Symptoms are conditions that indicate problems in your environment. You can define symptoms in VMware Aria Operations and add them to alert definitions so that you know when a problem occurs with your monitored objects.

To define symptoms, from the left menu, click Operations > Configurations, and then click the Symptom Definitions tile. .Symptom definitions evaluate conditions in your environment that, if the conditions become true, an alert is generated.
