Introduction
The GoFrame command management component also supports cross-process tracing features, which are particularly useful for processes that run temporarily.
The overall tracing of the framework adopts the OpenTelemetry specification.
Usage Example
Main Process
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())
}
Sub Process
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())
}
Execution Result
After execution, the terminal output is as follows:
$ 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
You can see that the link information has been automatically passed to the sub-process.
