Quoting from the nworks official announcement:
nworks, an HP OpenView Platinum Business Partner, today announced that the nworks Smart Plug-in (SPI) for VMware has achieved certified integration with HP OpenView Operations for Windows and HP OpenView Operations for UNIX.
nworks provides a comprehensive solution by integrating VMware ESX Server performance, event, state, and configuration into HP OpenView Operations without installing any software to the ESX Servers. The integration of VMware VirtualCenter events into HP OpenView Operations software helps to expand the reach of the nworks solution to a strategic piece of the VMware virtual infrastructure.
nworks’ solution enables real-time virtual machine discovery by mapping virtual resources to physical resources and physical to virtual resources for a complete view of an enterprise’s virtual infrastructure.
