## Installation

    $ npm install metrics-stripe-charges

## Quickstart

Here's a full example of a [Geckoboard](https://github.com/segmentio/geckoboard) dashboard showing Stripe charge metrics:

```js
var Metrics = require('metrics');
var charges = require('metrics-stripe-charges');
var geckoboard = require('geckoboard')('api-key');

new Metrics()
  .every('10m', charges('stripe-key'))
  .use(function (metrics) {
    metrics.on('stripe charged', function (metric) {
      geckoboard('widget-id').number(metric.latest());
    });
  });
```

#### Filter Customers

You can further `filter` customers using [stripe-charges](https://github.com/segmentio/stripe-chages) filters:

```js
new Metrics()
  .every('10m', charges('stripe-key', { filter: filter }));

function filter (charge) {
  return charge.customer !== 'cus_8239d2jd9j'; // filter enterprise customer X
}
```

## Metrics

The metrics exposed by this plugin are:

- `stripe charges` - the number of charges
- `stripe charged` - the dollar amount charged

and are calculated for the last 30 days, last 52 weeks, and last 10 years.
