.com/gogf/gf/v2/os/gctx"
)

var (
Sub = &gcmd.Command{
Name: "sub",
Brief: "sub process",
Func: func(ctx context.Context, parser *gcmd.Parser) (err error) {
g.Log().Debug(ctx, `this is sub process`)
return nil
},
}
)

func main() {
Sub.Run(gctx.GetInitCtx())
}

执行结果

执行后,终端输出如下:

$ go run main.go
2022-06-21 20:35:06.196 [DEBU] {00698a61e2a2fa1661da5d7993d72e8c} this is main process
2022-06-21 20:35:07.482 [DEBU] {00698a61e2a2fa1661da5d7993d72e8c} this is sub process

可以看到,链路信息已经自动传递给了子进程。
