Alarm Configuration
Viewing the Basic Alarm Log
If you have selected the “log” response for an alarm, and that alarm’s rising
and/or falling threshold has been crossed, the Basic Alarms application will
create a log of alarm occurrences. If a threshold has been crossed, it will be
preceded in the interface list box display by a double greater-than sign (>>).
Clicking to select an interface which is so marked will activate the View Log
button; selecting the View Log button will launch the appropriate Basic Alarm
Log,
Figure 3-2 . (Note that selecting more than one interface — even if all selected
interfaces have experienced alarm conditions — will deactivate the View Log
button; you can only view a single alarm log at a time.)
Figure 3-2. Basic Alarm Log
The top portion of the Basic Alarm Log window contains the device information
boxes, as well as the Port Number assigned to the interface that experienced the
alarm condition and the type of alarm that was triggered; the remainder of the
window contains the following information about each alarm occurrence:
Index This index number uniquely identifies each occurrence of
a rising or falling event. Note that, since the alarm whose
log is displayed in
Figure 3-2 experienced both rising and
falling alarms, there are two sets of event indices: one
which identifies each instance of the rising alarm, and
one which identifies each instance of the falling alarm.
Time Indicates the date and time of each event occurrence.
TIP
For more information about the relationship between rising and falling alarms and the
hysteresis function that controls the generation of alarm events, see
How Rising and
Falling Thresholds Work , on page 3-27 .
