Configuring a trigger
You can specify a Boolean test, an existence test, or a threshold test for a trigger. For more information, see "Configuring a Boolean trigger test," "Configuring an existence trigger test," and "Configuring a threshold trigger test."
To configure a trigger:
Step | Command | Remarks |
|---|---|---|
1. Enter system view. | system-view | N/A |
2. Create a trigger and enter its view, or enter the view of an existing trigger. | snmp mib event trigger owner trigger-owner name trigger-name | By default, no triggers exist. The owner must be an SNMPv3 user. |
3. (Optional.) Configure a description for the trigger. | description text | By default, a trigger does not have a description. |
4. Set the sampling interval. | frequency interval | By default, the sampling interval is 600 seconds. Make sure the sampling interval is greater than or equal to the Event MIB minimum sampling interval. |
5. Specify the sampling method. | sample { absolute | delta } | The default sampling method is absolute. |
6. Specify the object to be sampled by its OID. | oid object-identifier | By default, the OID is 0.0. No object is specified for a trigger. The mteTriggerEnabled and mteTriggerTargetTag objects are read-only and cannot be sampled. |
7. Enable wildcard search for OIDs. | wildcard oid | By default, the object to be monitored is fully specified. This command must be used in conjunction with the oid object-identifier command. |
8. (Optional.) Configure a context for the monitored object. | context context-name | By default, no context is configured for a monitored object. |
9. (Optional.) Enable wildcard search for contexts. | wildcard context | By default, the context for a monitored object is fully specified. This command must be used in conjunction with the context context-name command. |
10. (Optional.) Specify the object list to be added to the notification triggered by the event. | object list owner group-owner name group-name | By default, no object list is specified for a trigger. |
11. Specify a test type for the trigger. | test { boolean | existence | threshold } | By default, no test type is specified for a trigger. |
12. Enable the trigger. | trigger enable | By default, a trigger is disabled. |
