Thank you Jeff for the reply.
I have been playing around with this but unfortunately I cannot get the output to be outputted anywhere other than the screen / terminal. I have tried redirecting it to a txt file and parsing with with a python script but nothing ever gets output. (It only outputs to the screen)
I haven't done C programming in years but I am trying to figure out from the code why this is. I see in the eta.c file
void display_thread_status(struct jobs_eta *je)
{
...
printf("%s", output);
if (!eta_new_line_init) {
fio_gettime(&disp_eta_new_line, NULL);
eta_new_line_init = 1;
} else if (eta_new_line && mtime_since_now(&disp_eta_new_line) > eta_new_line) {
fio_gettime(&disp_eta_new_line, NULL);
eta_new_line_pending = 1;
}
fflush(stdout);
It prints everything to the screen but I cannot redirect it at all
Thoughts?
Thank you,
Kurt

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.

Jeff

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
