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. Cheers, Wiktor Niesiobedzki 2010/3/10 Adam Stylinski <stylinae@mail.uc.edu>: > I wasn't sure what the most appropriate mailing list to address this problem > would be, so I'll go ahead and ask it here.
