ClearSight Networks this week is making available an updated version of its ClearSight Analyzer probe technology that now includes more support for VoIP applications and IPTV.
The company, formerly AppDancer, updated its traffic analysis tool to provide comprehensive analysis of VoIP performance issues by monitoring live network traffic. ClearSight packages its software on an appliance and says its ClearSight Analyzer 6.0 (for both the stand-alone and distributed deployment models) includes improved reporting to help customers better understand what is going on with applications up to Layer 7. The company is adding support for VoIP applications including MSN and Skype as well as enhancing support for IPTV through video playback, video quality and channel zapping analysis.
"It has been really exciting for us as a company to see IPTV and video-on-demand services increasing in popularity. Such high bandwidth transactions and applications are ideal for our software's capabilities," says John Kenney, vice president of marketing at ClearSight.
The ClearSight analyzer's core component is software. As customers advance, the software is packaged on a portable hardware test tool. The company says it’s not an appliance in the standard sense, because it does not require rack mounting. ClearSight Analyzer can be deployed on any PC system with Windows 2000, using most standard network interface cards. In the future, ClearSight Analyzer will also be deployable on common network management platforms, such as Solaris.
With this release, ClearSight says it improved the drill down capabilities to help customers pinpoint problems more quickly. For example, in a distributed model, ClearSight analyzers can now display activity for an application, then pinpoint it down to a particular server, further drill into a particular flow, and then isolate the media content of that flow, the company says.

Diagnosing why an application is slow is hard, at times taking days or weeks to isolate and resolve. This paper explains the challenges involved using current management tools, provides a 'wish list' for application management and analysis, and explains the need for an application system-wide approach that monitors entire applications, not components.
This paper highlights the impact of virtualization on application performance. "Managing Application Performance in Virtual Environments" states: "Best-in-Class organizations are predominately taking actions around improving visibility across both physical and virtual systems, assessing the business impact of application performance and understanding interdependencies of applications in virtualized environments."
Forrester Research analyst Glenn O'Donnell and BlueStripe co-founder Vic Nyman discuss a breakthrough approach to application problem management. Learn the new approach for ITSM problem management, which provides: Rapid isolation of application slow-downs to specific components for quick problem resolution, 24/7 monitoring for proactive notification of potential issues before end users are impacted and much more.
