Alarms Generated on vManage NMS

The table below lists the alarms that the vManage NMS software generates. The software generates alarms when a state or condition changes, such as when a software component starts, transitions from down to up, or transitions from up to down. The severity indicates the seriousness of the alarm. When you you create email notifications, the severity that you configure in the notification determines which alarms you can receive email notifications about.
