HDX Insight


HDX Insight is part of the NetScaler Insight Center 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 NetScaler or Citrix SD-WAN application networking fabric.

In this release, the Linux VDA partially supports the HDX Insight feature. Because the End User Experience Management (EUEM) feature is not implemented, the data points related to time duration are not available.


No dependent packages need installation.


HDX Insight analyzes the ICA messages passed through NetScaler between Citrix Workspace app and the Linux VDA.

You must set up an Insight Center environment with the Linux VDA and enable the HDX Insight feature. For the information on using the HDX Insight feature, see Use Cases: HDX Insight.


No data points are displayed

There might be two causes:

  • HDX Insight is not configured correctly.

    For example, AppFlow is not enabled on NetScaler or an incorrect instance of NetScaler is configured on the Insight Center.

  • The ICA Control Virtual Channel is not started on the Linux VDA.

    ps aux | grep -i ctxctl

    If ctxctl is 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.

Known issue

Unable to display the data points related to time duration. Because the EUEM feature is not implemented, the data points related to time duration (such as ICA RTT) are unavailable and are displayed as N/A.
