profile

Simple profiling support package for Go

installation

go get github.com/davecheney/profile

usage

Enabling profiling in your application is as simple as one line at the top of your main function

import "github.com/davecheney/profile"

func main() {
     defer profile.Start(profile.CPUProfile).Stop()
     ...
}

options

What to profile is controlled by the *profile.Config value passed to profile.Start. A nil Config is the same as choosing all the defaults. By default no profiles are enabled.

import "github.com/davecheney/profile"

func main() {
     cfg := profile.Config {
          CPUProfile: true,
          MemProfile: true,
          NoShutdownHook: true, // do not hook SIGINT
     }
     // p.Stop() must be called before the program exits to  
     // ensure profiling information is written to disk.
     p := profile.Start(&cfg)
     ...
}

Several convenience package level values are provided for cpu, memory, and block (contention) profiling.

For more complex options, consult the documentation on the profile.Config type.
