Xen Hypervisor Monitoring with Open Source Zenoss Core

Nice blog posting from Open Source Zenoss at http://feedproxy.google.com/~r/SocializedSoftware/~3/tSQHqVWdS9s/.
This week I am very excited because we released Zenoss Core 2.5.2 with a cool new feature,  Xen hypervisor monitoring.
I am very happy to see Zenoss put this out as open source software, because it’s the beginning of what could be a great piece of software. Now that this is out there for anyone to use I expect to get lots of feedback to extend and improve it.
This extension to Zenoss Core discovers guests on Xen para-virtualized hosts and provides monitoring of performance and availability via SSH. While the Xen hosts run on physical servers, the virtual guests are listed per host and linked back to any discovered instances on the network. Admins can quickly find the associated hosts and guests and monitor their Xen virtual infrastructure along side their entire physical, virtual, and cloud-based IT environment through a single interface.
I really think this is the beginning of a lot of virtualization and cloud monitoring capabilities from Zenoss Core. In recent weeks we got a couple neat extensions for virtualization and cloud monitoring including Amazon Web Services,  Google App Engine, libvirt (a virtualization library favored by Red Hat) and Ganglia integration.
