Not that I am aware of. All of the View information should be stored in a database if you can query it through Nagios.
You can get SNMP polling info for your hosts and VMs if you'd like via NMS. Also, if you've got Solarwinds Orion NPM product, you get a ton of great info on the whole VMware environment. You should check out vCenter Operations, which you can get a 30 (60?) day trial for. It's a small virtual appliance that you deploy and interfaces with your vCenter cluster. It gives tons of great information on every aspect of your virtual environment including storage IO.
thanks, I'll try that if I could find a free minute
