Scenarios

You can set alarm rules for GaussDB(for MySQL) to customize the monitored objects and notification policies and stay aware of the GaussDB(for MySQL) operating status.

The GaussDB(for MySQL) alarm rules include alarm rule names, services, dimensions, monitored objects, metrics, alarm thresholds, monitoring period, and whether to send notifications.
