sampling
-
interval
: Sets the sampling interval in the range of 5 to 65535 seconds.
absolute
: Specifies absolute sampling. RMON compares the value of the variable with the rising and
falling thresholds at the end of the sampling interval.
delta
: Specifies delta sampling. RMON subtracts the value of the variable at the previous sample
from the current value, and then compares the difference with the rising and falling thresholds.
startup-alarm
: Specifies alarms that can be generated when the alarm entry becomes valid. If you
do not specify an alarm, RMON can generate a rising alarm or a falling alarm depending on the first
sample.
rising
: Generates a rising alarm if the first sample after the entry becomes valid is greater than or
equal to the rising threshold.
falling
: Generates a falling alarm if the first sample after the entry becomes valid is less than or equal
to the rising threshold.
rising-falling
: Generates a rising alarm if the first sample crosses the rising threshold, or generates
a falling alarm if the first sample crosses the falling threshold.
rising-threshold
threshold
-
value1
event
-
entry1
: Sets the rising threshold. The
threshold-value1
argument represents the rising threshold in the range of –2147483648 to +2147483647. The
event-entry1
argument represents the index of the event that is triggered when the rising threshold is
crossed. The value range for the
event-entry1
argument is 0 to 65535. If 0 is specified, the alarm
does not trigger any event.
falling-threshold
threshold
-
value2
event
-
entry2
: Sets the falling threshold. The
threshold
-
value2
argument represents the falling threshold in the range of –2147483648 to +2147483647. The
event
-
entry2
argument represents the index of the event that is triggered when the falling threshold
is crossed. The value range for the
event
-
entry2
argument
is 0 to 65535. If 0 is specified, the alarm
does not trigger any event.
owner
text
: Specifies the entry owner, a case-sensitive string of 1 to 127 characters.
Usage guidelines
Before you create RMON alarm entries, you must enable the SNMP agent.
You can create a maximum of 60 entries in the RMON alarm table.
Each alarm entry must have a unique alarm variable, sampling interval, sample type, rising threshold,
or falling threshold. You cannot create an alarm entry if all these parameters for the entry are the
same as an existing entry.
To trigger the event associated with an alarm condition, you must create the event with the
rmon
event
command.
RMON samples the monitored alarm variable at the specified sampling interval, compares the
sampled value with the predefined thresholds, and does one of the following:
•
Triggers the event associated with the rising alarm if the sampled value is equal to or greater
than the rising threshold.
