Step-by-Step: Configuring the VMware UEM Debug Level

Tom Fenton walks you through the process of configuring the Debug level in VMware User Environment Manager.

VMware User Environment Manager (UEM) is an interesting product that allows you to have a central management portal that can control an end user's desktop Group Policies and settings. While I was recently working on some issues that I was having with UEM, which required me to troubleshoot, I couldn't find any step-by-step guide on how to increase the Debug level for UEM. I was, however, able to figure out how to do this after spending some time sifting through various documents and poking around various sources. Let me help make your life a little easier by showing you how.

Setting the Debug Level During Initial Install
When the UEM manager is installed, you need to use the Group Policy Management interface on your Active Directory server to set various UEM parameters, include logging. While doing this, you have the option to enable debugging, set the Debug level and specify the location of the log files. However, once the parameters are initially configured, the UEM manager interface doesn't have a specific place where you can change the Debug level.

Changing the Debug Level
Before changing the Debug level, let's look at the UEM logs and review the level of detail captured in the log (Figure 1). Note, the log snapshot in Figure 1 is pretty empty as I'm only setting the log level to capture WARN errors.

To change the log level, I needed to return to my AD server and bring back up the Group Policy Management interface. From the Group Policy Management Editor, I navigated to Domains | <domain name> | UEM, then right-clicked UEMPolicies and selected Edit (Figure 2).

In the left pane of the Group Policy Management Editor, I navigated to User Configuration | Policies | Administrative Templates | VMware UEM | FlexEngine. In the right pane, I double-clicked FlexEngine logging (Figure 3).

In the FlexEngine logging window, you can select the log level from the dropdown menu and specify the location of the log files (Figure 4).

After changing the UEM logging level to Debug and performing some UEM activities, I examined the UEM logs again and saw that Debug level logging was being captured (Figure 5).

Change the Debug Level for a Single User
If you only need to change the Debug level for a single user, you can create a FlexDebug.txt file in the same folder as the standard log file for the UEM user. This will trigger FlexEngine to switch to Debug logging only for that user.

Wrapping Up
Once I figured out how to change the log levels in UEM, the process was straightforward and made sense because it was the same place that I originally configured them. Hopefully you won't need to change your Debug level, but if you do, it's good to know that there is an easy way.
