CloudWatch Alarms

CloudWatch Alarms are a unified way to trigger alarms for system events in AWS.

You can create both metric alarms and composite alarms in CloudWatch.

A metric alarm watches a single CloudWatch metric or the result of a math expression based on CloudWatch metrics.

A composite alarm includes a rule expression that takes into account the alarm states of other alarms that you have created.

Commandeer allows you to view all of your CloudWatch Alarms and easily track their occurrences.
