This type of system is far more desirable from an operational  
standpoint, as it provides insight into behavior over time.  Snapshots  
of this type of information aren't very useful at all, IMHO; what's  
useful is to understand trends, rates of change, et. al.

If you're determined to use SNMP and snapshots, you may wish to take a  
look at the NetFlow MIB, which lets you get a snapshot of the NetFlow  
table.  But I very strongly recommend you re-evaluate the utility of a  
NetFlow-based system for this type of application, perhaps starting  
with a freeware tool such as Stager.
