## Viewing instance status and recommendations

* **Note**\
  Amazon RDS also uses another status called *maintenance status*, which is shown in the **Maintenance** column of the Amazon RDS console. This value indicates the status of any maintenance patches that need to be applied to a DB instance. Maintenance status is independent of DB instance status. For more information about maintenance status, see [Applying updates for a DB instance](https://github.com/kevinslin/aws-reference-notes/blob/main/services/amazon_rds/USER_UpgradeDBInstance.Maintenance.md#USER_UpgradeDBInstance.OSUpgrades).

## Analyzing performance with DevOps Guru for RDS

* **Important**\
  We recommend that you test any changes on a test instance before modifying a production instance. In this way, you understand the impact of the change.
