Support for ZFS, mirror, RAIDZ2, etc.

Hello all !  New to the list.  Is there a way for gkrellm (perhaps via
plugin) to monitor the I/O or health of a zpool ?  In my searches I have
not seen a way.

I am using gkrellm 2.3.5 on Ubuntu 13.10 and 'ZFS on Linux'.  I can monitor
the individual /devs with the default install, but nothing like a
grouped-chart or health meter.

Any help would be appreciated.

Thanks,
Bryant
