> Get the netstat activity on a given port.
```
$ npm install --save netstats
```
```js
const netstats = require('netstats');
netstats(8017).then(results => {
console.log(results);
});
```
On a mac or linux, the output is the same output you would get from running `lsof -i :<port>`
```
[
'COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME',
'nc 20661 michael 3u IPv4 0x3b190d9d07c2c3db 0t0 TCP *:8017 (LISTEN)',
'nc 21145 michael 3u IPv4 0x3b190d9d054773db 0t0 TCP *:8017 (LISTEN)',
'Python 21221 michael 3u IPv4 0x3b190d9ceb8dfd7b 0t0 UDP localhost:8017'
];
```
On windows, the output is the same as running `netstat.exe -a -n -o | findstr :<port>`
```
