Installing additional munin nodes Overview

Following up on the article about installing a munin master slice, if you want to monitor additional slices you'll need to install a munin node service on each.


What's a munin node?

A munin node is a data collector for munin that runs on a slice. A munin master will query the node periodically for its data, and then the master will parse that data and graph it. This article is intended for installation of just a munin node on a different slice from the munin master. If you do not yet have a munin master set up, please follow the instructions in the previous article in this series.
