Alarm Conﬁguration

Interval	Indicates the amount of time, in seconds, over which the
	selected variable will be sampled. At the end of the
	interval, the sample value is compared to both the rising
	and falling thresholds conÞgured for the alarm.
Sample	Indicates whether the sample value to be compared to
	the thresholds is an absolute, or total value Ñ that is, the
	total value counted for the selected variable during the
	interval Ñ or a relative, or delta value Ñ the difference
	between the value counted during the current interval
	and the value counted during the previous interval.
LoThrshld	Indicates the set value for the low, or falling threshold.
Event #	Indicates the event index number that the falling
	threshold points to: this is the event that will be triggered
	if the falling threshold is met or crossed. If the value for
	this Þeld is zero, no event will be triggered.
HiThrshld	Indicates the set value for the high, or rising threshold.
Event #	Indicates the event index number that the rising
	threshold points to: the event that will be triggered if the
	rising threshold is met or crossed. If the value for this
	Þeld is zero, no event will be triggered.
Status	Indicates the status of the alarm: valid, invalid, or
	underCreation. An alarm that is invalid is not functional;
	it may be referring to a MIB component that is inactive
	(such as the Hosts component), not present, or
	unreachable, or it may have been deleted by software but
	not yet removed from memory at the device. An alarm
	that is underCreation is in the process of being
	conÞgured (possibly by another management station),
	and should not be modiÞed until its status is valid; if it
	never reaches valid status, it will eventually be removed.
Alarm Variable	Indicates the variable that is being watched. You can use
	the scroll bar, if necessary, to view the complete name.

The Þelds in the Events Watch display include:

Index	This is a number that uniquely identiÞes 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 Þlter. As with alarms, these
	index numbers are user-deÞned and can be assigned
	according to any indexing scheme that works for you.
