Prerequisites

You have created a file system. For more information, see Create a file system.
You have activated CloudMonitor.

Set up alert rules to receive notifications when capacity exceeds a specified threshold, allowing you to quickly respond to and handle exceptions. For more information, see Configure Basic Alert Rules.
Create application groups for multiple file systems to manage their alert rules and monitoring data from a single location, which helps reduce management overhead. For more information, see Create Application Groups.
