Log files can help troubleshoot issues with installation, display protocol, and various feature components. You can use group policy settings to configure the location, verbosity, and retention period of some log files.

Log Configuration

You can use group policy settings to make some configuration changes:

  • For PCoIP client logs, you can configure the log level, from 0 to 3 (most verbose). Use the View PCoIP Client Session Variables ADMX template file pcoip.admx. The setting is called Configure PCoIP event log verbosity.
  • For client UI logs, configure the log location, verbosity, and retention policy. Use the View Common Configuration ADMX template file vdm_common.admx.
  • For USB redirection logs, configure the log location, verbosity, and retention policy. Use the View Common Configuration ADMX template file vdm_common.admx.
  • For WSNM service logs, configure the log location, verbosity, and retention policy. Use the View Common Configuration ADMX template file vdm_common.admx.

You can also use a command-line command to set a verbosity level. Navigate to the C:\Program Files (x86)\VMware\VMware Horizon View Client\DCT directory and enter the following command: 

support.bat loglevels

A new command prompt window appears, and you are prompted to select a verbosity level.

Collecting a Log Bundle

You can use either the client UI or a command-line command to collect logs into a .zip file that you can send to VMware Technical Support.

  • In the Horizon Client window, from the Options menu, select Support Information, and in the dialog box that appears, click Collect Support Data.
  • From the command line, navigate to the C:\Program Files (x86)\VMware\VMware Horizon View Client\DCT directory and enter the following command: support.bat.
