This plugin is improved from Solaris io_busy_, io_ops_, io_bytes_ plugins.
Any device found in /usr/bin/kstat can be monitored. Any device found in /usr/bin/kstat can be monitored.
Tested with Solaris 10 and 11, and it should work with Solaris 8, 9. Tested with Solaris 10 and 11, and it should work with Solaris 8, 9.
