Known WMI issues in Windows Server 2008

Microsoft® has identified a number of known issues with WMI services in Windows® Server 2008. The following issues may occur:

•
The database agent OS validation or collection has errors, even when the OS credentials are correct.
•
The WMI reports incorrect data from the performance classes.
•
Remotely accessing WMI causes memory leaks in Windows Server 2008.
•
The WMI reports are unstable.
•
In SQL Server 2008, the perfmon counters do not appear under WMI because they do not exist.
To resolve these issues:
1
Using the same OS credentials as the agent uses, run perfmon /wmi on the monitored host.
2
Install the hotfixes available in the following Microsoft support articles on the Windows 2008 machine:
•

Tuning WMI connections

The following parameters can be used to fine tune the Windows Management Instrumentation (WMI) connections made by Foglight® agents. You can set these parameters for Foglight Agent Manager either in the baseline.jvmargs.config file as vmparameter options, or specify them directly as jvm options when starting up Foglight Agent Manager via command line. The values used for these parameters vary from environment to environment and so should be used as reference only.

•
Max Active Connections: Defines the number of simultaneous outbound connections that can be made by all agents running on a particular instance of Foglight Agent Manager. The default value is 100.
Sample: -Dcom.quest.connection.regulator.maxActiveConnectionsCap=500
•
Expire connection based on no. of executions: Defines the number of executions that can be made by a connection before forcibly closing it. The default value is 50.
Sample: -Dquest.debug.poolable.wmi.time.to.live.executions=200
•
Timeout by elapsed time: Defines the time (in milliseconds) after which a connection is expired. The default value is 600000 (10 mins).
Sample: -Dquest.debug.poolable.wmi.time.to.live.timeout.millis=900000

Modifying registry key ownership on Windows Server 2008 R2

Configuring the agent to connect to the remote Windows® Management Instrumentation (WMI) and WinShell components on Windows Server 2008 R2 systems requires certain modifications to the registry keys. In some situations, these registry keys may be owned by TrustedInstaller instead of the Administrators group, which prevents modifications from being made even by Administrator accounts.

 
* 
TIP: It is recommended that you create a backup copy of the Windows Registry that you can revert to prior to making any changes.
To modify the registry key ownership:
1
Using the registry editor, locate the registry key that you need to modify.
2
Right-click the registry key and click Permissions.
3
On the Permissions dialog box, click Advanced.
4
On the Advanced Security Settings dialog box, open the Owner tab.
5
In the Change owner to list, select the Administrators group.
 
* 
IMPORTANT: An error indicating insufficient permissions may appear. To resolve, a user with the administrative account intended to use for profiling can change the ownership of the keys to that administrative account, and then set the permissions to Full on the appropriate registry keys.
6
Click OK.
Ownership of the registry key is assigned to the Administrators group, allowing any member of that group to modify the key’s permissions. For more information about required registry changes, see Configuring registry settings for Windows Server 2008 R2 and Windows 7.

Configuring registry settings for Windows Server 2008 R2 and Windows 7

In order to allow the agent to connect to the remote Windows® Management Instrumentation (WMI) components on Windows Server 2008 R2 or Windows 7 systems, special registry settings are required.

To configure Windows Server 2008 R2 registry settings:
1
If necessary, add the required domain\user to the Administrators group.
a
On the desktop, right-click My Computer and navigate to Groups (My Computer > Manage > Configuration > Groups).
b
Double-click the Administrators group.
c
Add the required domain\user to the Administrators group.
d
Click Apply, and then click OK to close the dialog box.
2
Edit the Wbem Scripting Locator registry key.
 
* 
IMPORTANT: There may be multiple instances of each key, especially for 64-bit versions of Windows Server 2008 R2 and Windows 7. Each instance must be updated.
a
Run regedit.
b
Search for all instances of the keys named:
{72C24DD5-D70A-438B-8A42-98424B88AFB8} (Windows Script Host Shell Object)
{76A64158-CB41-11d1-8B02-00600806D9B6} (WBEM Scripting Locator)
{0D43FE01-F093-11CF-8940-00A0C9054228} (Windows Script FileSystem Object)
There may be multiple instances of each key, especially for 64-bit versions of Windows Server 2008 R2 and Windows 7. Each instance must be updated.
c
For each key, right-click the key and navigate to the owner permissions (Permissions > Advanced > Owner).
d
Click Other Users and Groups, and add the Local Administrators group.
e
Select the Replace Owner on subcontainers and objects check box.
f
Click Apply, and then click OK.
The security screen appears.
g
Select the Local Administrators group and grant full permissions.
 
* 
NOTE: An error indicating insufficient permissions may appear. To resolve, a user with the administrative account intended to use for profiling can change the ownership of the keys to that administrative account, and then set the permissions to Full on the appropriate registry keys.
3
Close regedit.

If configuring the registry does not solve the connection issue, you may need to disable Windows User Account Control (UAC).

To disable Windows UAC:
