USB-Specific Log Files

Omnissa Horizon Client sends USB information to log files.

To specify the USBD log level, add the following parameter in one of the configuration files.

view-usbd.logLevel = "value" 

Use one of the following values for value.

  • trace
  • info
  • debug
  • error

The configuration files are in the following locations and processed in the order listed:

  1. /usr/lib/omnissa/config
  2. /etc/omnissa/config
  3. ~/.omnissa/config

For troubleshooting purposes, you can increase the amount of information sent to USB-specific logs by using the following commands:

  1. Stop the USB arbitrator daemon.

    # sudo /etc/init.d/horizon-USBArbitrator stop
    
  2. Restart the USB arbitrator daemon using the verbose option.

    # sudo /usr/lib/omnissa/horizon/usb/horizon-USBArbitrator --verbose
    

The default USB arbitrator log file is located in /var/log/omnissa/omnissa-eucusbarb-<pid>.log, where is the process id for the USB arbitrator daemon.

To get a list of usage information, use the following command:

# sudo /usr/lib/omnissa/horizon/usb/horizon-USBArbitrator -h
