MetricCharacteristics

This object includes parameters that you can use to provide information to CloudWatch to help it build more accurate anomaly detection models.

PeriodicSpikes

Set this parameter to true if values for this metric consistently include spikes that should not be considered to be anomalies. With this set to true, CloudWatch will expect to see spikes that occurred consistently during the model training period, and won't flag future similar spikes as anomalies.
