Hi all,
Well after 3 days of battling with this I have finally joined the mailing list and am throwing my difficulties out there to see if anyone else has found a way to overcome them, or maybe the problems I'm having are self-made ( I'm not as think as you Dumb I am!) anyway onto the problems.

First, I have a firewall device in my primary office, I just want to monitor the bandwidth usage on the DMZ, LAN, and WAN interfaces, now for the Best part, It's a SonicWall Pro 200. (yes, yes I know a stroke of genius buying that one).  Anyway its running firmware version 6.4.2.0 I've use SNMPGET and SNMPWALK command to retrieve the info from the sonic wall and when I pole the ifInOctets.x and the ifOutOctets.x It returns 0 for all except for .2 that return some 45 million something (my heart skipped a beat as I thought hot damn I've got a DS3 and didn't even know it), well after observing the .2 for a while I realized the number wasn't changing at all, so my plight continued, I then scoured the web for possible solutions, including the archives for this list.  I shortly found some information telling me to download the MIB files for the particular sonicwall and firmware I have (I was so sure my life was going to get better after this).  I put the files on my mrtg machine added the LoadMibs: /bla/blahblah/blah/POS-sonicwall.mib to my mrtg.cfg and ran mrtg manually a few time....nothing, I have grids with no plotted data...*sigh*, I actually spent some time reading the sonicwall mib's, I must say they are nearly completely worthless, unless you may want to set a trap to you know when someone tries to hit you with a Subseven attack that by the way the sonicwall blocks automatically.  At this point I decide to let that bugger rest a while and move on to one of the firewall devices at one of our sattelite locations, guess what kind of firewall's these are... here's a hint they are the only kind that work with a sonicwall pro 200's vpn....yep thats right more sonicwalls, little soho3's this time....results were the same.  Ok time for a new strategy I decide to try to monitor beyond the Pro 200 at our Cisco router at least then I would be able to see what our total bandwidth usage is for this location.....well its a Cisco 678 and it didn't friggen work either!!!! So now I'm thinking, no way I've screwed up my MRTG install, or my perl install, or something, so I try one last device I setup MRTG to talk to my 3Com Superstack.....worked like a charm.

So am I screwed trying to get the Sonic Walls and this Cisco 678 to talk to mrtg,  I have spent hours looking for MIB's and OID's, I can find tons of MIB's at cisco, but they don't have it broke out by product, how do I tell which one I need?  

Please help me, your my only hope!

TIA!

Brett
