Measures reported by AWSRDSEventsTest

Amazon RDS (Relational Database Service) generates a significant number of events in categories that you can subscribe to using the Amazon RDS Console, AWS CLI, or the API. Each category applies to a source type.

Administrators may want to track these events, particularly problem events (eg., failure events, low storage events etc.), so that they instantly detect and promptly resolve issues in the AWS RDS service. This is where the AWS RDS Events test helps!

This test reports the count of events of different categories that Amazon RDS periodically generates. Alerts are sent out if problem events are captured. Detailed diagnostics describe the problem events, so that you can quickly tell where and why the problem occurred. This way, the test helps in rapidly identifying and efficiently troubleshooting RDS-related issues.

Output of the test: One set of results for each type of event source in each region of the AWS cloud - the source type can be a DB instance / DB parameter group / DB security group / DB snapshot / RDS proxy.

First-level descriptor: AWS EC2 region name

Second-level descriptor: Event source type

Note:

If Amazon RDS does not generate any event, then this test will not be able to report any metrics. To handle such situations, this test supports a Summary descriptor. As long as the Amazon RDS service generates at least one event, the Summary descriptor will not even be visible in the eG monitoring console. On the contrary, if the service does not even generate a single event, then this test will report measures for the Summary descriptor alone. In this case, the test will report the value 0 for the Creation events, Availability events, Failure events, and Deletion events measures of the Summary descriptor. Other measures will not appear in the eG monitoring console.
