Overview

This information includes understanding the application flow that satisfies the end user request. This perspective provides...

This perspective is important for the in-depth internal understanding of who is using specific resources. Typically at this stage, you deploy some type of trace through the application, or thread analysis under load condition techniques to isolate areas of the application and particular interactions with the back-end systems that are especially slow under load. In this case, WAS provides request metrics to help trace each individual transaction as it flows through the appserver, recording the response time at different stages of the transaction flow (for example, request metrics records the response times for the Web server, the Web container, the Enterprise JavaBeans container, and the back-end database). In addition, several IBM development and monitoring tools that are based on the request metrics technology (for example, Tivoli Monitoring for Transaction Performance) are available to help view the transaction flow.
