Learning Nagios 3.0 is a new book from Packt that will introduce Nagios to System Administrators who are interested in monitoring and maintaining their systems. Written by Wojciech Kocjan, this book will help users understand how Nagios works, and help set up and configure its latest version.

Nagios is a popular open source computer system and network monitoring application software. The main purpose of system monitoring is to detect and report any system not working properly as soon as possible—so that a system administrator is aware of problems before a user runs into them. This is where Nagios is needed to constantly check other machines and various services on those machines.

System administrators will learn to secure their systems in a much improved manner incorporating the newer features of Nagios 3. They will learn to deploy agents and plug-ins, monitor assets, and notify users of current and future incidents to protect the availability, performance, and security of monitored assets. Professionals working on earlier versions of Nagios will come across new features like inheritance and also the new internal functions like better check scheduling.

Users will be taught to set up a working and usable distributed monitoring system using NSClient++ and NC_Net. They will also be able to host check results over the network using NSCA and develop custom plug-ins responsible for doing the checks and analyzing results. Users will also learn to use SSH, NRPE and SNMP for doing remote checks and to retrieve information from a device, set options, and also cover means for a device to notify other machines about a failure.

System administrators wanting to learn about version 3 of Nagios will find this book useful. The book is out now and is available from Packt. For more information, please visit http://www.packtpub.com/guide-for-learning-nagios-3/book
