9:30 – 10:30 Performance Management in Virtualized Environments
Speaker: Emmanuel Sauvion, Sysload Software
Today, some type of Virtualization can be found in just about every IT shop on the planet. Server troubleshooting and performance management has changed since the emergence of Virtualization, and this presentation will review the various changes and focus on specifics and similarities of three major players in the market today: IBM AIX, SUN Solaris and VMware ESX.
10:45 – 11:45 Event Profiling in z/OS
Speaker: Dave Day, Colesoft Marketing Inc.
All of the application profiling products on the market today have a common theme - they all run on an interval, where there is a sleep component and an active component. During the active component, the application is usually ‘frozen’ while the profiling logic records information from various control blocks associated with the application. The data recorded by the profiler is referred to as ‘state’ data. The ‘state’ of the application can be deduced by examining the recorded data. Event Profiling takes a different approach. The data to be recorded starts at the processor level, not the address space. Event Profiling starts at a lower level. Processor event data is gathered for all active processors for the z/OS image. Processor event data is then scanned for those events that relate to the profiled address space/application, and only those events are recorded. The event data recorded by the operating system indicates the ‘state’ of the application for a given event. By combining events, it is possible to create a profile for an application that is orders of magnitude beyond the capability of existing ‘state’ profilers. And, it is done without any impact to the target application.

1:00 – 2:00 Business Transaction Management - The Evolution of End User Monitoring
Speaker: Scott Sumner, Optier
There is a paradigm shift in how IT organizations are monitoring their mission critical applications today. Because IT organizations are service oriented, the approach to monitoring should be from the user’s perspective and not from an infrastructure perspective. Moreover, this user experience is delivered through their actual business transactions. Over the years technologies such as synthetic transaction monitors and end user monitors (network sniffers) have provided some visibility. However, neither technology has provided a complete and comprehensive view into the performance of critical business transactions. With Business Transaction Management (BTM), IT organizations are now empowered to focus on the exact point where the Business and IT intersect. This presentation will cover how End User Monitoring is evolving into BTM to provide a comprehensive solution for monitoring your applications from a business transaction perspective.
2:15 – 3:15 Survival Analysis in Computer Performance Analysis
Speaker: Brian Barnett, Bank of America
Survival Analysis is a statistical technique that deals with biological events and mechanical failure. It uses a nonparametric approach that handles continuously distributed and discrete data, detects significance, enables predictions, evaluates time to events (response time) and allows event censoring (equipment swaps). Brian’s presentation will provide insight into how Cox Regression Analysis works and how it was implemented using SAS to identify critical components of computer performance and capacity problems. This methodology worked and improved performance in areas that were previously intractable.
