Let there be light! With HDX Insight visibility in XenDesktop and XenApp to win
HDX Insight is an invaluable tool that organizations NetScaler provides XenDesktop to deliver hosted virtual desktops and applications with unprecedented insight into the ICA traffic on their networks. Part of the NetScaler Insight Center and additional Web Insight, HDX Insight collects, correlates and displays very informative network usage and performance data for XenDesktop / XenApp, both in its entirety. And down to the level of individual user sessions Using these data, both network and application administrators can be seen immediately and problems Triage network and application.
The beauty of HDX Insight
The main features and functions that deliver HDX Insight create unrivaled value, include the following
- Simple, inexpensive providing . Unlike other solutions that have multiple touch points and require a complex configuration of network taps or pushy agent software, HDX Insight offers end-to-end visibility with little more than one organization, the existing base of NetScaler ADCs, NetScaler gateways and Cloudbridge WAN optimizer. The necessary instrumentation (AppFlow) is already a part of this solutions; it just needs to be turned on, and pointed to an instance of NetScaler Insight Center Virtual Machine (VM). In addition, the NetScaler Insight Center VM a self-contained solution containing all necessary subcomponents, with an integral database

- output = actionable intelligence . Instead of a pile of reports raw performance data, with HDX Insight IT teams get granular and actionable information based on the automated correlation of network and application-level data. Everything needed to the source must be determined for performance issues, provided at a central location available, thereby avoiding the need to manually assemble a picture by flipping between multiple consoles.
- Granular ICA Details . Unlike solutions that identify only the presence of ICA traffic, HDX Insight not only decrypted but also analyzes ICA sessions. The result is a unique level of insight to the level of individual virtual channels.
- combination of real-time and historical data . HDX Insight eliminates the need to rely more solutions by companies addressing needs for both real-time and historical data in a single package.
- Seamless integration with Director 7.0+ . , All HDX Insight data and reports can be viewed within the same console organizations use to manage their XenDesktop environments
What HDX Insight really stands out from conventional solutions, however: (a) the width and the depth of information it provides, and (b) what the iT team can do with this information.
width and depth of the information available
High-level aggregated information with drill down to session -level data can be retrieved from different perspectives, including :.
- user Administrators can see a snapshot of the average round trip time (RTT or screen delay time), WAN latency datacenter latency and bandwidth usage for all users over periods select (eg recent 5 minutes to an hour, day, week or month). The same screen can also see top users are used by a number of attributes (eg number of applications / desktops started consumes bandwidth, latency and number of active desktops / apps), or search for individual users.
- applications. is addition to the aggregate bandwidth consumed by all hosted applications, this view provides an app-by-app breakdown that started the number of active sessions and applications, the total number of sessions and applications and start life over selection period includes periods.
- Desktops . is addition to the total bandwidth of all hosted desktops consumed, gives administrators a breakdown by user, which includes the number of active sessions and desktops, session duration, bandwidth utilization, RTT, datacenter latency and WAN latency.
- gateway . The unit / Summary data for this view is the traffic based each instance of NetScaler / NetScaler Gateway (or Cloudbridge) and provides an opportunity to compare the transit service through websites / sites.
As discussed above HDX Insight, is also the only solution that reliably dissected the ICA protocol to provide granular details of what goes in each virtual channel level right.
Figure 2: High-level overview for Desktop Information
of course is the true measure of the HDX Insight is what to do enables iT teams. So let us at a handful of common use cases a glance
#. 1a: Tactical Troubleshooting - Rajiv's reports Slowly app (s) / Desktop
The scenario in this case is a single user, Rajiv, has reported a performance problem. The entry point for the analysis is the summary screen for user information.
In addition to the aggregate user information, here we can also use the summary level to find information for individual users, including Rajiv. What we immediately notice a relatively high RTT (screen delay time) 819ms. We can also see that the WAN (12ms) and data center (1ms) latencies are low, which is the cause of the problem elsewhere. hover In fact, by Rajiv for the record drilling and for the active sessions for Rajiv on the RTT, we can see that the host is a whopping delay 587ms. So the problem is clearly in this case, the server is the IP address for which we easily seen in the recording session, as well.
# 1b: Tactical Troubleshooting - Market Reports slowly app (s) / Desktop
In this second example, we have a similar situation, this time with "market" reporting a slow experience. However, we see at once from the summary screen for the user information in this case that the client network is the main culprit.
drilling into the summary level record for market also shows high WAN latency for all market 's sessions. As a result of the support desk should "market" Options coach a powerful network service / port for the search.
If necessary, the Network Administrator / Support Desk can also take a look at the individual applications access market during its current session.
# 2 Proactive Performance Management
studies similar to those described above can also be carried out proactively to hold questions of development of major problems are. For example, an administrator who could be a group of users with high RTT all delays arise with the same host in advance to fix and noted to resolve calls from the affected user after receiving the host-level problem.
could in a similar manner, routine checking of information HDX Insight provided show a trend that proactive attention requires - as adjusting network QoS settings in response to ever-increasing amounts of video traffic
# 3 capacity / Strategic planning
HDX Insight can also be used for capacity planning of network and application infrastructure. For example, data relating to simultaneous applications, desktops and meetings in connection with the bandwidth consumption can plan / size upgrades for LAN / networks WAN are used, application licenses, NetScaler [Gateway] licenses, as well as the network infrastructure of the company in general.
The Bottom Line
Citrix HDX Insight is a powerful yet cost-effective solution for obtaining the unparalleled application and network level insight into XenDesktop and XenApp traffic on your network. With HDX Insight can proactively monitor performance problems in real-time triage and develop manage situations before they plan to bigger problems balloon, and accurately for future server and network infrastructure required IT teams.
