It still WIP (and I'm sure, that not all statistics are properly gathered), but I hope it may help. And I'm still not quite sure, if I'm interpreting some ARC parameters correctly. Just put attached files into /usr/local/etc/munin/plugins. Cheers, Wiktor Niesiobedzki --0023545309740849ab047cbfcbd3--
