 +    * Change to cater for memstat/mdb changes in Solaris 11.2. \\ Some of the updates look great, but having 2 ZFS values (one for ZFS Metadata and the other for ZFS File Data) although useful, broke graphing. It's fixed now.\\ Also, please, can anybody tell me what the memstat value for "**Guest**" is? I suspect it's a memstat bug.\\ The same for the "In temporary use" that we see sometimes.\\ Yes, I am talking about the output of  ''echo "::memstat" | mdb -k'' on Solaris 11.2.
