Munin is a system and network monitoring tool that generates useful charts of resource usage. The primary goal of the Munin project is to provide an easy-to-use tool that is simple to install and configure and provides information in an accessible web-based interface. Munin also makes it possible to monitor multiple “nodes” with a single installation.

8. Below are some screen shots of the various reports available that you can get to by either scrolling down your main report page, or by clicking on one of the header links such as Apache at the top. You can also click on any of the individual report graphs to be taken to the monthly and yearly reports for that category as well:
