End-to-end performance monitoring can be extremely useful as a proactive method for both rapid troubleshooting and performance management of enterprise networks and server farms. It has been successfully implemented to quickly identify and resolve the myriad of performance issues associated with networks, servers, and applications. The use of end-to-end performance monitoring appliances has uncovered serious inefficiencies with load balancers, poorly designed applications, bypassed proxy servers, ineffective cache servers, aggressive active agents, and badly designed “redundant” networks. They can provide the “big-picture” view of networks and applications, answering questions that are critical for the end-user experience: “What impact will server consolidation have on my users?” “Which will work better on my network, thick or thin clients?” “Which of my sites are in greatest need of upgrades (or downgrades)?” and “Which web pages are the slowest to download?”

This method for solving application response time problems offers drill-down troubleshooting capabilities to reveal metrics that can save you weeks or months of time in identifying and resolving issues. Analyses that previously required weeks to complete with packet sniffing tools can be accomplished in minutes when end-to-end performance monitoring appliances are properly configured. Because they continuously monitor applications, such appliances notice and report even difficult intermittent issues that cannot readily be reproduced. If a problem occurred at 3 a.m. the previous morning, their stored reports can be used for a post-mortem analysis. There is no need to wait for a recurrence in order to capture the behavior the way legacy troubleshooting tools require. End-to-end performance monitoring appliances with intelligent thresholds can alert your various teams to a developing problem before customers are severely impacted. Their proactive management and high-level views allow you to discover new ways to optimize the network—they can “find new money” at a time when you need it most. Not all end-to-end performance monitoring offerings are created equal. Some are focused on a specific task or application that limits their broader value.
