What we do with VMware ... ... part of the VMware education program We provide virtual machines as a service for students and research projects We have to administrate the virtualization infrastructure 3 Monday, July 2, 12 

What we do with OpenNMS ... Monitoring the network infrastructure Failure management Service assurance Collection of performance metrics for capacity management 4 Monday, July 2, 12 

Why OpenNMS? Java based enterprise grade network management platform 100% Open Source (GPLv3+) Java provides a VMware-Infrastructure library OpenNMS as a platform, provides APIs for network management tasks Provide students possibilities to learn in large software project - Google Summer of Code 2012 5 Monday, July 2, 12 

Why we developed the integration? SNMP Support for VMware infrastructure is very limited compared to VI-API Open Source solutions provide scripts for just a few monitoring tasks Most integration is just available in closed source - we work in public space and prefer free and open software - “Free as in freedom” 6 Monday, July 2, 12
