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.

Before you begin

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

About this task

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.

Procedure

  1. (Optional) : Specify how far over, or under, trigger limits the conditions must exceed before the alarm is triggered again.
  2. (Optional) : Select a Frequency.

    The frequency sets the time period during which a triggered alarm is not reported again. When the time period has elapsed, the alarm will report again if the condition or state is still true.

What to do next

Optionally specify alarm actions, or click OK to save your changes and exit the dialog box.
