Linux and UNIX systems: S-TAP logs

The UNIX S-TAP has a few log files.

• guard_stap* logs, located in the filepath specified by tap_log_dir parameter.
  • guard_stap.stderr.txt: is all the output (and the extra debugging output) of STAP
  • guard_stap.fam.txt: Exists only if FAM is enabled; it contains all the output (and extra debug) of FAM monitoring.
  • guard_stap.stdout.txt. Since v10.1.4, it is present in the system, but not used.
• UNIX system log (/var/adm/syslog, /var/log/messages, name and location as relevant on the particular system): contains K-TAP module output messages (along with output messages from all other kernel tasks).
