Delta — Subtracts the last sampled value from the current value.
■
The difference in the values is compared to the threshold.
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.
Rising Alarm — Defines rising as crossing the threshold from a
■
low-value threshold to a higher-value threshold.
Falling Alarm — Defines falling as the falling counter value that
■
triggers the falling threshold alarm.
Rising and Falling Alarm — Both alarms are triggered
■
Interval — Defines the alarm interval time in seconds.
■
Owner — Displays the device or user that defined the alarm.
