Enable and Disable Alarm Actions
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.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Required privilege: Alarm.Disable Alarm Action
Procedure
n
To disable alarm actions, right-click on the inventory object and select Alarm > Disable Alarm Actions.
n
To enable alarm actions, right click on the inventory object and select Alarm > Enable Alarm Actions.
Acknowledge Triggered Alarms
After an alarm is acknowledged, its alarm actions are discontinued. Alarms are neither cleared, nor reset
when acknowledged.
Acknowledging an alarm lets other users know that you are taking ownership of the issue. For example, a
host has an alarm set on it that monitors CPU usage and that sends an email to an administrator when the
alarm is triggered. The host CPU usage spikes, triggering the alarm which sends an email to the host's
administrator. The administrator acknowledges the triggered alarm to let other administrators know he is
working on the problem, and to prevent the alarm from sending more email messages. The alarm, however,
is still visible in the system.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Required privilege: Alarm.Alarm Acknowledge
Procedure
1 Navigate to the inventory panel.
2 If the status panel is not available, select View > Status Bar to view the status pane.
3 In the status bar, click Alarms to display the Triggered Alarms panel.
4 Right-click the alarm and select Acknowledge Alarm.
To acknowledge multiple alarms at one time, Shift+click each alarm to select it, right-click the selection,
and select Acknowledge Alarm.
Reset Triggered Event Alarms
An alarm triggered by an event might not reset to a normal state if vCenter Server does not retrieve the
event that identifies the normal condition. In such cases, reset the alarm manually to return it to a normal
state.
Prerequisites
Launch the vSphere Client and log in to a vCenter Server system.
Required privilege: Alarm.Set Alarm Status
