For example, if the wfCctOptsCngcCfgQp1Threshold variable has a value of 120,

the agent generates an event message similar to the following:

#1:08/27/96 10:53:20.802 INFO SLOT 2 STA CODE: 6

Object 1.3.6.1.4.1.18.3.5.1.4.10.1.24 with value = 120 units/ hour

is > low threshold.

You can, however, identify objects more easily by configuring the software to

report the object name rather than the OID in the event message. To configure the

software to report the object name in the event message, use the Threshold Label

parameter (see page A-15).

For example, if you set the Threshold Label parameter to

wfCctOptsCngcCfgQp1Threshold

, the agent generates an event message similar

to the following:

#1:08/27/96 10:53:20.802 INFO SLOT 2 STA CODE: 6

Object wfCctOptsCngcCfgQp1Threshold with value = 120 units/ hour is

> low threshold.

State of a Threshold

If the collision rate stays above a threshold for an extended period of time, the

agent continues to generate a new event every 5 seconds. You can specify the

maximum number of event messages you want the agent to generate before it

changes the threshold’s state to held.

When the threshold is in a held state, the agent does not generate new events

unless the statistic exceeds the threshold at a different level. If the statistic does

not exceed any threshold for a specified number of polling periods, the agent no

longer considers the threshold held.

Memory Considerations

Polling statistics to determine whether they have reached a threshold and reporting

events when variables exceed thresholds require router processing capacity. When

you set many thresholds and use shorter polling intervals, the router performance

will probably decline.
