Recently, the Ganglia project, an open source, scalable, distributed monitoring system for high-performance computing systems, announced that it has released version 3.1. Deployed on thousands of computing clusters worldwide, organizations like University of California, Flickr and Stanford Linear Accelerator are using Ganglia to improve performance and get greater configuration options.
Ganglia also happens to be another open source project that has a connection to Novell, as one of Novell's senior software engineers, Brad Nicholes, is also a developer on the project.
