  6. After selecting the desired options for each tab and entering the appropriate threshold variables and values, specify your choices for the Notification and Polling sections of the dialog.

    Notification

    Select the notification policy you would like to apply to this threshold. This policy kicks off 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, while no notifications will generate for the threshold, a workspace report with the out of threshold items will still appear on the Alert Center Home page, and out of threshold items will be listed on the Items Report.

    Polling

    Enter a value for the polling interval, or the interval at which the Alert Center checks the WhatsUp Gold database to see if there are items out of the threshold's parameters. The default polling interval is 3 minutes.

    Note: We advise that your polling interval be shorter than the amount of time for which you are gathering data for this threshold. For example, if you configure a threshold that checks CPU data every 10 minutes, your polling interval should be 9 minutes or less. If the polling interval is longer than the data sample period, the Alert Center may miss data relevant to the threshold.
