Far and away the best book on Nagios
By AXEV8WGL08CNY on 2007-05-31
I use Nagios heavily at my company and as a result, I've purchased all of the available texts on the subject. This one is simply the best work on Nagios available right now. It's clear and succinct where even the online docs from the Nagios project can be confusing. It covers things that the No Starch volume barely touches on (WMI Scripting and Nagios) and honestly, the diagrams and code samples are clear and useful in real-world application.
Really, buy this one. If you need another one, I would be surprised.
An excellent work on the overall scope of network monitoring
By A3FISKIACEXKOO on 2007-03-13
Nagios already has extensive online documentation and one of the best and most active communities, so why do you need this book? You need it because it is most assuredly not an attempt to simply rehash existing documentation.
This book does a great job of addressing the challenges involved in deploying Network Monitoring generally, and then providing the reasons why Nagios is the best choice for providing the needed functionality, and how to go about making sure your implementation is a success.
Best of all it is not a dry technical reference tome. Such things have their place, but what seems to be more lacking in a lot of systems administrators is a deeper more cohesive understanding of how it all works together, and why it works that way. This book presents that information in a way that is easy to read. The author's personality quite clearly shines through in most of the book, making it rather easy and even enjoyable reading. Something that sadly is often lacking in many of todays over-edited technical works.
The author punctuates his points where necessary with easily understood examples that drive the point home, and help to communicate the scope of the issue with potential impacts. Most any seasoned Nagios administrator will recognize at least variants on many of the examples he uses as incidents from their own history.
One other point worthy of mentioning is that he is quite clearly not afraid of the manual administration of Nagios. There is a weird trend among some *nix administrators these days that says if you can't click through a few forms and be done then it's too hard. This book not only doesn't shy away from this, it takes the time to explain why this is exactly what we don't want.
If I could recommend improvements for this book, it would be to include a full case study on deploying Nagios in an environment. Mapping the network, examples of the management involvement he describes, the structure and content of the resulting config files and notification schemes, and so on. Perhaps then with a series of changes describing the way Monitoring systems tend to change over time. Responding to needs for an on-call rotation, people whining about the number and types of pages they receive, etc. Perhaps the addition of another network segment or location, or a recurring situation that requires the creation of an event handler to manage. This would round out the end of the book well and help to draw all the presented concepts together for the reader.
Regardless, if you're thinking, are in the middle of, or have already implemented a monitoring system I highly recommend this work. Even seasoned Nagios administrators may benefit from the reading of alternative approaches and more recent features available through Nagios - such as performance metrics and the event broker.
Spot on for a well structured book with many WOW-factors

The book is with 190 pages (230p. when including appendix and index) very compact. It teaches you Nagios in a way I have never heard / read before. I must assume that the authors clear structured style - which runs through the book like a red line - must be responsible for the excellent outcome.
The book starts in the introduction with the title "Do it right the first time" and that hits it right on the spot. What make out the features of this little portable knowledgebase is the exceptional well thought through contents and its explanations by the author. David is not filling pages by explaining each and every parameter, but rather showing you the big picture, and explaining how to approach new issues or how one technical solution is better over another.
This is the book you should pass to your manager so (s)he understands why and how an open solution like Nagios is the better choice and can be used for achieving surpassing solutions.
The book itself basically is divided in two sections:
Background, setup and configuration - Chapters 1-5
Advanced Topics - Chapters 6-8
I did find any of the chapters to have a nice balance of the amount of information needed but some EXCEPTIONAL good parts of book where:
Chapter 1 Best practices
Chapter 2 - the part about scheduling
Chapters 6-8 as a whole
Chapter 6 has a thorough explanations on monitoring the different OS's (especially the Windows part !!) or other applications.
Chapter 7 for its overall thoroughness of how to visualize your data to reach the next level of a better understanding of the systems / network you are monitoring.
Chapter 8 is describing a filesystem based status interface. The NEB module will write a file with its current status code for each service. I have to admit that some technical details went over my head, but I thought that was pretty cool !!
The featured points above is what I found to be exceptionally good and most likely the strongest sales points for this little portable knowledgebase. That doesnt mean that the other not mentioned parts of the book are weak, mind you.
Funny enough the above mentioned points where EXACTLY the points which I havent seen explained this thorough anywhere before.
So David's book was exactly spot on for me.
Summary:
To sum it all up in very simple words: This is a hell of a book !!
Its the most compact, well structured book on Nagios that I have seen to date. It contains many WOW-factors. While reading each chapter you can virtually "feel" how Davids explanations and tips and tricks already helped you to avoid time consuming pitfalls.
So this book is not about "to buy or not to buy", this is an investment you dont want to miss !!
I was especially impressed by the thoroughness the book is written by from the first page. Also the contents of the first chapter wasnt new to me, the way it was explained already provided many of those A-ha moments.
The main asset of the book is not the description of the tools itself, but rather the tought and considerations the author put into it and the sharing of those thoughts in a way that the reader can actually visualize how and why one solution is better over another, without actually having to go to the "luxury to experience the pitfalls" in a live disaster scenario.
PS: AFTER I finished reading the book I re-read the "Editorial Review" Amazon gave above and found it pretty well describing the actual book and what you should expect.

Not Much More Thorough Than Existing Documentation
By A2OH11RXZJDOEV on 2007-09-24
It's well written, but it didn't provide much more insights and coverage than reading the existing documentation you can download for free. There are also some glaring gaps in its coverage. There's nothing about passive checks! And I don't think it was written before v3.0 came out.
If you like written docs for stuff you reference often, it will be worth the money. But don't go to it with any significant troubleshooting problem.
Good for quickstart
By A3GCGXNKLB4X1A on 2008-03-01
Main benefit of this book is that it will teach you many things in a short time. You might want to purchase it if you want a quick start on Nagios, and don't plan to use Nagios on larger systems. Also, although the author's (brief?) style has some benefits, it also has some drawbacks.
Things like distributed monitoring, fail-over, passive checks,... are barely touched. If you are installing Nagios for the first time, you probably won't miss these subjects elaborated, because you will want to have it running soon as possible. However, I think the Apress book covers these advanced topics much better, and gives a more comprehensive overview of Nagios. The decision is up to you. I preferred the lengthier book with more things explained, although it was a bit harder to read.
One more thing that I disliked was that for Passive checks author references Chapter 2. I couldn't find anything about passive checks there, so I checked the Index. No mention of them there either. I gave this book a relatively bad review due to this kind of unclear issues and for the lack of distributed monitoring and failover coverage, which I think is very important for a monitoring system in a serious installation.
As said, some things are better in this book than in Apress one (like ie. Windows check explanation), but in general, Apress book left a better impression on me.
