Hi folks..
I was thinking that why cant we have a timeout option in perf stat
command. The timeout feature will help us to profile a process for a
stipulated time (preferably in millisecs) and make perf stat return
after that time.
Eg:
perf stat --timeout=10 sleep 100
This will make perf return and report stats after 10 ms...
Hope anyone can shed some more light on the idea
It seems preferable to use the timeout program to do this.
Either sending a handled signal to the perf process like:
timeout -s HUP 10 perf stat sleep 100
Or even better, just use that to kill the monitored process itself
perf stat timeout 10 sleep 100
