regex once again for PROC hobbit-client.conf

Hi !

Sorry to bother you again, with regular expression-questions :-(

I want to count and track the processes on my lustreserver

e.g.

.... ll_ost_io_98 ll_ost_io_123 ll_ost_io_124 . .

and

... ll_ost_87 ll_ost_123 . . ...

How can i exclude "ll_ost_io_" for counting the "ll_ost_XX" processes ...

e.g.

hobbit-client.conf

PROC ll_ost_io 0 -1 TRACK=ll_ost_io PROC "%ll_ost_[???]" 0 -1 TRACK=ll_ost

doesn't work, of course :-(

thanks in advance & cheers,

    martin
