Specify How the Alarm is Triggered (Event-based)
You can specify the events, states, or conditions that trigger the alarm in the Triggers tab of the Alarm
Settings dialog box. The options you choose under the General tab of the Alarm Settings dialog box
determine the options available under the Triggers tab. An alarm definition must contain at least one trigger
before it can be saved.

Open the Triggers tab of the Alarm Settings dialog box.

Specify Alarm Tolerance and Frequency
You can use reporting to apply a tolerance range for the alarm triggers. This can help you distinguish
temporary problems from more serious, chronic ones. The Reporting settings allow you to specify the
amount a condition or state must exceed the trigger value before the alarm triggers.
Reporting settings include Range and Frequency. Range is the threshold the monitored condition or state
must exceed the specified trigger limit for the alarm to trigger. Frequency is the length of time between each
re-triggering for as long as the condition or state exists. The Reporting tab is disabled for alarms with event-
based triggers.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Open the Reporting tab of the Alarm Settings dialog box.
Required Privilege: Alarms.Create alarm or Alarms.Modify alarm
Procedure
1 (Optional) Specify how far over, or under, trigger limits the conditions must exceed before the alarm is
triggered again.
