Amazon Aurora DB Monitoring
Amazon Aurora DB - An Overview
Amazon Aurora is a relational database engine from Amazon Web Services, available as part of the Amazon Relational Database Service (RDS). Being MySQL and PostgreSQL - compatible and built for the cloud, Amazon Aurora provides security, availability, and reliability with the simplicity of open source databases.

Monitored Parameters
Go to the Monitors Category View by clicking the Monitors tab. Click on RDS in the Amazon Instances under the Cloud Apps Table. Displayed is the bulk configuration view distributed into three tabs:
- Availability tab gives the Availability history for the past 24 hours or 30 days.
- Performance tab gives the Health Status and events for the past 24 hours or 30 days.
- List view enables you to perform bulk admin configurations.
Click on the monitor name to see all the Amazon Aurora Database metrics listed under the following tabs:
Note: Applications Manager's AWS RDS monitor supports all engine types. However, the supported metrics vary based on the DB Engine types like 'Aurora PgSQL', 'Aurora MySQL' and 'Other engine types' (MySQL, MariaDB, PostgreSQL, Oracle, SQL Server, etc.). Refer to the AWS RDS supported Database Engines to know more.
