Amazon CloudWatch query alarms now support monitoring metrics individually

Amazon CloudWatch now allows you to monitor multiple individual metrics via a single alarm. By dynamically including metrics to monitor via a query, this new capability eliminates the need to manually manage separate alarms for dynamic resource fleets.

As customers rely more on autonomous teams and autoscaled resources, they face a choice between maintenance-free aggregated monitoring and the operational cost of maintaining per-resource alarming. Alarms that evaluate multiple metrics provide granular monitoring with individual actions through an alarm that automatically adjusts in real time as resources get created or deleted. This reduces operational efforts, allowing customers to focus on the value of their observability while ensuring no resources go unmonitored.

Monitoring multiple metrics with a single alarm is now available in all commercial AWS regions, the AWS GovCloud (US) Regions, and the China Regions.

To start alarming on multiple metrics, create an alarm on a Metrics Insights (SQL) metrics query using GROUP BY and ORDER BY conditions. The alarm automatically updates the query results with each evaluation, and matches corresponding metrics as resources change. You can configure alarms through the CloudWatch console, AWS CLI, CloudFormation, or CDK. Metrics Insights query alarms’ pricing applies, see CloudWatch pricing for details.
