1 Alarms

The most common kind of alarm is a metric alarm which is an alarm linked to a Cloudwatch metric (though more sophisticated alarms are available). Alarms of this kind are typically configured to trigger after said metric exceeds a threshold in a given number of time periods.

Actions are associated with alarms and are dispatched once alarms reach ALARM state, a common example would be to send a notification to an SNS topic.

1.1 Example:

If you alarm on 4 out of 5 data points with a period of 1 minute, then:

  • datapointsToAlarm = 4
  • evaluationPeriods = 5
  • period = 1 minute

threshold is what determines whether a data point (calculated from the metric definition) is "bad" and contributes to the 4 out of 5 data points rule. See also:
