--0015174736727e3eb4048176c9db Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: quoted-printable 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.
