number
• number —The alarm index. (Range: 1–65535)
•
variable —A fully qualified SNMP object identifier that resolves to a
particular instance of a MIB object.
•
interval —The interval in seconds over which the data is sampled and
compared with the rising and falling thresholds. (Range: 1– 2147483647)
•
rising-threshold value —Rising Threshold value. (Range: -2147483648 –
2147483647)
•
falling-threshold value —Falling Threshold value. (Range: -2147483648 –
2147483647)
•
event-number —The index of the Event that is used when a rising or
falling threshold is crossed. (Range: 1- 65535)
•
delta —The sampling method for the selected variable and calculating the
value to be compared against the thresholds. 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.
•
absolute —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.
•
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 rising-threshold, 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 falling-threshold, and
direction is equal to falling or rising-falling, then a single falling alarm is
generated.
•
owner string —Enter a name that specifies who configured this alarm. If
unspecified, the name is an empty string.
