I've been reading Cisco official guide on CS-MARS and found only a sample of such a file. How could it be done in the first place? Can any one show me a sample of how it looks in the spreadsheet ? I would be more interested in adding agents from CSA and Symantec AV.
I don't, but you can use this document to design one on your own. I would start small, say 5 hosts just to make sure you are getting the schema correct.
