This article will walk you through Installing and configuring the basic Ganglia (a scalable, distributed monitoring system for high-performance clusters) setup. It will also show you how to use the Python modules to extend functionality with IPMI, and how to use Ganglia host spoofing to monitor IPMI. The goal is not only to set up a Ganglia high-performance Linux cluster monitoring system, but also to add more monitoring capability by writing simple Ganglia plug-ins.
