Create a Data Collection Tool Bundle for Horizon Agent

To assist Technical Support in troubleshooting Horizon Agent, you might need to use the vdmadmin command to create a Data Collection Tool (DCT) bundle. You can also obtain the DCT bundle manually, without using vdmadmin.

For your convenience, you can use the vdmadmin command on an Horizon Connection Server instance to request a DCT bundle from a remote desktop. The bundle is returned to Horizon Connection Server.

You can alternatively log in to a specific remote desktop and run a support command that creates the DCT bundle on that desktop. If User Account Control (UAC) is turned on, you must obtain the DCT bundle in this fashion.

Procedure

  1. Log in as a user with the required privileges.

    OptionAction
    On Horizon Connection Server, using vdmadminLog in to a standard or replica instance Horizon Connection Server as a user with the Administrators role.
    On the remote desktopLog in to the remote desktop as a user with administrative privileges.
  2. Open a command prompt and run the command to generate the DCT bundle.

    OptionAction
    On Horizon Connection Server, using vdmadminTo specify the names of the output bundle file, desktop pool, and machine, use the -outfile, -d, and -m options with the vdmadmin command.
    vdmadmin -A [-b authentication_arguments] -getDCT -outfile local_file -d desktop -m machine
    On the remote desktopChange directories to c:\Program Files\View\Agent\DCT and run the following command:
    support

Results

The command writes the bundle to the specified output file.

Example: Using vdmadmin to Create a Bundle File for Horizon Agent

Create the DCT bundle for the machine machine1 in the desktop pool dtpool2 and write it to the zip file C:\myfile.zip.

vdmadmin -A -d dtpool2 -m machine1 -getDCT -outfile C:\myfile.zip

What to do next

If you have an existing support request, you can update it by attaching the DCT bundle file.
