Here's an old article by Duncan Epping regarding vSCSI IO Stats: http://www.yellow-bricks.com/2008/06/19/vscsi-stats/

Internally, we use this tool quite a bit to quickly analyze workloads to understand their characteristics. Analysis that used to take hours takes seconds now. I wrote a paper accepted at IISWC 2007 that you can take a look at. Also, at my blog you can find some more related stuff. Surf on over to http://virtualscoop.org.

Feel free to ask more questions here or at my blog about the tool and what kind of stuff you can do with it.

Thanks to both of you. Have any script examples you can share? I simply want to export it to csv really. There is so little documentation available for this tool.....

The tool has an option to export csv natively. Just run -h and read the help.
