About the Alarms Page

To access this page, select Monitor > Alerts & Alarms > Alarms.

Use the Alarms page to view system-generated alarms. Alarms notify you of conditions that might prevent the device from operating normally. Alarm conditions for a system are preset and are based on the fault monitoring and performance monitoring (FMPM) being performed on a device. For example, conditions such as hardware issues, drop in throughput and latency of data, temperature variations, and capacity optimization issues automatically trigger an alarm.


To generate alarms correctly, ensure that CSO and the devices are NTP enabled, and in sync. The time set on CSO must match with the time set on the devices.

The difference between alerts and alarms lies in the type of events that are being monitored. An alert is used to notify administrators about significant events within the system. For example, when a predefined network traffic condition is met. For more information about alerts, see Alerts Overview.
