After you acknowledge an alarm in the vSphere Web Client, its alarm actions are discontinued. Alarms are not cleared, or reset when acknowledged.
About this task
Acknowledging an alarm lets other users know that you are taking ownership of the issue. For example, a host has an alarm set to monitor CPU usage. It 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 the problem is being addressed, and to prevent the alarm from sending more email messages. The alarm, however, is still visible in the system.
