Limiting alert notifications

To prevent being overwhelmed with notifications, you set up the notification limiter to govern the number of notifications sent within a specified time period. For example, you set the notification limit to 100 notifications within 20 minutes with a 10 minute reset time, which is the default. Once 100 notifications are sent within the 20 minute time period, notifications are suspended for 10 minutes, which is the reset time.

The Notification Limiter dialog indicates if notifications are being sent or suspended and the countdown for the reset. Once the Current Count reaches the limit, the Reset Duration starts to increment. The Missed Notification indicates the number of notifications that were not sent. Click Refresh to renew the display information.Once the Reset Duration reaches the limit, all counts return to zero. You can manually reset the counter when notifications are suspended by clicking Reset.

Managing monitored domain controllers

The first time you open the Agents option, the Monitored Domain Controllers page display is empty. The first task is to install a Active Directory Health Analyzer agent. See Installing Active Directory Health Analyzer agents. Once an agent is installed the Monitored Domain Controllers page lists the domain controllers monitored by Active Directory Health Analyzer agents. The name of the server monitoring each domain controller is listed in the Monitored by column.
