Database Autonomy Service (DAS) allows you to globally customize monitoring dashboards. If enterprise users want to manage multiple instances, they can customize multi-instance monitoring dashboards to correlate, compare, and view multiple instances and metrics for daily O&M.
- The database instance to be monitored is provided by MySQL, MongoDB, Redis, or the ApsaraDB PolarDB MySQL-compatible edition.
- The database instance that you want to manage is connected to DAS and is in the Accessed state. For more information about how to connect a database instance to DAS, see the following topics:
DAS monitoring dashboards support the following metrics. In this example, MySQL is selected.
