End-to-End Performance Monitoring to the Mth Tier (Mainframe Integrated) using End User Experience

An “end-to-end performance monitoring” view of an enterprise, is based on the “End User Perspective”, as proposed by the Apdex Alliance*. This includes the “application” perspective, and it means that “Performance Is The User Experience”.

Since the 80/20 Rules Have Flipped, there is a new approach to overall performance monitoring. The old rule said that 80% of your users are in your primary offices and that 80% of you traffic is inside your network. Therefore, if you deliver good service to the 80% you know, then you are well ahead of the game. 

The new rule says that 80% of the users are outside your primary offices and that 73% of application service problems are reported by end users, not by the IT department.

This session will show the flow of data, where it gets impacted (cloud, distributed and Mainframe) and how to monitor performance from the “End User Experience” – thus avoiding silo monitoring with a “war room” type analysis.
