memwatch-sigusr2

================

Do a heap diff on SIGUSR2 in node.

Wraps completely [memwatch-next](http://npm.im/memwatch-next) and offers the same

API.

Install

-------

```sh

npm install memwatch-sigusr2 --save

```

Usage

-----

In your leaking app:

```js

var memwatch = require('memwatch-sigusr2')

memwatch.setup()

// to get the process PID, omit in production and use ps aux | grep node

console.log(process.pid)

```

Then to start calculating the diff, run:

```sh

kill -sigusr2 

```

To stop calculating the diff, run:

```sh

kill -sigusr2 

```

Then, you can read your diff with:

```sh

jsonlint /tmp/heap-diff-.json

```

Check [jsonlint](http://npm.im/jsonlint) for installation and usage

instructions.
