• Interval
Indicates the interval in seconds for sampling and comparing the rising and
falling threshold. The range is from 1 to 2^31-1.
• Variable
Indicates the particular variable to be sampled; the possible variables are:
InOctets: The total number of octets received on the interface, including
framing characters.
InUcastPkts: The number of uni-cast packets delivered to a higher-layer
protocol.
InNUcastPkts: The number of broadcast and multi-cast packets delivered to
a higher-layer protocol.
InDiscards: The number of inbound packets that are discarded even the
packets are normal.
InErrors: The number of inbound packets that contains errors preventing
them from being deliverable to a higher-layer protocol.
InUnknownProtos: the number of the inbound packets that is discarded
because of the unknown or un-support protocol.
OutOctets: The number of octets transmitted out of the interface, including
framing characters.
OutUcastPkts: The number of uni-cast packets that requests to transmit.
OutNUcastPkts: The number of broadcast and multi-cast packets that
requests to transmit.
OutDiscards: The number of outbound packets that is discarded even the
packets are normal.
OutErrors: The number of outbound packets that could not be transmitted
because of errors.
OutQLen: The length of the output packet queue (in packets).
• Sample Type
The method of sampling the selected variable and calculating the value to be
compared against the thresholds; possible sample types are:
Absolute: Get the sample directly.
Delta: Calculate the difference between samples (default).
• Value
The value of the statistic during the last sampling period.
• Startup Alarm
The method of sampling the selected variable and calculating the value to be
compared against the thresholds; possible sample types are:
RisingTrigger alarm when the first value is larger than the rising threshold.
FallingTrigger alarm when the first value is less than the falling threshold.
RisingOrFallingTrigger alarm when the first value is larger than the rising
threshold or less than the falling threshold (default).
• Rising Threshold
Rising threshold value (-2147483648-2147483647).
• Rising Index
Rising event index (1-65535).
• Falling Threshold
Falling threshold value (-2147483648-2147483647)
