Alarms
Alarms are activated by status changes in network devices. When MegaVision detects a
change in a device, it generates an alarm. A beep is sounded and the alarm is recorded in the
Alarm Log, indicating the date and time, the device in which it occurred, the severity, and a
short description of the reason for the alarm. An alarm is also reflected in the device icon—
the icon color changes according to the severity of the alarm. Alarms have four severity
levels, each represented by a different color: Critical, Warning, Normal, and Informational.
Please note that a lot of alarms are actually generated by SNMP Traps, which are sent by
different network devices.
Alarm Notifications
In addition to an audible sound notifying you of an alarm condition, the color of a device icon
corresponds to the latest alarm with the highest severity. When an event received cancels
any previously received alarm, and the color of the icon is updated to reflect the new status of
the device.
Alarm Severity Color
Informational Purple
Normal Green
Critical Red
Unknown Gray
Alarm notifications may be received via e-Mail as well (see below).
