Something like cache hits/misses, etc. You can do graphs for many things from sysctl kstat.zfs.misc and vfs.zfs I am personally graphing for example: kstat.zfs.misc.arcstats.size kstat.zfs.misc.arcstats.c vfs.zfs.arc_meta_limit vfs.zfs.arc_meta_used But there are other useful values. It depends on usage of the server. Miroslav Lachman
