Examples of opensnoop-nd.stp, the Linux SystemTap version.
This shows the files opened by an "iostat -x 1" command, using opensnoop-nd.stp:
# ./opensnoop-nd.stp
UID PID COMM FD PATH
0 13858 iostat 3 /etc/ld.so.cache
0 13858 iostat 3 /lib64/libc.so.6
0 13858 iostat 3 /usr/lib/locale/locale-archive
0 13858 iostat 3 /sys/devices/system/cpu
0 13858 iostat 3 /proc/diskstats
0 13858 iostat 3 /etc/localtime
0 13858 iostat 3 /proc/uptime
0 13858 iostat 3 /proc/stat
0 13858 iostat 3 /proc/diskstats
0 13858 iostat 4 /etc/sysconfig/sysstat.ioconf
0 13858 iostat 3 /proc/uptime
0 13858 iostat 3 /proc/stat
0 13858 iostat 3 /proc/diskstats
[...]
This can be a handy way to locate configuration files and source files. The
output includes /proc pathnames where the iostat statistics are sourced, as
well as /etc/sysconfig/sysstat.ioconf, a configuration file.
