Easy-to-use CDK constructs for monitoring your AWS infrastructure.

* Easily add commonly-used alarms using predefined properties
* Generate concise Cloudwatch dashboards that indicate your alarms
* Extend the library with your own extensions or custom metrics
* Consume the library in multiple languages (see below)
