[mrtg] MRTG and Cisco NBAR Assistance needed

I am relatively new to MRTG and have run into some trouble getting MRTG
to graph the Bandwidth data on a Cisco NBAR configured protocol.
(Specifically it won't graph the data for http traffic)  Can't figure
out why and I am hoping someone out there can help.  And please don't
tell me to use RRDTool, I realize the general feeling out there is that
it is MUCH improved over MRTG, but we just got permission from
Management to begin implementation of MRTG, so that is what we are stuck
with for now. (Unless we want to wait another 6 months to a year, which
we don't)

Now, I have NBAR configured for several protocols, and all the others
work fine, http is the only one not showing any data in the graph or for
the Max/avg/current fields (shows 0.0 all across for these).  

I have already confirmed the OID for the http protocol using getif and
then walking the tree at . to get the list
of supported protocols. 

By then going to: . I can see the
supported protocol traffic coming IN on interface #2 (FA0/1), and by
refreshing the view I can see that the value for the nbar http oid IS in
fact changing (and thus should be showing in the MRTG graph).  I should
mention that MRTG does not spit out ANY errors, as far as I can see it
is running properly.  I have tried stopping the mrtg daemon, deleting
all the html/PNG/log files created, and then restarting mrtg. Wait for a
few updates and HTTP is still the only one not showing. 

And yes there is http traffic on that port, there is actually more http
traffic than https traffic, which shows up no problem, all of this has
been confirmed by going into the router and viewing the nbar traffic
showing on it  

Anyway, the following is my config file,all lines start at line 1 and
the ip address/community strings have been modified to protect the

(And yes it is on a Win2k machine at the moment (my personal WS), as
this config file is currently in the testing phase, and my supervisor
will not authorize it to be transferred to the collection server until
it is working properly. The collection server itself is running Suse9.0.

Thanks in advance, I hope someone out there can assist me!
