Metrics with data points requirements
For metrics without an obvious default threshold to alarm on, Application Insights waits until the metric has enough data points to predict a reasonable threshold to alarm on. The metric data points requirement that CloudWatch Application Insights checks before an alarm is created are:
-
The metric has at least 100 data points from the past 15 to the past 2 days.
-
The metric has at least 100 data points from the last day.
The following metrics follow these data points requirements. Note that CloudWatch agent metrics require up to one hour to create alarms.
