- . Select this option to have the threshold alert when the database size exceeds the value you specify. The default threshold value is 80%.
: If you have an unlimited-size database, WhatsUp Gold uses a 4GB cap to calculate the size of your database.
- . Select this option to have the threshold alert when the total number of performance monitors exceeds the number you specify. The default number of total performance monitors is 3,000.
- . Select this option to have the threshold alert when the total number of performance monitor records exceeds the number you specify. The default number of total performance monitor records is 2,000,000.

- . Select this option to have the threshold alert when the total number of expired records exceeds the number you specify. The default number of total expired records is 500,000.
- . Select this option to have the threshold alert when the total number of devices being monitored exceeds the percentage of the license limit you specify. The default percentage of the license limit is 90%.

- Click the tab. Enter the appropriate threshold information:
- . Select this option to have the threshold alert when the WhatsUp service has been down for the number of minutes you specify. The default threshold value is 5 minutes.
- . Select this option to have the threshold alert when the WhatsUp discovery service is down the number of minutes that you specify. The default number is 5 minutes.
: Web service threshold checks do not apply to users running IIS.
: If you are experiencing a high volume of errors from your WhatsUp Health threshold service checks, please see Troubleshooting the WhatsUp Health Threshold.
- Click the tab. Enter the appropriate threshold information pertaining to the WhatsUp Gold Flow Monitor.
- . Select this option to have the threshold alert when the Netflow database exceeds the value you specify. The default threshold value is 80%.
: If you have an unlimited-size database, WhatsUp Gold uses a 4GB cap to calculate the size of your database.
- . Select this option to have the threshold alert when the NfArchive database size exceeds the value you specify. The default threshold value is 80%.
: If you have an unlimited-size database, WhatsUp Gold uses a 4GB cap to calculate the size of your database.
- . Select this option to have the threshold alert when the Flow collector service is down for the number of minutes you specify. The default threshold value is 5 minutes.
- . Select this option to have the threshold alert when bounce traffic occurs on a Flow Monitor source.
- . Select this option to have the threshold alert when the number of host records exceeds the amount you specify. The default threshold value is 2,000,000 records.
- . Select this option to have the threshold alert when the number of raw data records exceeds the amount you specify. The default threshold value is 10,000,000 records.
- . Select this option to have the threshold alert when the total sources sending data exceeds the percentage of license limit that you specify. The default threshold value is 90% of license limit.

- 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.
- . Select the notification policy to apply to this threshold. This policy begins sending notifications when an item is outside the configured threshold limits. If you do not see an appropriate threshold policy, or if the list is empty, click browse (...) to open the Notification Policy dialog and configure a new policy.
: Notification policies are optional for most thresholds. If you do not select a notification policy, no notifications are generated for the threshold, but a dashboard report listing the out of threshold items still appears on the Alerts Home page.
- . 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 5 minutes.
Select to have Alert Center automatically resolve items when they go back inside the parameters of the threshold.
: Configure the threshold check interval for a longer time than the sampling interval for thresholds relating to trends, such as percent utilization. Configure it for a time the same as (or similar to) the sampling interval when configuring a threshold for a health check.
Avoid setting the threshold check interval to a very short time as this can degrade system performance. In general, setting the threshold check interval to less than five minutes is inadvisable.
