Ganglia

Ganglia for Windows makes it possible to monitor and track live or recorded data and statistics for distributed computing systems setup as simple networks or clusters. It can monitor and record any number of useful metrics or statistics: for example, CPU load averages or network utilization. It is also scalable so that it can manage small to very large networks or clusters. In fact, Ganglia has been used around the world on university campuses to link, monitor, and maintain network clusters with up to 2000 nodes.

Ganglia is a free, open-source network monitoring software developed by a team at SourceForge.net. Still, it is based on software originally developed at UC Berkeley to monitor its own distributed computer clusters. The system is currently used around the world in commercial and educational institutions such as MIT, NASA, Cray computing, and Twitter.

At the heart of Ganglia is a hierarchical design based on dealing with networks as a federation of clusters. Ganglia uses a multicast-based, listen-announce protocol to monitor cluster states. It takes advantage of common technologies to collect, store, and transport data such as XML, XDR, and RRDtool.

The Ganglia distribution contains all the files required to deploy the application to your web server: simply copy files to your server. After installing, Ganglia can be accessed from any computer, smartphone, or tablet in the network. Ganglia is a very robust, efficient, and scalable monitoring system for computing systems distributed in clusters or grids. 

Ganglia is easy to configure, use, maintain and scale-to-needs software that has a small footprint on server performance.
