A typical application environment consists of the different components that interact in a variety of ways to fulfill requests from the application's users: Web applications served from an application server. Databases or other data stores. Remote services such as message queues and caches. Our app agents automatically discover the most common application frameworks and services. Using built-in application detection and configuration settings, agents collect application data and metrics to build flow maps. A flow map visually represents the components of our application to help we understand how data flows among the application components. For example, the business transaction flow map for a simple e-commerce application below shows data flowing between web services, message queues, and databases.
