Book Description
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.

A nice solid Nagios introduction a la No Starch Press,
By Nils Valentin (Tokyo, Japan) - See all my reviews
This review is from: Nagios: System and Network Monitoring (Paperback)
Bookspecs:70+ plugins described !! 464 pages The book (in a typical No Starch Press style) gives a clear, concise rundown about Nagios in general. As such it is a well written and sound introduction to the Nagios topic. After having read No Starch Press*s Nagios book you will know exactly how Nagios works inside. The thorough explanations, flow charts and many tips and tricks leave no doubt that after you finished the book you know your way around any Nagios installation. What is remarkable is, that even though the Nagios topic is fairly young, the authors manage to describe more than 70+ plugins. !! One of the features of this book was for me basically a new level of "Usability" - or should I say "reading quality" ? The text contains virtually "links" to related or refered to sections in other chapters. That allows the reader to quickly jump back and forth to follow up on something. A BIG time-saver and from my point of view much appreciated. Beginners or junior system administrators will find No Starch Press's Nagios book an excellent choice. It doesnt come with all the latest bells and whistles but it certainly covers more than 80% of what the average joe sysadmin needs to know. [...]

Best for Nagios admins who want specific details on plug-ins,
By Richard Bejtlich "TaoSecurity" - Published on Amazon.com
This review is from: Nagios: System and Network Monitoring (Paperback)
I 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. 3 of 3 people found the following review helpful

This review is from: Nagios: System and Network Monitoring (Paperback)
Every question I've had has been explained in this book. I followed the online documentation to do a new 3.x install on Ubuntu, and everything I've wanted to do since then has been explained simply, with examples, in the book.
