By: Tom Ryder

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.

Scheduling checks from the web interface


In this recipe, you'll learn how to manually schedule checks of hosts and services from the web interface, overriding the automatic scheduling normally done by Nagios Core. This can be convenient to hurry along checks for hosts or services that have just been added, or which have just had problems, or to force a check to be made even when active checks are otherwise disabled on a host for whatever reason.

In this example, we'll schedule a check for a service, but checks for hosts can be established in just the same way.

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_all_service_commands and authorized_for_all_host_commands directives in /usr/local/nagios/etc...
