thanks. tried to contact redflag, but they don`t answer. maybe support is
being on holiday.... !?
linux kernel hackers - there is really no standard way to watch i/o metrics
(bytes read/written) at process level?
it`s extremly hard for the admin to track down, what process is hogging the
disk - especially if there is more than one task consuming cpu.
meanwhile i found blktrace and read into the documenation. looks really cool
and seems to be very powerful tool - but it it`s seems a little bit
"oversized" and not the right tool for this. seems to be for
tracing/debugging/analysis
what about http://lkml.org/lkml/2005/9/12/89 "with following patch,
userspace processes/utilities will be able to access per process I/O
statistics. for example, top like utilites can use this information" which
has been posted to lkml one year ago ? any update on this ?

is there a modified top/ps with i/o column, or is there yet missing
something at the kernel level for getting that counters from ?
Red Flag(http://www.redflag-linux.com/eindex.html) has developed an
iotop based on kprobes/systemtap. You can contact them if necessary.
