Analyzing Active Directory health

The Active Directory Health Analyzer displays read-only real-time data about forests, sites, domains and domain controllers so you can monitor the health of your organization. The data on the screen you are viewing is refreshed automatically every minute by default. You also can refresh the data manually by clicking Refresh.

NOTE: The Active Directory Health Analyzer agent sends data every five minutes to the Active Administrator® database. When a data collector falls out of range, data is sent every 30 seconds to the database. You can adjust the automatic refresh rate from 30 to 3600 seconds or turn off the automatic refresh. If you turn off the automatic refresh, you can refresh the screens manually. See Setting Active Directory Health Analyzer options.

Topics:

Managing the Active Directory Health Analyzer tree

The Active Directory Health Analyzer tree displays forests, domains, sites, and domain controllers. By default, unmonitored domain controllers display beneath a selected domain. If you want to see only monitored domain controllers beneath a selected domain, clear the Display unmonitored domain controllers in the tree view check box in Settings | User Options. See Setting Active Directory Health Analyzer options.

To filter the tree, type in the Filter objects box. The list filters as you type.
