/**
*
* Describes an adjustment based on the difference between the value of
* the aggregated CloudWatch metric and the breach threshold that you've
* defined for the alarm.
*
*
* For the following examples, suppose that you have an alarm with a
* breach threshold of 50:
*
*
*
* -
* If you want the adjustment to be triggered when the metric is greater
* than or equal to 50 and less than 60, specify a lower bound of 0 and
* an upper bound of 10.
*
*
* -
* If you want the adjustment to be triggered when the metric is greater
* than 40 and less than or equal to 50, specify a lower bound of -10 and
* an upper bound of 0.
*
*
*
*
*
* There are a few rules for the step adjustments for your step policy:
*
*
*
* -
* The ranges of your step adjustments can't overlap or have a gap.
*
*
* -
* At most one step adjustment can have a null lower bound. If one step
* adjustment has a negative lower bound, then there must be a step
* adjustment with a null lower bound.
*
*
* -
* At most one step adjustment can have a null upper bound. If one step
* adjustment has a positive upper bound, then there must be a step
* adjustment with a null upper bound.
*
*
* -
* The upper and lower bound can't be null in the same step adjustment.
