CustomizedLoadMetricSpecification class
Represents a CloudWatch metric of your choosing that can be used for predictive scaling.
For predictive scaling to work with a customized load metric specification,
AWS Auto Scaling needs access to the Sum and
Average statistics that CloudWatch computes from metric data.
Statistics are calculations used to aggregate data over specified time
periods.
When you choose a load metric, make sure that the required Sum
and Average statistics for your metric are available in
CloudWatch and that they provide relevant data for predictive scaling. The
Sum statistic must represent the total load on the resource,
and the Average statistic must represent the average load per
capacity unit of the resource. For example, there is a metric that counts
the number of requests processed by your Auto Scaling group. If the
Sum statistic represents the total request count processed by
the group, then the Average statistic for the specified metric
must represent the average request count processed by each instance of the
group.
For information about terminology, available metrics, or how to publish new metrics, see Amazon CloudWatch Concepts in the Amazon CloudWatch User Guide.
