Complete Web Monitoring: Watching Your Visitors, Performance, Communities, and Competitors ReviewThis book will change the way you think about your online business. From page performance, to conversions, to user experience, to social media, "Complete Web Monitoring" covers the gamut of tools, techniques, and services that exist today to help you truly optimize the success of your online business.
The book breaks down all online business into four categories: Media, Transaction, Collaboration, and SaaS. Throughout the book, as you learn about the various flavors of analytics, usability, surveys, page performance, monitoring, online community management, collaboration...and how all of this fits together...you are given specific, direct, and actionable steps to take that apply to your specific business model. For example, "Transaction" businesses must focus on conversions, uptime of the checkout process, and what customers are saying about their products. "SaaS" companies should focus on the performance of their most common paths through the application, popularity of specific features, and the user experience of the holistic product.
The amount of data and the number of tools at your disposal are overwhelming. At times this book is rather overwhelming. Choosing between an analytics provider, a monitoring service, or a social media tracking service could keep you from actually accomplishing real work. Sometimes too much choice and too much data is a very dangerous thing. It's important to remember to step back, remember the goals behind your measurements, and focus on solving the problems of your customers. With that in mind, the lessons learned in this book will help you zero in on optimizing those end goals.
"Complete Web Monitoring" is valuable for the same reason it is difficult to categorize. The various tools and services that you learn about are generally used by many different departments across an organization, all for very different reasons, generally without any sort of collaboration. What you realize reading this book is that there is a lot more to the success of your business than the limited visibility you get from using these tools independently. To truly understand how your business is doing, and how you can improve not only revenue but also how you build your business, you need a holistic picture that includes data from numerous sources. "Complete Web Monitoring" gives you more then anything I've come across previously in giving you the tools, pointing you to the techniques, and teaching you to focus on what is most important.Complete Web Monitoring: Watching Your Visitors, Performance, Communities, and Competitors Overview
Do you really understand your online presence? Are you confident that visitors can use your website? Do you know their motivations? How do online communities perceive your company? To innovate and adapt your business quickly, you must know the answers to these questions.Complete Web Monitoring demonstrates how to measure every aspect of your web presence -- including analytics, backend performance, usability, communities, customer feedback, and competitive analysis -- whether you're running an e-commerce site, a community, a media property, or a Software-as-a-Service company. This book's concrete examples, clear explanations, and practical recommendations make it essential for anyone who runs a website. With this book you will:



Discover how visitors use and interact with your site through web analytics, segmentation, conversions, and user interaction analysis
Find out your market's motivations with voice-of-the-customer research
Measure the health and availability of your website with synthetic testing and real-user monitoring
Track communities related to your online presence, including social networks, forums, blogs, microblogs, wikis, and social news aggregators
Understand how to assemble this data into clear reports tailored to your organization and audience

You can't fix what you don't measure. Complete Web Monitoring shows you how to transform missed opportunities, frustrated users, and spiraling costs into online success.

I'd like to make this book required reading for every employee at Gomez." -- Imad Mouline, CTO of Gomez

Nagios: System and Network Monitoring ReviewI recently received review copies of Pro Nagios 2.0 (PN2) by James Turnbull and Nagios: System and Network Monitoring (NSANM) by Wolfgang Barth. I read PN2 first, then NSANM. Both are excellent books, but I expect potential readers want to know which is best for them. The following is a radical simplification, and I could honestly recommend readers buy either (or both) books. If you are completely new to Nagios and want a very well-organized introduction, I recommend PN2. If you are somewhat familiar with Nagios and want detailed descriptions of a wide variety of Nagios plug-ins, I recommend NSANM.
NSANM strengths lie in the depth of coverage of certain elements when compared to PN2. PN2 devotes 7 pages to host checks, while NSANM's Ch 7 offers 21 pages. PN2 supplies 8 pages on service checks, but NSANM's Ch 6 gives 46 pages. This level of detail can be very useful. For example, NSANM's explanation of check_squid also shows to to configure Sguid to allow access to its cache manager.
NSANM shares more information on certain background protocols like SNMP. PN2's SNMP section is about 7 pages, whereas NSANM's Ch 11 is 36 pages. NSANM demonstrates more aspects of Nagios' Web interface and the CGI programs generating pages. I thought author Wolfgang Barth made very effective use of diagrams, like the network topology explanation in Ch 4, the service checks in Ch 5, and notification in Ch 12.
NSANM includes some material not mentioned in PN2, like using Nagios with Cygwin. Sometimes the books are very complementary, as shown by PN2's discussion of NSClient++ and NSANM's overview of NSClient and NC_Net.
NSANM is lacking coverage of security, redundancy, and failover, however. PN2 does address these critical issues. Beware the some of the "chapters" in NSANM are very short -- like Ch 8 (2 pages!) and Ch 19 (barely 6 pages). I think short sections like those should have been integrated into longer chapters or moved into the appendices.
Overall, NSANM is a very good book. I believe new Nagios readers should read PN2, and strongly consider NSANM as a complementary reference volume.Nagios: System and Network Monitoring Overview
Good system administrators recognize problems long before anyone asks, "Hey, is the Internet down?" Nagios, an open source system and network monitoring tool, has emerged as the most popular solution for sys admins in organizations of all sizes. It's robust but also complex, and Nagios: System and Network Monitoring, 2nd Edition, updated to address Nagios 3.0, will help you take full advantage of this program.

Nagios, which runs on Linux and most *nix variants, can be configured to continuously monitor network services such as SMTP, POP3, HTTP, NNTP, SSH, and FTP. It can also supervise host resources (processor load, disk and memory usage, running processes, log files, and so on) and environmental factors, such as temperature and humidity. This book is your guide to getting the most out of this versatile and powerful monitoring tool.

Inside Nagios, you'll learn how to:
Install and configure the Nagios core, all standard plugins, and selected third-party plugins
Configure the notification system to alert you of ongoing problems-and to alarm others in case of a serious crisis
Program event handlers to take automatic action when trouble occurs
Write Perl plugins to customize Nagios for your unique needs
Quickly understand your Nagios data using graphing and visualization tools
Monitor Windows servers, SAP systems, and Oracle databases

The book also includes a chapter that highlights the differences between Nagios versions 2 and 3 and gives practical migration and compatibility tips. Nagios: System and Network Monitoring, 2nd Edition is a great starting point for configuring and using Nagios in your own environment.
About the AuthorWolfgang Barth has written several books for professional network administrators, including Firewall (Suse Press), Network Analysis (Suse Press), and Backup Solutions with Linux (Open Source Press). He is a professional system administrator with considerable experience using Nagios.
