Command-Line Options

The following table describes the command-line options and usage.

Option Usage Description
-l -l Lists log levels for all the features and components that DCT supports.

For example, the output of the Horizon Client for Windows command support.bat -l lists all the components that DCT controls and the log level status:

- Agent Core          [INFO]
- PCoIP               [INFO]
- Virtual Channel     [INFO]
- VDP Service         [TRACE]
- Remote Features 
    - Client Drive Redirection  [TRACE]
    - Clipboard Redirection     [DEBUG]        
    - Drag and Drop             [TRACE]
    - DPI Synchronization       [INFO]
    - File Type Association     [INFO]
-l feature1,feature2 ... Lists log levels for the specified features.
For example, the output of the Horizon Client for Windows command support.bat -l CDR,DnD lists the log level status for the Client Drive Redirection and Drag and Drop features:
 - Client Drive Redirection  [TRACE]    
 - Drag and Drop             [TRACE]
-l -dumps Queries the dump settings for the configured processes.

For example, the output of the Horizon Client for Windows command support.bat -l -dumps lists the name, dump type, and maximum dump count for each process:

Process Name                  Dump Type   Max Dump Count
========================================================
vmware-view.exe               Full        128
vmware-remotemks.exe          Full        128
vmware-appstub.exe            Full        128
horizon_client_service.exe    Full        NO LIMIT 
Note: This command is available only for Horizon Client for Windows.
-l -dumps count Queries the dump count for the configured processes.
Note: This command is available only for Horizon Client for Windows.
-l -dumps type Queries the dump type for the configured processes.
Note: This command is available only for Horizon Client for Windows.
-ld -ld feature1,feature2 ... Lists log level details for the specified features.
-x -x All:level Sets the log level for all the features that DCT supports. Valid log levels are as follows:
  • Info
  • Debug
  • Trace
  • Verbose
-x feature1:level1,feature2:level2 ... Sets the log level for the specified features or components.

For example, the Horizon Client for Linux command vmware-view-log-collector -x All:TRACE sets the log level to Trace for all components. The Horizon Client for Linux command vmware-view-log-collect -x DnD:INFO,CDR:TRACE sets the log level for the Drag and Drop feature to Info and the log level for the Client Drive Redirection feature to Trace.

-d -d directory1 Redirects DCT output to the specified directory.
-f -f bundleName Specifies the full name of the log bundle file to bundleName.
-h -h Displays help information for command-line options and lists supported features and components for DCT.
-del -del -dumps All Deletes the dumps for all the features and components that DCT supports.
Note: This command is available only for Horizon Client for Windows.
-del -dumps feature1,feature2 ... Deletes the dumps for the specified features.

For example, the output of the Horizon Client for Windows command support.bat -del -dumps Client,FA deletes the dump files for the Client and File Type Association features.

Note: This command is available only for Horizon Client for Windows.

Real-Time Dump

For Horizon Client for Windows and Horizon Agent for Windows, real-time dump is also supported for some features. This function dumps the target process based on the configuration file setting and collects the dump in the log bundle. Whether a real-time dump needs to be generated depends on the feature's configuration.

For example, if you run the command support.bat -c for Horizon Client for Windows, the message You can choose to generate diagnostic dumps of the VMware Horizon Client processes running on this machine, please note these files can be very large appears. If you choose Y, dump files are generated for existing processes related to Horizon Client for Windows.
