Acknowledge Triggered Alarms
After you acknowledge an alarm in the vSphere Web Client, 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.
