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: |
| -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: | |
| -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: | |
| -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:
|
| -x feature1:level1,feature2:level2 ... | Sets the log level for the specified features or components.
For example, the Horizon Client for Linux command view-log-collector -x All:TRACE sets the log level to Trace for all components. The Horizon Client for Linux command 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. | |
| -r | -r | Resets the log levels of all features to the installation defaults. |

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 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.
