gotracers

gotracer provides emitters for Sysdig tracers.

Usage

Auto-generated span identifiers:

func myFunc() {
    spanID, err := tracers.Start("mytag")
    handleErr(err)
    defer tracers.End("mytag", spanID)
    ...
}

Custom span identifiers:

func myFunc(uniqueId uint64) {
    err := tracers.StartInt("mytag", uniqueId)
    handleErr(err)
    defer tracers.End("mytag", uniqueId)
    ...
}

func myFunc(uniqueId string) {
    spanID, err := tracers.StartStr("mytag", uniqueId)
    handleErr(err)
    defer tracers.End("mytag", spanID)
    ...
}
