Dear all, I am running perf stat to collect the performance statistics of the already running KVM guest VM process. And I have a shell script to execute the perf stat as a daemon process. But when I use the 'kill' command to stop the perf stat, there is no output redirected to a file. What I would like to do is that to collect performance counters of the guest VM process for a certain period and redirect the output to a log file, but without user interaction (such as using CTRL + C to stop the perf stat) [root@dell06 ~]# (perf stat -p 7473 -x ,) 2> perftest & [1] 15086 [root@dell06 ~]# kill 15086 [root@dell06 ~]# [1]+ Terminated ( perf stat -p 7473 -x , ) 2> perftest [root@dell06 ~]# cat perftest [root@dell06 ~]# Any clue?
