It is not a simple way to start but you will find that your SNMP data
collections are actually held in /usr/OV/conf/snmpCol.conf.  From
memory, I think you will find that although you cannot specify more than
one entry per MIB in the GUI, you will be able to have several lines per
MIB ( one for each instance) if you edit this file directly.  BACK UP
THIS FILE FIRST BEFORE YOU TRY HACKING AROUND IN IT!!!  It's a long time
since I did this so if James comes back and says you can't do this -
believe him!

Cheers,
Jane
