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 3-2experienced 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.

For more information about the relationship between rising and falling alarms and the

TIP hysteresis function that controls the generation of alarm events, see How Rising and Falling Thresholds Work, on page 3-27.

Time Indicates the date and time of each event occurrence.
