Nagios Core Administration Cookbook - Second Edition

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.

This recipe is useful in situations where a particular user requires information on the status of certain hosts and services but should not be allowed to view others. This is a setup that can't be managed with the directives in cgi.cfg.

As a simple example, on a given monitoring server, we might have two hosts configured as follows:

define host {
    use        linux-server
    host_name  sparta.example.net
    alias      sparta
    address    192.0.2.21
    contacts   nagiosadmin
}
define host {
    use        linux-server
    host_name  athens.example.net
    alias      athens
    address    192.0.2.22
    contacts   nagiosadmin
}

We might like to add a new user athensadmin with permissions to view the status of and run commands on the athens.example.net host and its services but not the sparta.example.net host or its...
