Configuring an SNMP trap threshold

To configure an SNMP trap threshold:

1. Go to the Alert Center Home page:
   • From the web interface, click GO. The GO menu appears.
   • If the WhatsUp section is not visible, click WhatsUp. The WhatsUp section of the GO menu appears.
   • Select Alert Center. The Alert Center Home page appears.
   • Click Manage Thresholds. The Alert Center Threshold Library appears.
2. Click New. The Select Threshold Type dialog appears.
3. Select SNMP Trap, then click OK. The New/Edit SNMP Trap Threshold dialog appears.

   

4. Specify or select the appropriate information in the dialog fields:

   Specify a Name for the threshold; this name is displayed as the threshold's workspace report title on the Alert Center Home page.

   • Select the SNMP Trap type for which you would like the threshold to pertain. This list is populated with SNMP traps currently configured in the Passive Monitor Library.

   Threshold

   Select and enter the desired threshold criteria variables and values. The default threshold is configured to alert when the number of traps exceeds 500 in the past 60 minutes.

   Devices to Monitor

   Click Select to choose the devices to which the threshold applies. By default, the threshold monitors all devices on which the applicable monitor is enabled.

   Notification

   Select the notification policy you would like to apply to this threshold. This policy begins sending notifications when an item falls out of the threshold you configure above. If you do not see an appropriate threshold policy, or if the list is empty, browse (...) to the Notification Policy dialog to configure a new policy.

   Note: It is not required that you select a notification policy for use with every threshold. If you do not select a notification policy, no notifications are generated for the threshold, but a workspace report with the out of threshold items will still appear on the Alert Center Home page.

   Threshold check

   Enter a value for the threshold check interval, or the interval at which the Alert Center checks the WhatsUp Gold database to see if there are items that are out of the threshold's parameters.

   Select Automatically resolve items no longer out of threshold to have Alert Center automatically resolve items when they go back inside the parameters of the threshold.

   Note: We advise that your threshold check interval be longer than the amount of time for which you are gathering data for this threshold. For example, if you have devices which are set to collect CPU performance data every 10 minutes, then your Alert Center CPU threshold check interval should be set to 10 minutes or more. If the threshold check interval is shorter than the data sample period, the Alert Center may miss data relevant to the threshold.

5. Click OK to save changes.
