The vSphere Client uses visual indicators to denote whether alarm actions are enabled or disabled.

When an object is selected in the inventory, you can identify its disabled alarm actions in the following areas of the vSphere user interface:

In the General pane of the object's Summary tab.

In the Alarm Actions Disabled pane of the Alarms tab.

In the Alarm Actions column of the object's child object tabs. For example, if you select a host in the inventory, the Virtual Machines tab displays whether alarm actions are enabled or disabled for each virtual machine on the host.
