You can use the support tool to set logging levels and generate log files for Horizon Connection Server.

The support tool collects logging data for Connection Server. This information helps VMware Technical Support diagnose any issues that arise with Connection Server. The support tool is not intended to collect diagnostic information for Horizon Client or Horizon Agent. You must instead use the support script. See Collect Diagnostic Information for Horizon Agent, Horizon Client, or Horizon Connection Server from the Console.
