[![PkgGoDev](https://pkg.go.dev/badge/github.com/rakyll/autopprof)](https://pkg.go.dev/github.com/rakyll/autopprof)

Pprof made easy at development time.

## Guide

Add autopprof.Capture to your main function.

```go

import "github.com/rakyll/autopprof"

autopprof.Capture(autopprof.CPUProfile{

    Duration: 30 * time.Second,

})

```

Run your program and send SIGQUIT to the process

(or CTRL+\\ on Mac).

Profile capturing will start. Pprof UI will be started

once capture is completed.

See [godoc](https://godoc.org/github.com/rakyll/autopprof) for other profile types.

## Why autopprof?

autopprof is a easy-to-setup pprof profile data collection library

for development time.

It highly depends on the standard library packages such as

[runtime/pprof](https://golang.org/pkg/runtime/pprof/) and the existing

tools such as `go tool pprof`.

Collecting and visualizing profiling data from Go programs is a

multi-step process. First, you need to collect and write the collected

data to a file. Then you should use the `go tool pprof` tool to analyze

and visualize.

autopprof makes it easier to collect and start the pprof UI with a

one-line configuration. It collects profiles once the process is triggered

with a SIGQUIT and starts the pprof UI with the collected data. Since it

does signal handling and starting the browser, it is only recommended

at development-time.

For production cases, please see the

[runtime/pprof](https://golang.org/pkg/runtime/pprof/)

and [net/http/pprof](https://golang.org/pkg/net/http/pprof/) packages.
