-# Sum
-
-This module sums all the values in the time-frame requested.
-
-You can use `sum` to find the volume of something over a period.
-
-## how to use
-
-Use it in alarms like this:
-
-```
- alarm: my_alarm
-    on: my_chart
-lookup: sum -1m unaligned of my_dimension
-  warn: $this > 1000
-```
-
-`sum` 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=sum` in the URL.
-
-## Examples
-
