About the Author
Wolfgang 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.

It includes "parents" on the network to quickly determine what is at fault; so where you get a user bleating "I can't access the Internet" rather than doing your fault finding (check the proxy, check the firewall, check the router, phone the ISP) Nagios will tell you where the fault is before the user even picks up the phone.
It even talks about monitoring the room temperature of the server room and letting you know if there is a fault there.
Many technical manuals don't provide a decent index; this is not one of them! The index is great and on level par with "Unix Power Tools" by O'Reilly.
Linux experience is required to some degree, but don't let that put you off. Most linux distributions are easy to install now and get up and running to run Nagios. If you're not sure what distro to use (and haven't bought a RedHat pre-installed server) then Ubuntu Server is a great place to start and has excellent device driver support.
I don't normally write reviews but this is by far the best technical manaual I have ever read (and I've read a lot) so felt compelled to shout about it from the rooftops - if you're looking to learn Nagios look no further.
If I had one complaint, it is that it does not cover NConf - read this book and then check it out!
For my colleague who is new to Nagios it has given both an understanding of how it works, simple ways to configure it and help with his learning of a whole linux environment.

For problem of version, I also purchased another book named "Learning Nagios 4" (by Wojciech Kocjan), it's very good one too, but I actually found more helps from this one in my daily monitoring job. Maybe it's because of I starting to learn Nagios with this one.
With help of this book, I have achieved to perform real monitoring job within two weeks, I have successfully developed a lot of plugins which are suitable for my customer's applications from scratch. Including NRPE, NSCA etc. It's really helpful.
When you try to install Nagios (now is version 4), those URLs of download from the book are obsolete, what you have to do is to go to the Nagios official web site to download it and then install it by yourself. The same case for NRPE, and NSCA.
I have also found there is some specific command mentioned in the book is not really there. For example the check_command, notify_outage, for distributed monitoring and passive check, I just can't find it any where. Well, I use the check_dummy and it works well for me.
Hope this could be helpful in some way.
2 years back I have read the first edition and was already impressed at that stage. Now the second edition came out with majored and updated contents, wider coverage, more details and - if you want to call it that way - built-in backwards compatibility.
Great care was taken to reflect any changes that had been done between Nagios version two and three. Whenever necessary, Barth's Nagios book points out those changes. As a fact I would say its one of the key features of this second editiion to take the reader from the second version to the third version.
This obviously includes configuration changes, migrations and testing it.
The carefully documented experience of the author and his team alone make this book well worthwhile !!
This goes from the time saving technics he describes, the config changes hints and tips, the migration scenario sample through the more advanced topics mentioned above like distributed monitoring, single sign-on environments, the embedded perl interpeter, all kind of databases (MySQL, PostgreSQL, Sap, Oracle) mailservers ( postfix, qmail, exim, sendmail ) etc. and the list goes on and on.
The now 720p and 26 chapter strong second edition covers the advanced topics many of us have been waiting for.
Just see the below highlight feature list for the big changes of the whopping 200 page additions:
- Whats new in Nagios three (overview)
- Migration / conversion from version two to three
- Single-Sign on environments (Apache, Windows ...)
- Nagios embedded Perl Interpreter
- Distributed Monitoring
- Alternate state flapping
- Monitoring file and folder sizes
- NRPE coverage
- NSClient++ coverage
The book is rounded up with 8 !! Appendices and a 25p index.
I feel you get a lot of information that will save you lots of hassle down the road.
F.e if any of the ready available plugins are not working the way you want it, no problem, Mr. Barth gives you ideas how to make them work for you or even how to create your own.
The authors very accessable style make this book readable and enjoyable for system admins, developers, consultants and managers.
The 1st edition was already ahead of its marcet, but now with Mr. Barths second edition it's definitely the worls best coverage of the Nagios tool !!
Kudos to the author and his publisher team !!
