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.
