There is a load mibs directive in the mrtg.conf file. It's documented on
www.mrtg.org in a special section for monitoring squid (off the main
page). I'm not certain that will eliminate the problem, however. I've
put that directive in and I still needed to replace a name with the
oid. If it doesn't work, consider just putting the raw oid in. There
was one site that had a lot of oids for squid. I'll see if I can dig up a
url.

You can skip the rest of this if you get any valid responses.

Make sure your access lists are working. Make sure you're polling the
right port in your config and if public is your community string, you'd be
wise to change it. do an lsof -i | more (mine shows for a solaris box).
squid 29504 nobody 9u inet 0x729f6808 0t0 UDP *:3401 (Idle)

Or use nmap to scan the port to see if it's closed. The port should be
specified in the config. in mrtg you would specify as such
public@192.168.1.0:3401::::

Best thing to do is an snmpwalk on the localhost and see if you get a
response. snmpwalk localhost:3401 (yours may not be on 3401) public
cacheServerRequests or better yet use an oid such as
.1.3.6.1.4.1.3495.1.3.2.1.8.

I hope that helps.
