Alarm Configuration
4-14 Advanced Alarm Configuration
The fields in the Events Watch display include:
Index This is a number that uniquely identifies an entry in the event
table; an index number is assigned when an event is created.
These numbers are extremely important, as they are the means
by which an event is associated with an alarm or a packet
capture filter. As with alarms, these index numbers are
user-defined and can be assigned according to any indexing
scheme that works for you. Index numbers are permanently
assigned to their associated events; however, numbers made
available by the deletion of existing events can be assigned to
new events, as needed. Note that indices 2000 to 4999 are
reserved and unavailable.
LastTime Indicates the last time this event was triggered. Note that this
information is static once it is displayed, and the LastTime
field will not be updated unless you close, then open, the
Advanced Alarms/Events window, or click on the Refresh
button.
Type Indicates the type of response that will be generated if the
event is triggered: log, trap, or log & trap. A type of “none”
indicates that occurrences of the event will not be logged and
no trap will be sent; however, note that this field does not
indicate whether or not there are any actions associated with
the selected event.
Description This is a user-defined text description used to identify the event
and/or the alarm or packet capture that triggers it.
The Event Log button at the bottom of the screen provides access to the log which lists
the occurrences of an event.
Note that the information provided in this screen is static once it is displayed; for updated
information, click on the Refresh button. Adding or modifying an event automatically
updates the list.
Creating and Editing an Advanced Alarm
The Create/Edit Alarms window ( Figure 4-4 on page 4-15 ) allows you to both create new
alarms and edit existing ones. When you click on the Create/Edit button in the Alarms
Watch list, the Create/Edit Alarms window will display the parameters of the alarm which
is currently highlighted in the list. (If no alarms have yet been configured, a set of default
parameters will be displayed.) All of these parameters are editable: to change an existing
alarm, edit any parameter except the Index value; to create an entirely new alarm, simply
assign a new Index number. The ability to assign index numbers allows you to quickly and
easily create a number of similar alarms without having to close, then re-open the window
or re-assign every parameter.
