Hi all.
I want to save the output of perf stat as a file, however, I 've tried
several ways, none of them works. Here is what I have tried.
My basic command is " timeout -s SIGINT 4s perf stat -p 32098". That
is using perf stat to capture process 32098 for 4 seconds.
perf stat -o <stat-output-file> -p 32098
Also, instead of timeout ... you can run:
perf sat -o /tmp/perfstat.out -p 32098 -- sleep 4
That tells perf to profile process 32098 and do so for as long as the
workload is running where the workload is to sleep for 4 seconds.
