The Linux VDA partially supports the HDX Insight feature. HDX Insight is part of the Citrix Application Delivery Management (ADM) and is based on the popular industry standard AppFlow. It enables IT to deliver an exceptional user experience by providing unprecedented end-to-end visibility into the Citrix ICA traffic that passes through the Citrix ADC or Citrix SD-WAN application networking fabric. For more information, see HDX Insight
No dependent packages need installation.
HDX Insight analyzes the ICA messages passed through the Citrix ADC between Citrix Workspace app and the Linux VDA. All HDX Insight data is sourced from the NSAP virtual channel and sent uncompressed. The NSAP virtual channel is enabled by default.
The following commands disable and enable the NSAP virtual channel, respectively:
sudo /opt/Citrix/VDA/bin/ctxreg create -k "HKLM\Software\Citrix\VirtualDesktopAgent" -t "REG_DWORD" -v "EnableNSAP" -d "0x00000000" --force
sudo /opt/Citrix/VDA/bin/ctxreg create -k "HKLM\Software\Citrix\VirtualDesktopAgent" -t "REG_DWORD" -v "EnableNSAP" -d "0x00000001" --force
No data points are displayed
There might be two causes:
HDX Insight is not configured correctly.
For example, AppFlow is not enabled on the Citrix ADC or an incorrect Citrix ADC instance is configured on the Citrix ADM.
The ICA Control Virtual Channel is not started on the Linux VDA.
ps aux | grep -i ctxctl
ctxctlis not running, contact your administrator to report a bug to Citrix.
No application data points are displayed
Verify that the seamless virtual channel is enabled and a seamless application is launched for a while.
