This is probably most directed toward PJD, as he did directed the porting effort of zfs to freebsd. There are many read only sysctl handles to L2ARC and L1ARC caches, as well as performance stats. Some of these are self explanatory based on their naming conventions, however some are more vague than others. Could I perhaps get a detailed explanation of what those sysctls related to zfs actually are describing? I'm hoping to build a decent web interface with RRDTool that has accurate and useful information in regards to ZFS performance monitoring. Storage analytics are becoming an increasingly popular trend and are EMC's advantage over something like FreeNAS. My efforts are to make a nanoBSD based distro for NAS systems, but aim at different goals than FreeNAS (for example, including built in HAST support). I'm not sure if I'm going to use m0n0wall's framework or start from scratch, still evaluating which endeavor will be best to maintain and fit the job. Anyway, any explanation would be appreciated, even if you're not the great PJD :-p.
