New Release: The Gorilla Guide To…® Packet Capture and Analysis in Hybrid Environments, Express Edition!
Modern software systems that combine complex applications with sophisticated networks make it increasingly hard to trace a problem. Is a slowdown caused by the application, by the way it’s loaded into a browser, or by the architecture of the network? Effective tracing tools must look at many levels, and connect individual packets with the applications and hosts that generate and consume them.
In “Packet Capture and Analysis in Hybrid Environments”, author Lawrence Miller has provided a real treat. He poses a typical network performance problem as a mystery case, solved by the story’s hero by viewing graphs and analyses at many levels from the depths of TCP up to the level of web browsers. You’ll cheer along with the corporate employees as the narrator uncovers the true perpetrator and identifies remedies.
The tool demonstrated for this exploration is Riverbed Packet Analyzer Plus. It uses sophisticated analysis to operate at multiple layers: tracing TCP/IP packets, displaying server response times to requests (see Figure 1), showing the bandwidth used by each application, displaying the stages of transactions, and much more.
Miller shows how a powerful and well-integrated diagnostic tool such as Riverbed Packet Analyzer Plus can derive solutions from raw data. He covers the major components of Riverbed Packet Analyzer Plus and their benefits. Don’t ever look at log files again—instead, choose a diagnostic tool that meets the needs of modern networks and applications.
