Analyzing health of a selected domain controller

Analyzing health of a selected domain controller

You can view information on all monitored domain controllers or a selected monitored domain controller. To view information on all domain controllers, see Analyzing health of all domain controllers.

To analyze health on a selected domain controller

1	Select Active Directory Health | Analyzer.

2	Expand the tree, and expand Monitored domain controllers.

3	Select a domain controller.

4	Use the tool bar, page heading, and the tabs to view and manage domain controller health. See Using the analyzer pages.

 

The page heading displays general information about the selected site.

Table 35. Domain controller general information

Field	Description
Domain	Name of the domain in which the domain controller resides
Site	Name of the site in which the domain controller resides
Forest	Name of the forest in which the domain resides
OS version	Version of the operating system
System up time	Duration of time the domain controller has been running
Read only DC	Indicates if the domain controller is a read-only domain controller (RODC)
Global catalog	Indicates if the domain controller is a global catalog server
Monitored by	Name of the domain controller on which the agent is installed that is monitoring the selected domain controller
Last updated	Date and time the domain controller was last updated

The bottom pane changes depending on the tab you select. The following table lists the tabs and the information displayed.

NOTE: A message displays if there is no data to display. There may be a pending workload evaluation or the system is waiting on data from the Active Directory Health Analyzer agent. Check to see if the Active Directory Health Analyzer agent is running. If there is no data because the domain controller is not being monitored, you need to install the agent. See Installing Active Directory Health Analyzer agents. Data collectors provide the input to the various tabs. Some data collectors can be enabled or disabled. See Managing data collectors. If you do not see the corresponding data, make sure the data collector is enabled and the necessary permissions are set. To check the required minimum permissions, see the dialog box for the individual data collector or the Alerts Appendix. The remaining data collectors used to provide information to the tabs are not available for management and are provided to Active Administrator® through Windows® Management Instrumentation (WMI).
