perf python scripting: Improve the failed-syscalls-by-pid script
. Print message at script start telling how to get te summary
. Print the syscall name using the audit-lib-python package, if
installed
. Print the errno string
. Accept both pid (if numeric) or COMM name
Now it looks like this:
[root@emilia ~]# perf trace failed-syscalls-by-pid
Press control+C to stop and show the summary
^C
syscall errors:
comm [pid] count
------------------------------ ----------
automount [1670]
syscall: futex
err = ETIMEDOUT 39
irqbalance [1462]
syscall: openat
err = ENOENT 4
perf [7888]
syscall: lseek
err = ESPIPE 1
syscall: open
err = ENOENT 24
perf [7889]
syscall: ioctl
err = EINVAL 1
syscall: readlink
err = EINVAL 2
syscall: open
err = ENOENT 389
syscall: stat
err = ENOENT 141
syscall: lseek
err = ESPIPE 3
