Munin helps you see the trends in your server resource usage. This allows you to predict bottlenecks in advance. When faced with a problem, you can compare the current behaviour to historical data. Munin had a major "minor" release in 2009, which introduced new features. Next release is a new major release, with even more features. One of the features of Munin is how it can feed events to Nagios. Munin sends these events whenever a value crosses a predefined limit. Events are sent from Munin to Nagios, and are configured as passive alerts.
This talk will recap some basics of Munin, present recent features and the roadmap for the next release, look at how you can improve the performance of a munin installation and talk about integrating Munin with Nagios.
