This modules finds the incremental sum of a period, which last value - first value.

The result may be positive (rising) or negative (falling) depending on the first and last values.

how to use

Use it in alarms like this:

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

incremental_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.
