Hi Frederik,

> 'lustre-info.pl --monitor=io-size' seems to sit at "collecting data, 

`io-size' reads its data from the 'disk I/O size' part of brw_stats:

>                           read      |     write
> disk I/O size          ios   % cum % |  ios   % cum %

..and in your case there are no stats, (for reasons unknown to me...)
that's why lustre-info.pl cannot display anything.

Otherwise the file looks fine: eg. `--monitor=io-time' should work.

Regards,
 Adrian
