I've been in discussion with the Squid folk about getting the Squid MIBs to successfully parse via smilint, and thus into Zenoss for trap processing.
Unfortunately, none of us are expert in MIB syntax, and we'd appreciate some help - I expect quite straightforward changes are required.
There's a bug report at http://bugs.squid-cache.org/show_bug.cgi?id=3795 and the latest MIB definition is at http://bazaar.launchpad.net/~squid/squid/trunk/view/head:/src/mib.txt
It's also been suggested that we should include/implement a set with 64 bit integer definitions if that's something you can help with too.
You can contact me on or off the list - I'm more than happy to coodinate the changes with the Squid people.
