[Observium] wmi calls

Hi all, I'm trying to get observium work with some of our windows servers, particularly for mssql and exchange stuff. Couple of Q's - Exchange - it's not pickup up any data, but maybe this is because we're using 2003 - is this "supported". I use the quotes as the wmi stuff is listed as very much in development so possibly not working.. MSSQL - again no data, all zeros like with exchange.

I tried the polling.php wmi specific command, but I can't see any wmi stuff particularly - just the standard snmp.

Thanks in advance andy
