Summary:

This IBM Redbooks publication offers an overview of WebSphere Studio Application Monitor for z/OS and OS/390 and WebSphere Studio Workload Simulator for z/OS and OS/390 for performance analysts, application developers and testers, and technical management. Part 1 consists of an overview of both Application Monitor and Workload Simulator. This will provide you with a good understanding of what these tools can do, who might use them, and what value they can bring to your environment. Part 2 goes into more detail on installation, configuration, and administration of Workload Simulator. Here we go into more specifics on the requirements for planning, installing, and using Workload Simulator. Part 3 goes into more detail on installation and usage of Application Monitor. Similar to Part 2, we provide more specific guidance on planning for, installing, and using Application Monitor, including several sample usage scenarios designed to illustrate the features we think you will find most useful in monitoring and tuning your own J2EE applications.
