By default, this test reports metrics for each active DB instance on the cloud. This is why, this flag is set to DBInstanceIdentifier, by default. If needed, you can pick either of the following options from this drop-down:
- DatabaseClass: The computation and memory capacity of a DB instance is determined by its DB instance class. If you select this option, then this test will report metrics for each DB instance class. In other words, eG will aggregate metrics for all databases that belong to a DB intance class, and will present these metrics at the macro class-level.
- EngineName: Each DB instance runs a DB engine. Amazon RDS currently supports the MySQL, MariaDB, PostgreSQL, Oracle, and Microsoft SQL Server DB engines. Each DB engine has its own supported features, and each version of a DB engine may include specific features. If you select this option, then this test will report metrics for every DB engine. In this case, eG will aggregate metrics for all databases using a particular engine, and will present these metrics at the macro engine-level.
