When users call in complaining about their experience with virtual desktops and apps, it’s extremely hard to identify where these bottlenecks are occurring. This session will show you how to visualize the actual user experience using Citrix HDX Insight. Through live demos you will learn how to install and configure HDX Insight and Web Insight to monitor XenDesktop traffic and immediately identify the location of a bottleneck, saving hours of troubleshooting and resulting in happier customers. In this session I will cover: • Installation/configuration of HDX Insight using wizards/manual configuration • Identification of bottlenecks/performance issues affecting user experience • Integration into XenDesktop Desktop Director

5. • A user calls in and tells support that his desktop is going really slow.
• You check Desktop Director to see server health but no issues…
• You logon to the same server…everything fine…
• You ask the user to reboot the computer, go into a tunnel and hope the
new guy picks up the redial…
The Challenge!

6. • A user calls in and tells support that his desktop is going really slow.
• You check Desktop Director to see server health but no issues…
• You switch to NetScaler Insight tab and see really high network latency on
the clients network…
• You ask the user to run a speedtest and then contact his internet provider
since lets face it…100kb is not suitable for AutoCAD over HDX.
What should have happened…

7. HDX
Uses AppFlow to show:
• Real-time latency, Round-Trip-Time and session details like for XenApp and
XenDesktop.
• Historical reports for trend analysis and capacity planning.
• End-to-end performance data from the user to the virtual desktop
environment
Why NetScaler Insight

8. Web
Same benefits as HDX and…
• Top clients and URLs accessed.
• Number of overall requests
• Total bandwidth being consumed
• Back-end infrastructure response times.

A: No.
FAQ

17. Remember
• NetScaler CPU usage
• Internal traffic – StoreFront single sign-on issue
• Session reliability currently breaks, use ICA KeepAlive until fixed
Also keep in mind…
