Citrix upgrades app to focus on end-user experience

Citrix Systems this week announced it had upgraded its application performance management software to help companies better gauge the user experience.

Citrix, which acquired Reflectent Software in May, says its EdgeSight application monitoring product line can track and report on performance in real time from a user perspective across application types. The new releases are available as Citrix EdgeSight 4.2 for Endpoints, which monitors the performance of any application, and Citrix EdgeSight 4.2 for Presentation Server, which provides additional visibility into applications delivered by Citrix Presentation Server, the company says.

EdgeSight 4.2 for Endpoints comprises client agents that collect performance, availability and other application information as well as server software that aggregates data from the agents. The agents can send real-time alerts to the server software, as well as forward data used for tracking trends. The agents work on desktop, laptops or mobile devices, and can store data for up to 30 days. Network managers access the data via a Web-based interface.

EdgeSight 4.2 for Presentation Server works specifically with Citrix's product. The two companies had partnered in 2005 to report on the client experience with applications delivered via Citrix's Presentation Server, software that promises to control, secure and manage user access to applications and data running on centralized Citrix servers.

This release will provide system administrators with "visibility into session-level performance" and diagnostic capabilities that will help them isolate and resolve performance problems in real time, the company says. The software also provides capacity-planning features by analyzing resource consumption, Citrix says.

Client-side application management is a critical step in monitoring performance, industry watchers say, especially as more applications are disassociated from specific servers and delivered via Citrix servers, Web services or as components of a service-oriented architecture.

"Today, applications are more complex and no longer tightly coupled to the underlying infrastructure," George Hamilton, director of enterprise computing and networking at the Yankee Group, wrote in a report. "The correlation of infrastructure performance to end-user experience has broken down, driving the need for better management of applications within a production environment and active management of the end-user experience."

Citrix EdgeSight 4.2 is priced based on the solution purchased and the size of the deployment. The company says pricing starts at approximately US$70 per user.
