RE: Monitor IO while fio is running

You might add --eta=always and --eta-newline=1 to get the current IOPs rate every 1s, printed to stdout.  You can parse that current IOPs rate via a script and do something.  I believe the IOPs rate is recalculated every 1s, not the average from beginning of test.

Not sure why --eta and --eta-newline is not in the latest HOWTO notes.

Subject: Monitor IO while fio is running

I may just not know how to do this
I know about the ability to touch /tmp/fio-dump-status which will dump the output of fio to a file or stdout while the test is running.  What I am looking for is to be able to dump the write_iops_log while fio is running so that I can see the point in time average IOps for a given interval For example if I have log_avg_msec=60000 it will write an iops.log file with 60second intervals, unfortunately this file doesn't get created until fio exits.  Is there a way to get this to dump on a regular basis (or by touching a file in /tmp) so that I can tail the output?

I am looking for a way to get point in time status via a script and the output from tmp-dump-status only gives me averages from the start of time rather than the last interval

Thank you,
Kurt
