How to Configure Custom Alarm Criteria
The Console Alarms Manager lets you configure network alarms that provide status information for problems on your network. Alarms are triggered when certain trap or event conditions occur on your network. Alarms Manager lets you define very specific criteria to trigger an alarm using the Edit Custom Alarm Criteria window.
To define custom alarm criteria:
- In the Alarms Manager window, select By Custom Criteria (in the Criteria subtab) and click Edit Criteria to open the Edit Custom Alarm Criteria window.
- In the window, each option lets you select one or more attributes to match against in the trap or event, in order to trigger the alarm. For each option, if you check the Match On box, then Alarms Manager filters based on that category. If you don't check the Match On box, then Alarms Manager doesn't filter based on that category, and as a result, matches everything for that category. However, if you don't check any Match On boxes, then Alarms Manager won't match any trap or event.
Check the Match On checkboxes that you want to define for this alarm and select attributes within each category to be matched.- Match on Severity
