I can share a munin plugin for monitoring some of ARC L1/L2
statistics, as well as memory decomposition.

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,
