Log File Configuration

You can use group policy settings to make the following 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 Configure PCoIP event log verbosity.
  • For client user interface 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)\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 the client user interface, or a command-line command, to collect logs into a ZIP file that you can send to Omnissa Technical Support.

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