Hi Vikas,

On one of your hosts, try doing a 'xe host-datasource-list host=<blah>' 
and 'xe vm-datasource-list vm=<blah>'. This will show you a list of all 
the datasources that can be recorded as RRDs. Not all of them are 
enabled by default, which is probably why you didn't see everything you 
expected. I have no idea whether we capture the same metrics as VMWare 
do, but hopefully the ones we do capture will be enough for you.
Mike
