Munin contributed plugins

  These functions are implemented:

     ops     : similar to iostat r/s, w/s

     busy    : similar to iostat %b, %w (%w usually indicates 0 in Sol10,11)

     queue   : similar to iostat actv, wait

     latency : similar to iostat asvc_t, wsvc_t

    cd /path/to/munin/etc/plugins

    ln -s /path/to/munin/lib/plugins/io_disk .

  by this plugin.

  Thus, please remove symlinks of those plugins before using this plugin.

    example:  env.module  something

    default:  sd
