=============
Get network traffic statistics from [vnStat](https://github.com/vergoh/vnstat).
[](https://github.com/fvdm/nodejs-vnstat-dumpdb/blob/master/CHANGELOG.md)

Example
-------
```js
var vnstat = require ('vnstat-dumpdb') ();
// Get traffic per day
vnstat.getStats ('eth0', function (err, data) {
if (err) {
console.log (err);
return;
}
console.log (data.traffic.days);
});
// Read config setting
vnstat.getConfig (function (err, config) {
if (err) {
console.log (err);
return;
}
console.log ('Interfaces updating every ' + config.UpdateInterval + ' minutes');
});
```
Installation
------------
Make sure you have **vnStat v1.13** or later.
`npm install vnstat-dumpdb`
Configuration
-------------
The module loads as a function to override the defaults:
setting | type | required | default | description
--------|--------|----------|---------|----------------------
bin | string | no | vnstat | Path to vnstat binary
iface | string | no | | i.e. `eth0` or `false` to list all
Callback & errors
-----------------
Each method below takes a callback _function_ which gets two arguments:
* `err` - Instance of `Error` or `null`
* `data` - Result `object` or not set when error
```js
function myCallback (err, data) {
if (err) {
console.log (err);
console.log (err.stack);
return;
}
console.log (data);
}
```
#### Errors
message | description | additional
------------------|-----------------------------------|---------------------------
no config | Can't load config for `getConfig` | `err.details`, `err.error`
invalid data | Can't read stats for `getStats` | `err.details`
invalid interface | `iface` is invalid or not set up |
getStats ( [iface], callback )
--------
Get statistics for one, multiple or all interfaces.
* One: `vnstat.getStats ('eth0', callback)`
* All: `vnstat.getStats (false, callback)`
```js
// Get traffic for interface en1
vnstat.getStats ('en1', console.log);
// Output
