Check_MK Werk 0992: zfs_arc_cache: returns OK even if values of arc meta are missing

ID: 0992 Title: zfs_arc_cache: returns OK even if values of arc meta are missing Component: Checks & Agents Level: 1 Class: Bug Fix Version: 1.2.5i4 If a ZFS does not report any data about arc meta, the check up to now did return UNKNOWN state. Now in this case it returns OK, because this is a valid state for a ZFS too. Additional adding PNP templates for the graphs.
