Computer consultants shouldn't be "parts-replacers" any more than automechanics should be--there's no point in aimlessly trying a solution before you're reasonably sure you've found one that's going to solve the problem. The authors of HP-UX Tuning and Performance: Concepts, Tools and Methods know this. It's just one of many righteous nuggets of knowledge Hewlett-Packard employees Robert F. Sauers and Peter S. Weygant convey to their readers as they describe good administration practices for HP's Unix variant. The HP-UX operating system serves as the showcase for their knowledge, but much of what's in this book applies to other environments as well.
The first task of the troubleshooter is to figure out what the problem is,a process that involves both looking at the machine (through a variety of measurement and monitoring software) and talking to the users (using interviews to figure out what's wrong and what changes are needed). The authors document lots of diagnostics tools, including GlancePlus, PerfView and a variety of network tools, as well as interview strategies. They explain how various HP-UX conditions manifest themselves in terms of symptoms and provide explicit instructions for solving problems. They also dig into the principles of good HP-UX software design, promoting the idea that the programmer and administrator are on the same team (and indeed, are frequently the same person). --David Wall, amazon.com
Topics covered: Most aspects of getting HP-UX systems to run as efficiently as possible, including performance measurement and assessment, bottleneck identification, CPU load monitors, disk usage monitors, memory analysers, application design and kernel tuning.From the Back Cover:
The “must-have” performance guide for every HP-UX administrator and developer!
HP-UX Tuning and Performance is the first book to take the guesswork out of maximizing HP-UX performance! This book introduces a comprehensive, systematic performance management methodology that addresses every stage in the lifecycle of an HP-UX system. Two of Hewlett-Packard's leading HP-UX performance experts present specific metrics, symptoms, and solutions for each key element of an HP-UX system, including hardware, the OS platform, and application development. Coverage includes:
HP-UX Tuning and Performance introduces the best generic UNIX and HP-UX specific tools for performance management and demonstrates practical ways to instrument HP-UX systems so that your measurements truly represent real-world performance. Whether you're an HP-UX sys admin, net admin, developer, or capacity planner, it's your complete guide to getting all the performance you paid for!
