Linux Ftrace for Go.

Simplify Linux ftrace processing with Go.

Usage

package main

import (
    "fmt"
    "github.com/kofemann/linux_ftrace"
    "os"
    "os/signal"
)

func main() {

    eventTrace := ftrace.NewEventTrace("sunrpc/xprt_transmit")
    eventTrace.Enable()

    c := eventTrace.EventSource()

    signalChan := make(chan os.Signal, 1)
    signal.Notify(signalChan, os.Interrupt)
loop:
    for {
        select {
        case l, ok := <-c:
            fmt.Println(l.String())
            if !ok {
                break loop
            }
        case <-signalChan:
            fmt.Println("\nInterrupted...")
            eventTrace.Disable()
        }

How to contribute

linux_ftrace uses the linux kernel model of using git not only a source repository, but also as a way to track contributions and copyrights.

Each submitted patch must have a "Signed-off-by" line. Patches without this line will not be accepted.

The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below:

        Developer's Certificate of Origin 1.1

        By making a contribution to this project, I certify that:

        (a) The contribution was created in whole or in part by me and I
            have the right to submit it under the open source license
            indicated in the file; or

        (b) The contribution is based upon previous work that, to the best
            of my knowledge, is covered under an appropriate open source
            license and I have the right under that license to submit that
            work with modifications, whether created in whole or in part
            by me, under the same open source license (unless I am
            permitted to submit under a different license), as indicated
            in the file; or

        (c) The contribution was provided directly to me by some other
            person who certified (a), (b) or (c) and I have not modified
            it.

	(d) I understand and agree that this project and the contribution
	    are public and that a record of the contribution (including all
	    personal information I submit with it, including my sign-off) is
	    maintained indefinitely and may be redistributed consistent with
	    this project or the open source license(s) involved.

then you just add a line saying ( git commit -s )

using your real name (sorry, no pseudonyms or anonymous contributions.)
