perf python scripting: Improve the syscalls-by-pid script
. Print message at script start telling how to get te summary
. Print the syscall names
. Accept both pid (if numeric) or COMM name
Now it looks like this:
[root@emilia tmp]# perf trace syscall-counts-by-pid
Press control+C to stop and show the summary
^C
syscall events by comm/pid:
comm [pid]/syscalls count
