Create a New Alert Definition
Based on the root cause of the problem, and the solutions that you used to x the problem, you can create a
new alert denition for vRealize Operations Manager to alert you. When the alert is triggered on your host
system, vRealize Operations Manager alerts you and provides recommendations on how to solve the
problem.
To alert you before your host systems experience critical capacity problems, and have
vRealize Operations Manager notify you of problems in advance, you create alert denitions, and add
symptom denitions to the alert denition.
