Parameters
oid oid : Specifies the OID of the monitored MIB variable, a string of 1 to 256 characters.
monitor-obj { get | next }: Specifies the SNMP operation used for sampling variable values. The get
keyword represents the SNMP get operation, and the next keyword represents the SNMP getNext
operation.
start-op start-op : Specifies the operator for comparing the sampled value with the start threshold.
The start threshold is crossed if the comparison result meets the condition. For keywords available
for the
start-op argument, see Table 56 .
start-val start-val : Specifies the start threshold to be compared with the sampled value. The start-val
argument can be any data type supported by SNMP, including numerals and character strings. The
CLI online help system displays the value range as character strings of 1 to 512 characters. If the
threshold value contains spaces, you must enclose the value in quotation marks (" ").
restart-op op : Specifies the operator for comparing the sampled value with the restart threshold.
The restart threshold is crossed if the comparison result meets the condition. For keywords available
for the
start-op argument, see Table 56 .
restart-op restart-val : Specifies the restart threshold to be compared with the sampled value. The
restart-val argument can be any data type supported by SNMP, including numerals and character
strings. The CLI online help system displays the value range as character strings of 1 to 512
characters. If the threshold value contains spaces, you must enclose the value in quotation marks ("
").
interval interval : Specifies the sampling interval in the range of 1 to 4294967295 seconds. The
default is 300 seconds.
Usage guidelines
Use SNMP event monitor policy to monitor value changes of MIB variables.
You can configure only one event for a monitor policy. If the monitor policy already contains an event,
the new event replaces the old event.
EAA executes an SNMP event monitor policy when the monitored MIB variable's value crosses the
start threshold in the following situations:
•
The monitored variable's value crosses the start threshold for the first time.
•
The monitored variable's value crosses the start threshold each time after it crosses the restart
threshold.
The following is the SNMP event monitor process of EAA:
1. Compares the variable sample with the start threshold at sampling intervals until the
comparison result meets the condition specified by the start operator.
2. Executes the policy.
3. Compares the variable sample with the restart threshold at sampling intervals until the
comparison result meets the condition specified by the restart operator.
4. Compares the variable sample with the start threshold at sampling intervals until the
comparison result meets the condition specified by the start operator.
5. Executes the policy again.
This process cycles for the monitor policy to be executed and re-executed.
