As a Database Administrator, you can use the Diagnostics & Management features in the Oracle Cloud Infrastructure Database Management service to monitor HeatWave and External MySQL DB systems.

Database Management supports:

• HeatWave DB systems and clusters: DB systems and attached HeatWave clusters in the HeatWave service, which is a fully managed Oracle Cloud Infrastructure native service. Database Management is available at no additional cost for HeatWave and is automatically enabled for new DB systems and can be enabled in a single step for existing DB systems. You can use Database Management for the following DB system configurations:
  • Standalone: A single instance DB system.
  • High Availability: A three-instance DB system that contains one primary instance and two secondary (standby) instances, which guarantees if the primary instance fails, a standby instance takes over, with zero data loss and minimal downtime.
  Note
  
  Although you can enable and use Database Management for both Standalone and High Availability DB system configurations, Database Management only monitors the primary instance in the DB system. For example, if Database Management is enabled for a DB system with secondary instances, it will only monitor and display metrics for the primary instance in the DB system and the attached HeatWave cluster, if any, and not for the other instances.

  For more information, see Overview of HeatWave Service.

• External MySQL DB systems: DB systems deployed on premises and connected to a resource in the Database Management service. Using Database Management, you can create an Oracle Cloud Infrastructure resource that represents the External MySQL DB system within your tenancy, connect to it using a connector resource, and monitor it in Oracle Cloud Infrastructure. Database Management support for External MySQL DB systems is available through a non-metered subscription. For information, see Subscription for External MySQL DB System Support.

  For External MySQL DB systems, Database Management supports version 8.x and later. Currently, only Linux-based External MySQL DB systems are supported.

  Note
  
  To ensure consistency in terminology, "DB systems" is used across Database Management for HeatWave and External MySQL documentation. For External MySQL DB systems, it denotes the MySQL server instances, which contain one or more MySQL databases.

Database Management for HeatWave and External MySQL DB systems provides performance monitoring and diagnostic capabilities, which simplify the detection of performance issues and ensure a quick resolution of performance bottlenecks. It also provides performance management capabilities to proactively identify the root cause of SQL performance issues. Here are some of the important tasks you can perform using Database Management:

• Monitor the key performance and configuration metrics of your fleet of HeatWave and External MySQL DB systems.
• Monitor the metrics and configuration variables of a single HeatWave or External MySQL DB system.
• Use Performance Hub to monitor and troubleshoot SQL performance.
• Monitor the fleet of HeatWave clusters attached to HeatWave DB systems and the metrics of a single HeatWave cluster.
