Simple profiling support package for Go
[![Build Status](https://travis-ci.org/pkg/profile.svg?branch=master)](https://travis-ci.org/pkg/profile) [![GoDoc](http://godoc.org/github.com/pkg/profile?status.svg)](http://godoc.org/github.com/pkg/profile)
installation
------------
go get github.com/pkg/profile
usage
-----
Enabling profiling in your application is as simple as one line at the top of your main function
```go
import "github.com/pkg/profile"
func main() {
defer profile.Start().Stop()
...
}
```
options
-------
What to profile is controlled by config value passed to profile.Start.
By default CPU profiling is enabled.
```go
import "github.com/pkg/profile"
func main() {
// p.Stop() must be called before the program exits to
// ensure profiling information is written to disk.
p := profile.Start(profile.MemProfile, profile.ProfilePath("."), profile.NoShutdownHook)
...
}
```
Several convenience package level values are provided for cpu, memory, and block (contention) profiling.
For more complex options, consult the [documentation](http://godoc.org/github.com/pkg/profile).
