1. Monitoring virtual Environment with
2. University is part of the VMware education program We provide virtual machines as a service for student and research projects We have to take care about this infrastructure How does our University uses VMware
4. SNMP Support for ESX hosts is more and more limited. Monitoring with current Open Source solutions are incomplete. Most integration is just available in closed source - we work in public space we love free and open software - “Free as in freedom”
5. Our wishlist for VMware integration ... Provisioning virtual machines and ESX host systems into OpenNMS Monitoring ESX host systems hardware status Getting performance data from vCenter and ESX host systems

7. OpenNMS VMware vSphere vCenter Server VMware ESXi VMware ESXi VMware ESXi Authenticating against VMware vSphere vCenter Server and requesting ticket for ESX/ESXi host system Requesting authentication ticket for direct CIM calls to ESX/ESXi host system Quering the ESX/ESXi host system using the requested authentication ticket
8. Provisioning Wrote VMware-URL-Requisition to import Virtual Machines and Host- Systems into OpenNMS as Nodes During the import we flag Nodes as Virtual Machine or a Host-System We assign Virtual Machines and Host- Systems to responsible vCenter We assign Services for status monitoring and data collection
