In this white paper, we examine how to use Wireshark, the world's most popular open-source network analyzer, to troubleshoot some of the top causes of poor network performance, including high latency, packet loss, inefficient window sizes, intercepting devices, and application dependencies. 

This comprehensive, 94 page guide is a how-to resource handbook for network engineers. This guide covers the fundamentals of how applications work, how applications flow, where applications fail and best practices and methodologies for troubleshooting network and application problems. 

By continuously monitoring shared capacity utilization trends in your VMware ESX environment, Capacity Analyzer significantly reduces the time and costs of identifying current capacity bottlenecks causing performance problems. 

Intel IT implemented a proactive problem management process based on analysis of objective, largely system-generated data from client PCs across our worldwide environment. 

Adrian Mitu, of IBM, discusses the importance of service availability and performance. Companies need to be more effective at solving service problems-- by minimizing service downtime and reducing the number of incidents. 

Common problems with interdepartmental handling of customer issues include a mismatch of priorities, no shared understanding of customer impact, and overall communication problems between teams. The solution is to create enterprise-wide workflow and visibility.. 

Blended threats are spam stealth attacks, moving undetected through your mail servers—blending in with all the other email—until they strike. They can compromise personal or corporate data, "recruit" computers into a network of bots, or initiate keystroke recording that collects passwords and other information. 

Troubleshooting is a necessary evil. Where does one start when the operating system does not start, the application does not load or run correctly, the network hangs or a network service does not listen or perform? Linux is noted for being rock solid, stable, and easy to manage but not as user friendly.

Learn best practices to get business value out of advanced load testing features, the limits of load testing 1.0 solutions, how today's approach complements existing 1.0 solutions, and what factors are important for selecting successful Load Testing 2.0 solutions. 

This paper discusses how and why to design SQL that will reduce the number of times calls are made to DB2. We'll look at how to write SMART applications rather than writing applications that act like generic I/O modules to DB2, properly tune SMART SQL, and how to exploit SQL and application features in DB2 on z/OS version 8 and 9.
