Example 11 - Alarming with composite alarms

Composite alarms can combine any type of CloudWatch alarm. Metric alarms are billed based on the number of metrics per alarm, while composite alarms are billed per alarm unit. One composite alarm costs ￥3.480 per month, regardless of the number of metric alarms it combines.

If you create one composite alarm that combines four standard resolution metric alarms, your monthly bill is calculated as follows:

Four standard resolution alarms = ￥0.622 per alarm metric * 4 = ￥2.488 per month

One composite alarm = ￥3.480 per month

Monthly CloudWatch charges = ￥2.488 + ￥3.480 = ￥5.968 per month
