Alarm Table

The Alarm Table window displays the following parameters:

• Alarm Interval — The value used is Time (in seconds). The default is the value specified in the graph Sample Time parameter. Modifications are done by changing the Sample Time parameters. Sample Time settings are as follows:

• Delta — Counter is reset

• Absolute — ROS monitors the counter for the defined interval

• Alarm Variable — The selected MIB variable.

• Alarm Port  —  Port to which the alarm is configured.

• Sample Time — There are two Sample Time settings:

• Delta (Default) — The counter is reset at the times defined by the interval.

• Absolute — The counter is not reset until the counter is overflowed. If the counter overflows, the threshold is set according to the aggregated counter results.

• Value — Value reached after the alarm was triggered.

• Startup Alarm — The trigger that activates the alarm generation. The trigger can be a Rising alarm, Falling alarm, or a combination of both Rising and Falling. Rising is defined by crossing the threshold from low value threshold to a higher value threshold.

• Rising Threshold — The rising counter value that triggers the Rising Threshold alarm.

• Falling Threshold — The falling counter value that triggers the Falling Threshold alarm.

Note: The Rising and Falling threshold are graphically presented on top of the graph bars. Each monitored variable is designated a color.

• Rising and Falling Events — The mechanism in which the alarms will be reported. Either LOGed or TRAPed or combination of both. When LOG is selected, there is no saving mechanism either in the device or in the management system. However, if the device is not being reset, it will remain in the device LOG table. If TRAP is selected, a TRAP via SNMP is generated and reported via the TRAPs general mechanism. The TRAP can be saved using the same mechanism (refer to Trap Monitor).
