You can monitor inventory objects by setting alarms on them. Setting an alarm involves selecting the type of inventory object to monitor, defining when and for how long the alarm will trigger, and defining actions that will be performed as a result of the alarm being triggered. You define alarms in the Alarm Settings dialog box.

Ensure that you have connected to a vCenter Server system by using the vSphere Client.

Required Privilege: Alarms.Create alarm or Alarms.Modify alarm

You create and modify alarms in the Alarm Settings dialog box. You can view alarm settings from any object, but you can modify settings only through the object on which the alarm is defined.

General settings include alarm Name, Description, and Type. You can also enable and disable the alarm in the General settings tab. Specifying the alarm type includes selecting the type of inventory object and the type of activity (events, or conditions and states) that you want to monitor. The options in the Triggers tab change depending on the type of activity you choose to monitor.

You can specify the events, states, or conditions that triggers 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.

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.

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.

You can specify actions that the system performs when the alarm is triggered or changes status. You can enable and disable alarms and alarm actions independently of each other.

You can disable alarm actions on any inventory object. Disabling alarm actions is not the same as disabling an alarm, nor is it the same as acknowledging an alarm. When alarm actions are disabled, the alarm can still be triggered but its associated actions will not be performed. You might want to disable alarm actions when, for example, you plan on putting a host into maintenance mode. When you disable alarm actions on a selected inventory object, all actions for all alarms are disabled on that object. You cannot disable a subset of alarm actions. Alarm actions will continue on the child objects.
