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

Log File Configuration

You can use the following methods to configure logging options.

  • Use group policy settings to configure the log location, verbosity, and retention policy. Use the View Common Configuration ADMX template file, vdm_common.admx.
  • Use a command-line command to set a verbosity level. Navigate to the C:\Program Files\VMware\VMware View\Agent\DCT directory and enter support.bat loglevels. A new command prompt window appears, and you are prompted to select a verbosity level.
  • Use the vdmadmin command with the -A option to configure logging by Horizon Agent. For instructions, see the Horizon Administration document.

Collecting a Log Bundle

You can use a command-line command to collect logs into a ZIP file that you can send to VMware Technical Support. From the command line, navigate to the C:\Program Files\VMware\VMware View\Agent\DCT directory, and enter the support.bat command.
