RMON Alarm Page
The RMON Alarm page contains the following fields:
Alarm Entry—Indicates a specific alarm.
l
Counter Name—Indicates the selected RMON counter.
l
Counter Value—Indicates the value of the RMON counter.
l
Sample Type—Specifies the sampling method for the selected variable and compares the value against the thresholds. The possible field values are:
l
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—The rising counter value that triggers the rising threshold alarm.
l
Rising/Falling Event—The mechanism that reports the alarms: LOGed or TRAPed or a combination of both. When LOG is selected, there is no saving
l
mechanism either in the device or in the management system. However, if the device is not being reset, it remains in the device LOG table. If TRAP is
selected, a TRAP via SNMP is generated and reported via the TRAP's general mechanism. The TRAP can be saved using the same mechanism.
Falling Threshold—The falling counter value that triggers the falling threshold alarm.
l
NOTE:
The Rising and Falling thresholds are graphically presented on top of the graph bars. Each monitored variable has a designated color.
Startup Alarm—The trigger that activates the alarm. Rising is defined by crossing the threshold from a low value threshold to a higher value threshold.
