Nagios: System and Network Monitoring Book

Nagios is a popular open source computer system and network monitoring application software. You can easily monitor all your hosts, network equipment and services. It can send alert when things go wrong and again when they get better.

The convenience and reliability that monitoring programs offer system administrators is astounding. Whether at home, commuting, or on vacation, admins can continuously monitor their networks, learning of issues long before they become catastrophes.

Nagios, the most popular open source solution for system and network monitoring, is extremely robust, but it's also intensely complex. This eagerly anticipated revision of the highly acclaimed Nagios: System and Network Monitoring, has been updated to address Nagios 3.0 and will help readers take full advantage of the many powerful features of the new version. Ethan Galstad, the main developer of Nagios, called the first edition of Nagios "incredibly detailed." He went on to say, "I don't think I could have gone into that much detail if I wrote a book myself."

Nagios, which runs on Linux and most *nix variants, can be configured to continuously monitor network services such as SMTP, POP3, HTTP, NNTP, SSH, and FTP. It can also supervise host resources (processor load, disk and memory usage, running processes, log files, and so on) and environmental factors, such as temperature and humidity. Readers of Nagios learn how to:

  • Install and configure the Nagios core, all standard plugins, and selected third-party plugins
  • Configure the notification system
  • Program event handlers to take automatic action when trouble occurs
  • Write Perl plugins to customize Nagios for unique system needs
  • Quickly understand Nagios data using graphing and visualization tools
  • Monitor Windows servers, SAP systems, and databases

This dense, all-inclusive guide to Nagios also contains a chapter that highlights the differences between Nagios versions 2 and 3 and gives practical migration and compatibility tips. Nagios, 2nd Edition is a key resource for any system and network administrator and will ease the pain of network monitoring migraines in no time.

Wolfgang Barth has written several books for professional network administrators, including The Firewall Book (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.

Suse Linux: Nagios Basic Installation and Configuration

Nagios is my favorite open source server and network monitoring application software. It watches hosts and services that you specify, alerting you when things go bad and again when they get better.

If you're planning on installing Nagios, check out this installation guide from Rainer Brunold that gives you step-by-step instructions on how to set it up:

Nagios is a popular host and service monitoring tool used by many administrators to keep an eye on their systems.

Since I wrote a basic installation guide in Jan 2006 on Cool Solutions many new versions were published and many Nagios plugins are now available. Because of that I think it's time to write a series of articles here that show you some very interesting solutions. I hope that you find them helpful and that you can use them in your environment. If you are not yet and nagios user I hope that I can inspire you and you give it a try.

I don't want to write here a full documentation about Nagios, I prefer to give you a basic installation guide so you can set it up very easy and play with it yourself. The installation guide will show you how to install Nagios as well as some interesting extensions and how they integrate into each other. During this installation you will make many modifications to the installation that will help to understand how it works, how you can integrate systems and different services. I will also provide some articles about monitoring special services where I describe what they do and what configuration changes are needed. All together should give you a very good overview and documentation on how you can enhance the Nagios installation yourself.
