Summary

In this chapter, you looked at some of the key areas that can affect WebSphere application performance and looked at what tools are available for Windows (NT/2000/XP), Linux, Solaris, and AIX.

Throughout the discussion, you saw how to read and interpret the output from these tools to understand what the data means and at what point you should be concerned . This is important for you to build up historic metrics to determine how your environment isn't only performing but also how it's matching any Service Level Agreements (SLAs) you may have with your WebSphere environment.

Further, you explored several approaches to plot the output from the server monitoring tools and WebSphere components for proactive and historic element monitoring. In Chapter 14, you'll explore the implementation of several monitoring tools that provide historic graphing capabilities.

By this stage in the book, you should be able to architect a robust and highly available topological architecture, implement scalable and high-performing server and network components, implement high-performing application code, tune and optimize WebSphere, and proactively manage your WebSphere environment.
