Introduction​

The process management component supports cross-process tracinging features, which are especially useful for some temporarily running processes. The overall tracinging of the framework adopts the OpenTelemetry specification.

Usage Example​

Main Process​

main.go

package main

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

func main() {
    ctx := gctx.GetInitCtx()
    g.Log().Debug(ctx, `this is main process`)
    if err := gproc.ShellRun(ctx, `go run sub.go`); err != nil {
        panic(err)
    }
}

Subprocess​

sub.go

package main

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

func main() {
    ctx := gctx.GetInitCtx()
    g.Log().Debug(ctx, `this is sub process`)
}

Execution Result​

After execution, the terminal outputs the following:

$ 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

As you can see, the trace information has been automatically passed to the subprocess.
