Modern Application Performance Management (APM) solutions can be tremendously helpful in delivering end-to-end visibility into the application delivery chain: across all tiers and network sections, all the way to the end user. In previous blog posts we showed how to narrow down to various root causes of the problems that the end users might experience. Those issues ranged from infrastructure through application and network, and through the end-user client application or inefficient use of the software. When the problem comes from the end user application, e.g., a Web 2.0 Web site... (more)
