Ross Williams	a88d2e313d	Refactor common OpenZFS sysctl access ... Darwin and FreeBSD export zfs kstats through the same APIs, so moving functions into a common file.	2019-07-07 23:10:54 -04:00
Ross Williams	070fe90461	ZFS arcstats for Linux ... If no pools are imported (ARC size == 0) or the ZFS module is not in the kernel (/proc/spl/kstat/zfs/arcstats does not exist), then the Meter reports "Unavailable".	2019-07-07 22:57:15 -04:00
Ross Williams	a93edde1a2	Support ZFS ARC stats on FreeBSD ... New meter displays same ARC stats as FreeBSD top(1). Can be extended to other platforms that support ZFS. Pulling kstat.zfs.misc.arcstats.c_max as the meter total, so the meter has a meaningful value to work up to. The Text meter displays, first, the maximum ARC size (Meter.total), then second, the total ARC used, using the difference between Meter.maxItems and Meter.curItems to "hide" the used value from the Bar and Graph drawing functions by using an index in Meter.values[] that is beyond curItems - 1, but less than maxItems - 1.	2019-07-07 22:52:04 -04:00
