I have to agree here. SNMP was designed to efficiently get the data
from what you are monitoring, to where you want to store/process it. If you
want to process the data on one machine, use SNMP to get the data to that
machine.
The only reason to collect, compress, and forward the data via
another machine would be if your network topology required it. In this case,
you'd still probably want the RRD's you are processing on the one machine.
There are a variety of ways to achieve this, from collecting, compressing
and forwarding the raw snmp data, through constructing and forwarding the
RRD database itself.
