As is often the case with open-source applications, the product is fantastic but the documentation not quite up to par. That is where this particular book comes in handy. The author goes through all the details of setting up a Nagios server from the beginning decisions of just where to place the server to the set up of individual objects, notifications, groups, permissions and exactly how to check services and objects. He even goes so far as to discuss how to integrate Nagios into other products such as Snort and developing and writing and plug-ins.
Written in a style that is easy to follow for the average Linux user who is comfortable with the Linux filesystem, editing configuration files, and generally working with the command line. This is not for the new user familiar only with the graphical desktop environment. But for the Linux system administrator with an intermediate level or higher skill set Pro Nagios 2.0 is an excellent resource and is highly recommended.
PN2 is an extremely well-written book. James Turnbull's style is very easy to understand and his message is well thought-out. One of my favorite aspects of PN2 is the author's multiple recommendations. He doesn't just explain options and features; he says what he thinks works best. Turnbull's syntax examples are very helpful and thorough.
I found PN2's approach to be just what I expected and needed. A basic Nagios user could read the first five chapters (Installation, Basic Object Configuration, Security and Administration, Using the Web Console, and Monitoring Hosts and Services) and have a working, capable Nagios installation. The last five chapters (Advanced Commands, Advanced Object Configuration, Distributing Monitoring, Redundancy, and Failover, Integration Nagios, and Developing Plug-ins) address more advanced topics.
I was particularly glad to see security addressed as an important topic. I liked his explanation of why not to use .htaccess files with Apache (p 92-93). PN2 also introduces working solutions for redundancy and failover (topics not explicitly covered in NSANM). The author takes steps to ensure readers really understand Nagios; for example, he explains macros well, while NSANM mentions them without much thought.
I did not encounter any real technical problems with PN2, hence its high rating. I saw the author mention TCP as the transport protocol for SNMP on p 181; it should be UDP.
PN2 is an ideal book for anyone who wants to run Nagios. I believe new Nagios readers should read PN2, and strongly consider NSANM as a complementary reference volume.
With 366 pages this is the most compact Nagios monitoring solutions guide on the marcet. Period !
You can easily take the book with you anywhere you go.
Note however, that Turnbull seems to hit the ground running. The reader is assumed to have at least
some general knowledge of Linux, the command console and roughly how the system works.
Also Turnbull does give a basic function rundown of Nagios in the first 80 pages of the book, it is more
the advanced users that will appreciate the countless documented approaches for monitoring solutions
that are documented in the rest of the book.
He covers a wide range of topics and virtually goes the extra mile. While I found especially the sections
on Security, NRPE, NCSA and SNMP very detailed, the book does really cover a lot of ground in ALL
chapters with a nice mix of details within the text.
Turnbull clearly covers topics which are either not at all or at least not in such detail documented in other
books I have read so far (f.e. failover, redundancy, indirect monitoring, on demand macros, daisy chaining,
adaptive monitoring, freshness checks, the event broker, the embedded perl interpreter, the NSClient++ etc.)
... and the good thing is he doesnt stop there ;-)
Therefore, I would consider Apress's book focused towards software architects, system integrators,
senior system administrators, programmers and developers and I believe it serves this marcet very well.
The books contents is at least 3-6 months newer than other books on the marcet. So simply put, if you are
serious about learning advanced monitoring solutions than you currently have no choice but to get this book.
