Hi, You may find some good information in arc_summary.pl script for FreebBSD by jhell: http://jhell.googlecode.com/files/arc_summary.pl
I've also did some plugins for munin, where based on that, and looking on the code, I tried to provide some interpretation of L2ARC/ARC statistics (see attached scripts). I'm still not sure, if I have all the important stuff visible on the graphs.
