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.

For companies with more than one person as dedicated network staff, it's common practice to have an on-call roster, where one member of staff will be the dedicated on-call person for a certain period of time, perhaps a week or two. The kind of setup we'll configure here allows filtering notifications so that they're only delivered to the contacts at appropriate times; notifications are generated by hosts and services and sent to all the contacts in the nominated group, but only one (or perhaps more than one) of the contacts actually receives it.

We'll set this up using two properties of contacts that allow us to restrict the time period within which they should receive notifications: host_notification_period and service_notification_period.
