What I notice at a first glance is the huge (compared to the rest) spike
at 19:30.  This causes the rest of the traffic to become virtually

Are you sure there isn't any local traffic involved?  That is, traffic
not going through the router?

Try to figure out if
- there is no traffic that you didn't take into account
- the data returned by SNMP is correct (for instance, you
  could roughly compare it to the output of ifconfig or
  other tools)

Then compare the log files.  If you forget about this spike,
do they more or less show similar numbers?

What happens if you start a huge download.  Do the two graphs
show the same after a while?
