Overview of this book

Nagios Core is an open source monitoring framework suitable for any network that ensures both internal and customer-facing services are running correctly and manages notification and reporting behavior to diagnose and fix outages promptly. It allows very fine configuration of exactly when, where, what, and how to check network services to meet both the uptime goals of your network and systems team and the needs of your users. This book shows system and network administrators how to use Nagios Core to its fullest as a monitoring framework for checks on any kind of network services, from the smallest home network to much larger production multi-site services. You will discover that Nagios Core is capable of doing much more than pinging a host or to see whether websites respond. The recipes in this book will demonstrate how to leverage Nagios Core's advanced configuration, scripting hooks, reports, data retrieval, and extensibility to integrate it with your existing systems, and to make it the rock-solid center of your network monitoring world.

Viewing configuration in the web interface

In this recipe, you'll learn how to view a table of all the objects currently configured for the running Nagios Core instance. This is a very convenient way to view how the system has understood your configuration, which really helps make sense of things if you use a lot of tricks such as object inheritance and patterns for hostnames.

Because it's tucked away at the bottom of the Nagios Core web interface's navigation menu, some administrators aren't aware of this feature. It's very simple to use as there are only really two steps involved.

Getting started

You will need access to the Nagios Core web interface and permission to run commands from the CGIs. The sample configuration installed by following the Quick Start Guide provides the nagiosadmin user all the necessary privileges when authenticated via HTTP.

If you find that you don't have this privilege, check the authorized_for_configuration_information directive in /usr/local/nagios/etc/cgi.cfg...
