–Absolute — Compares the values directly with the thresholds at the end of the sampling interval.
•Rising Threshold — Displays the rising counter value that triggers the rising threshold alarm. The rising
threshold is presented on top of the graph bars. Each monitored variable is designated a color.
•Rising Event — Displays the mechanism in which the alarms are reported. The possible field values are:
–LOG — Indicates there is not a saving mechanism for either the device or in the management system. If
the device is not reset, the entry remains in the Log Table.
–TRAP — Indicates that an SNMP trap is generated, and sent via the Trap mechanism. The Trap can also
be saved using the Trap mechanism.
–Both — Indicates that both the Log and Trap mechanism are used to report alarms.
•Falling Threshold — Displays the falling counter value that triggers the falling threshold alarm. The falling
threshold is graphically presented on top of the graph bars. Each monitored variable is designated a color.
•Falling Event — Displays the mechanism in which the alarms are reported.
•Startup Alarm — Displays the trigger that activates the alarm generation. Rising is defined by crossing the
threshold from a low-value threshold to a higher-value threshold.
•Interval (sec) — Defines the alarm interval time in seconds.
•Owner — Displays the device or user that defined the alarm.
