Tom Ryder - Nagios Core Administration Cookbook

Tom Ryder is a systems administrator and former web developer from New Zealand. He uses Nagios Core as part of his "day job" as a systems administrator, monitoring the network for a regional Internet Service Provider. Tom works a great deal with UNIX-like systems, being a particular fan of GNU/Linux, and writes about usage of open source command line development tools on his blog Arabesque : http://www.blog.sanctum.geek.nz.

Thanks are of course due to Ethan Galstad and the Nagios Core development team for writing and maintaining Nagios Core, along with the reference manual against which the book's material was checked.

Thanks are also due to my loving partner Chantelle Potroz for her patience and support as this book was being written, and to my employer James Watts of Inspire Net Limited for permission to write it.

Thanks also to Shreerang Deshpande and Kedar Bhat from Packt for their patience and technical guidance during the book's development.

Emmanuel Dyan is an expert in web development and in all the technologies gravitating around the Web: servers, network infrastructures, languages, and software.

He has been managing his own company, iNet Process, since 2004. He opened a branch in India in 2006 for its development needs, and recruited the staff. He then had to define the working procedures as well as the tools and set up the work environment. iNet Process implements and hosts CRM solutions based on SugarCRM. Its clients are mainly from France and are big, medium, as well as small companies.

Emmanuel teaches development languages, IT strategies, and CMS (Drupal) in a French University (Paris-Est Marne-la-Valle) for students preparing for a Master's degree.

John C. Kennedy has been administering UNIX and Linux servers and workstations since 1997. He has experience with Red Hat, SUSE, Ubuntu, Debian, Solaris, and HP-UX. John is also experienced in BASH shell scripting and is currently teaching himself Python and Ruby. John has also been a technical editor for various publishers for over 10 years specializing in open source related books.

When John is not geeking out in front of either a home or work computer, he helps out with a German Shepherd rescue centre in Virginia by fostering some great dogs or helping the centre with their IT needs.

I would like to thank my family (my wonderful wife, Michele, my intelligent and caring daughter Denise, and my terrific and smart son, Kieran) for supporting the (sometimes) silly things and not so silly things I do. I'd also like to thank my current foster dogs for their occasional need to keep their legs crossed a little longer while I test things out from the book and forget they are there.

Pierguido Lambri has more than 10 years of experience with GNU/Linux and with the system administration side. He has worked with many operating systems (proprietary and open source), but he's a fan of the open source movement. Interested in everything that has to do with IT, he always likes to learn about new technologies.

Thanks to Abhishek Kori and Kedar Bhat for the opportunity of the book review.
