Well, my frontend works in this way.

1) Discover the object that we will monitor -you need to provide IP address, 
community, port- Object can be a router, switch, server, etc, that the 
frontend recognize.

2) Discover what OID and index the frontend will poll.... for example 
the frontend will examine automatically how many interfaces you have and if 
his status is up start polling.
For interfaces i have the following variables: Bits, Bits In, Bits Out, Bytes, 
Bytes In, Bytes Out, Errors, Erros In, Errors OUt, Bandwith Utilization%, 
Discarted frames, Frames In, will be some more :-)) 

3) A 5 minute cron is configured to start the poll. This will save the data a 
database and next to an .rrd. The name of the rrd is determined by a table 
index. ( I can be more precise if you want how internally the frontend work)

With my interface you can create the graph when you need, and specify the date 
from and date to.
Check this example: http://aleg.freeshell.org/example.gif

The variables will depend on the agent, a server with net-snmp will have some 
variables that a switch will not. 
The good news is that I can expand the numbers of variables, just I need some 
knowledge of the mib)

( I am CC the list for information to another interested users )
