Site Recovery Manager adds alarms to the alarms that vCenter Server supports. You can configure Site Recovery Manager alarms to send an email notification, send an SNMP trap, or to run a script on the vCenter Server host.
The Alarms tab in the Site Recovery Manager interface lists all of the Site Recovery Manager alarms. You can edit the settings for each alarm to specify the action for Site Recovery Manager to take when an event triggers the alarm. By default, none of the Site Recovery Manager alarms act until you configure the alarm.
Prerequisites
For alarms to send email notifications, you must configure the Mail settings in the vCenter Server Settings menu.
