In Detail

The real challenge of performance issues comes from trying to get to the root of the problem.

Having a monitoring system set up makes your life, as a system administrator, a lot easier.

The Munin Plugin Starter is a practical, hands-on guide that teaches you how to set up and monitor your network. Through a simple step-by-step process you will learn how to monitor other devices in your network and learn to write your own plugins. By the end of the book you will have the skills and the confidence to write plugins for any day-to-day task.

This book breaks down monitoring with Munin into small, easy-to-follow steps.

It starts by setting up a webserver to act as a Munin master and ends by teaching you how to write a custom plugin by yourself.

Learn how to configure Munin nodes to monitor servers and other devices in your network. This will make it easy to monitor switches, printers, or any other device attached to the network.

If you want to learn how monitoring gives you insight into your network, the Munin Plugin Starter is the book for you.
