Keynote Systems (Nasdaq:KEYN), the worldwide leader in Web performance measurement and management services, has significantly broadened the Keynote Application Perspective(R) platform by doubling the number of worldwide geographical locations from which customers can measure transaction performance and introducing a version of Application Perspective that offers deep integration with HP OpenView. The enhanced version of Application Perspective Outside Edition, which includes additional monitoring locations, and the new Application Perspective for HP OpenView service, are immediately available to customers.

The Keynote Application Perspective platform is the industry's most comprehensive, end-to-end monitoring and root cause diagnostics solution for e-business applications at the lowest total cost of ownership. The platform consists of three modules that can be purchased and used independent of one another: Application Perspective Outside Edition, Application Private Edition (a high throughput transaction monitoring agent that can be placed anywhere a customer desires inside or outside the firewall), and Application Perspective for HP OpenView, a newly available version now tightly integrated with HP's OpenView Transaction Analyzer product, that facilitates deep diagnostics behind the firewall when application performance problems occur.

Keynote Application Perspective Outside Edition is an affordable, self-service, outside the firewall, Web transaction monitoring service that measures the 'response time' and 'success rate' for performing Web transactions from multiple geographic locations worldwide.

When Outside Edition initially became available in February, transaction monitoring was immediately available from 15 cities. Keynote has now added an additional 15 cities from which customers can measure, monitor and diagnose transaction performance from the end user perspective. The additional North American geographic locations from which customers can monitor transaction performance now include: Atlanta, Miami, Seattle, Cleveland, Minneapolis and Toronto. The additional international locations include: Brussels, Helsinki, Madrid, Milan, Oslo, Singapore, Shanghai, Sydney and Tokyo.

Application Perspective for HP OpenView is an inside the firewall, appliance-based service designed to provide high-capacity, real time transaction monitoring with sophisticated trending, alarming and reporting and that includes integration with HP OpenView Transaction Analyzer (OVTA). HP OVTA provides operations and application support staff with a comprehensive understanding of current application performance and drill-down functionality deep into the application layer for rapid problem isolation.

The benefits of Keynote Application Perspective for HP OpenView include:

-- Rapid detection of performance issues as perceived by end

users.

-- Seamless drill-down to application root cause.

-- Fast resolution of complex issues resulting in reduced mean

time to respond and repair.

-- Instant validation of fixes and performance enhancement for

end users.

Together, Application Perspective Outside Edition and Application Perspective for HP OpenView bring enterprise customers an elegant services-based platform for Application Performance Management (APM). Keynote's APM services platform delivers the industry's most comprehensive end-to-end operational monitoring and root cause diagnostics solution for e-business applications at the lowest total cost of ownership, especially when compared to complex and costly software solutions from companies such as Mercury Interactive.

Strong Customer Testimonials

"Sun Country has added more functionality to its Web site and greatly increased its presence on the Web over the last two years intensifying the need to monitor large numbers of transactions to maintain excellent customer service and address problems proactively, yet cost effectively. Keynote Application Perspective is the answer," said Mark Ondrey, Director of IT for Sun Country Airlines. "Our Web site is mission critical to our business as we drive more and more customers to it and to make it useful for our employees who need to access information on our extranet from all over the country. By broadening the geographic locations available for us to measure our site's performance from with Outside Edition, we are able to assure that our destination cities can successfully access our site quickly and reliably. Application Perspective is easy to use and the detail provided gives us the ability to triage a problem efficiently at the correct level. The Keynote service is a vital component of our proactive approach to customer and enterprise application maintenance. Sun Country is already realizing a significant return by reducing site downtime and pinpointing potential trouble spots, rather than waiting for a problem to surface."

"It is impossible to be in a more time sensitive business requiring more accuracy than providing real time stock charts," said Chip Anderson, president and CEO of StockCharts. "Our Web site gives customers access to some of the most powerful analysis tools available. Because we offer our customers direct support, running such a powerful Web site is a 24/7 job. Keynote Application Perspective is easy to install and deploy and provides us all the high frequency performance monitoring and root cause analysis functionality we need provided as a highly cost effective service. The large number of measurements, that a single Application Perspective private agent can generate, allows us to detect problems very quickly. Application Perspective can generate thousands of pages per hour so that we can monitor all our applications from a single agent and provision new transactions measurements and perform advanced troubleshooting transactions very quickly facilitating real time triage and diagnosis."

How Application Perspective for HP OpenView Works

Transactions originated from Application Perspective Outside Edition agents or Private Agents run through a company's end-to-end infrastructure just like a "red dye" diagnostic test -- with or without detailed instrumentation data. With integration completed between Application Perspective and HP's Open View Transaction Analyzer, Keynote transactions can now be identified and followed through a company's underlying Web, database and application servers and the impact of each component upon end user experience can be closely monitored. When an end user experience threshold (performance or availability) is exceeded, Application Perspective generates alerts instantly within the MyKeynote Inside Operational Console and also feeds alerts to a company's existing HP Open View console.

For data center issues, operation and application support managers can instantly drill down to page-level and metric-level details to eliminate false alarms and triage the problem. Following the problem resolution, Application Perspective for HP OpenView can also be used to validate the fix in real time, thus providing a highly efficient, repeatable process to enhance the end user experience.

Availability and Pricing

Application Perspective Outside Edition and Application Perspective for HP OpenView are immediately available.

Outside Edition pricing starts at $70 per page from 5 U.S. cities at 15-minute frequency ($350 for a five page transaction) and $100 per page from 10 U.S. cities also at 15-minute frequency ($500 for a five page transaction).

The Application Perspective for HP OpenView solution is priced at $5,000.00 per month and includes the Application Perspective High Frequency Private Agent, MyKeynote Inside Operations Console, HP OpenView Adapter and OVTA instrumentation capabilities.
