index
•
index
— The alarm index. (Range: 1–65535)
•
variable
— A fully qualified SNMP object identifier that resolves to a
particular instance of an MIB object.
•
interval
— The interval in seconds over which the data is sampled and
compared with the rising and falling thresholds. (Range: 1–4294967295)
•
rthreshold
— Rising Threshold. (Range: 0–4294967295)
•
fthreshold
— Falling Threshold. (Range: 0–4294967295)
•
revent
— The index of the Event that is used when a rising threshold is
crossed. (Range: 1- 65535)
•
fevent

(Range: 1- 65535)
•
type
type
— The sampling method for the selected variable and
calculating the value to be compared against the thresholds. If the method
is
absolute
, the value of the selected variable is compared directly with the
thresholds at the end of the sampling interval. If the method is
delta
, the
selected variable value at the last sample is subtracted from the current
value, and the difference compared with the thresholds.
•
startup
direction
— The alarm that may be sent when this entry is first set
to valid. If the first sample (after this entry becomes valid) is greater than
or equal to the
rthreshold
, and
direction
is equal to
rising
or
rising-falling
,
then a single rising alarm is generated. If the first sample (after this entry
becomes valid) is less than or equal to the
fthreshold
, and
direction
is
equal to
falling
or
rising-falling
, then a single falling alarm is generated.
•
owner
name
— Enter a name that specifies who configured this alarm. If
unspecified, the name is an empty string.
