I have been working with HP OpenView Products for approx. 4 years. Following are the products I have deployed / configured for various clients.

Operations for Unix (OVOU)
Operations for Windows (OVOW)
Network Node Manager (NNM)
OV Reporter (OVR)
Service Information Portal (SIP)

Most of my experience is within OpenView Operations for Unix, deploying and configuring agents and SPI's, and developing custom application monitoring.
