The intention of this documentation is to provide the building blocks to create critical CloudWatch alarms which are fit for onboarding to Incident Detection and Response. It contains specific alarm best practices for AWS Services.
Overview
Here we have included Alarm Best Practices for Amazon Aurora Databases part of Relational Database Service (RDS) that Incident Detection and Response (IDR) customers can refer to. They can use these as a starting point in creating alarms fit to be onboarded to IDR. There are also AWS recommended alarms available, which customers may make use of.
The CloudWatch alarm best practices provided on this page are intended solely as general guidelines to assist you in configuring alarms for the Incident Detection and Response service. The final selection, configuration, and implementation of CloudWatch alarms should be tailored to the unique requirements of your environment, workloads, and operational needs. The recommendations we provide do not guarantee comprehensive coverage or detection of all issues, incidents, or outages. For more information on detailed configuration, we recommend consulting with your technical team.
