More End User Experience Monitoring
Measuring the transit of traffic from user request to data and back again is part of capturing the end-user-experience (EUE).[18] The outcome of this measuring is referred to as Real-time Application monitoring (aka Top Down monitoring), which has two components, passive and active. Passive monitoring is usually an agentless appliance implemented using network port mirroring. A key feature to consider is the ability to support multi-component analytics (e.g., database, client/browser). Active monitoring, on the other hand, consists of synthetic probes and web robots predefined to report system availability and business transactions. Active monitoring is a good complement to passive monitoring; together, these two components help provide visibility into application health during off peak hours when transaction volume is low.
This slide outlines three areas of focus for each dimension and describes their potential benefits.
User experience management (UEM) is a subcategory that emerged from the EUE dimension to monitor the behavioral context of the user. UEM, as practiced today, goes beyond availability to capture latencies and inconsistencies as human beings interact with applications and other services.[19] UEM is usually agent-based and may include JavaScript injection to monitor at the end user device. UEM is considered another facet of Real-time Application monitoring.
