[mrtg] MRTG traffic question

By default, MRTG uses the SNMP protocol to collect performance information
(i.e. traffic) from network devices.

That would mean an SNMP Get request message to the device, followed by an
SNMP response message from the device.  Each message is embeedded in a UDP
datagram, and a UDP datagram can be as small as 64 bytes, and possibly as
large as 65536 bytes.

The bigger the UDP datagram size, the longer the server takes to respond,
and the more traffic generated  <- general statement.

Couple o' good links on UDP datagrams ...

2) http://kahuna.sdsu.edu/~jecruz/compe560/lab_hmwk/lab5/lab5_report.html

My 2 cents worth
