# Max

This module finds the max value in the time-frame given.

## how to use

Use it in alarms like this:

```
 alarm: my_alarm
    on: my_chart
lookup: max -1m unaligned of my_dimension
  warn: $this > 1000
```

`max` does not change the units. For example, if the chart units is `requests/sec`, the result
will be again expressed in the same units. 

It can also be used in APIs and badges as `&group=max` in the URL.

## Examples

Examining last 1 minute `successful` web server responses:
