Based on the root cause of the problem, and the solutions that you used to fix the problem, you can create a new alert definition for VMware Aria Operations to alert you. When the alert is triggered on your host system, VMware Aria Operations alerts you and provides recommendations on how to solve the problem.

To alert you before your host systems experience critical capacity problems, and have VMware Aria Operations notify you of problems in advance, you create alert definitions, and add symptom definitions to the alert definition.
