Figure 52: The Alarm Process
There are two methods to evaluate a statistic in order to determine when to generate an event: delta and
absolute.
For most statistics, such as line errors, it is appropriate to generate an alarm when a rate is exceeded. The
alarm defaults to the delta measurement method, which examines changes in a statistic at the end of each
measurement period.
It may be desirable to alarm when the total, or absolute, number of events crosses a threshold. In this case, set
the measurement period type to absolute.
The following sections describe how to configure and manage RMON alarms:
• Section 3.10.2.1, “Viewing a List of RMON Alarms”
• Section 3.10.2.2, “Adding an RMON Alarm”
• Section 3.10.2.3, “Deleting an RMON Alarm”
