Nagios Core Administration Cookbook

Good Technical content ... Will recommend to next customer ....

Good for a variety of Nagios levels - needed if you want to administer nagios core. Having available for kindle/app is a bonus.

I don't know why everyone is giving this a 5 star rating. It's basically a copy/paste of the Getting Started Guide that is online. The first pages are wasted on showing you how to add hosts, services, contacts, host groups, service groups and contact groups to the config files...Every single example in here use Linux computers. In the real world, most people have Windows machines they need to watch as well. Never touched base on use the ++ client for windows (which is okay I guess because it's just 1 more program to hog memory on a windows box).This is definitely a book for absolute beginners, no more than that. I read the whole book after receiving it last night in an hour... if that is any indicator.What I was hoping for as a "cookbook" were real world examples using Linux and windows machines and maybe a few popular networking products like Linksys and Cisco using SNMP and WMI or something else to get the data you need.I was very disappointed in this book. It never met my expectations as a "Cookbook" and was feeling scammed when it it is just re-spouting the same stuff from the getting started guide online.FYI: Here is a free one... [...]

I've involved in a cloud development project. I use Nagios core for monitoring servers and devices in this project. As we know, Nagios is one of famous open sourced monitoring tools. I needed references in dealing with Nagios. While I was reading this, it remind me of basic concept of Nagios again.There are some sections in every chapter. "How to do it" , "How it works" and "There's more". it describes how we start a certain feature of Nagios according to the section in "How to do it" and then explains its mechanism with easy way in "How it works" and finally there is additional contents related to the chapter in "There's more"There is impressive paragraph in the book that nagios is close to MONITORING FRAMWORK rather than monitoring tool. It is perfect that describes nagios characteristic because it has already provide ecosystem, for example, lots of plugins support . And it is important to know where to find if need specific plugin that doesn't meet requirements. Author instructed that how to find a plugin that the administrator needs and where.People who are unfamiliar with Nagios, in my opinion, they may be confused that Nagios has SOFT and HARD state in response to server or host failing. In chapter 3, author tries to explain the difference between two by giving an understandable example.At last, in chapter 11, he gives an explanation about add-on projects like NRPE, NSClient++, NDOUtils and SNMP trap. If you need to extend the feature of Nagios to provide better-fitting solution on you own production, this will very helpful to you.

This book is really well written and walks you through all aspects of Nagios from getting started to advanced topics such as configuring a redundant server. I have been using Nagios for many years and was surprised that I was able to expand my knowledge and develop a better understanding of topics I had previously struggled with. The author also does a great job explaining difficult concepts in a simple way that make it easy to understand. The format is a little odd, each of the topics are written as recipes of a cookbook of Nagios mastery. However, this actually seems to be a good way to dissect Nagios into small parts that are able to be easily understood. Each recipe also gives back and forward references to materials you might want to look at first as a prerequisite or afterwards to expand the concept. There are also lots of references to external content if you wish to learn more about specific topics that are covered briefly in the book. I recommend this book to anyone looking to get started with Nagios or to people who wish to expand their Nagios knowledge.

I have to say, most of my knowledge of Nagios comes solely from surfing the internet, trial and error, and Google. I wish I had this book over a year and a half ago when I first started learning about this software. The topics are extremely easy to follow and start from the very basics to advanced topics including redundant servers and monitoring Nagios own performance. The illustrations that accompany the text are very easy to follow and understand and help, rather than hinder, the information. I really like the way the book is laid in terms of chapters and sections - new information is presented, explained, and detailed, but then there's a section called "There's more..." which delves deeper into the specific topic. In all, for sys admins and others who wish they could monitor their networks in real-time and be more proactive, this book is an invaluable source and constant companion. I can't recommend this book enough. More information about this book can be found here - [...]. Do yourself a favor - save yourself the headaches, the constant Googling, and headscratching and pick up this book. You'll thank yourself in the end.

This book covers every corner of Nagios Core needed for a healthy setup. If this is your first time using Nagios Core, this is the book for you. Even if you have a working environment, this is a great resource to verify best practices are being followed - in terms of both security and usability.I recommend going through this book while configuring Nagios Core in a lab environment, especially if this is your first time. I was going through the recipes with a spare machine running Ubuntu Server 12.04 LTS.

There have been some good books written on Nagios, however, they are dated! This is current and up to date with applicable examples. If you are looking for a good 'how to' for Nagios, this is a great place to start!

If you are a sysadmin and you want to set up a Nagios install fast but correctly so you don't have to re build it properly later then buy this, everything you need in is there... Simples!
