autrace
AUTRACE:(8) System Administration Utilities AUTRACE:(8)
NAME
autrace - a program similar to strace
SYNOPSIS
autrace program [-r] [program-args]...
DESCRIPTION
autrace is a program that will add the audit rules to trace a process similar to strace. It will then execute the program passing arguments
to it. The resulting audit information will be in the audit logs if the audit daemon is running or syslog. This command deletes all audit
rules prior to executing the target program and after executing it. As a safety precaution, it will not run unless all rules are deleted
with auditctl prior to use.
OPTIONS
-r Limit syscalls collected to ones needed for analyzing resource usage. This could help people doing threat modeling. This saves space
in logs.
EXAMPLES
The following illustrates a typical session:
autrace /bin/ls /tmp
ausearch --start recent -p 2442 -i
and for resource usage mode:
autrace -r /bin/ls
ausearch --start recent -p 2450 --raw | aureport --file --summary
ausearch --start recent -p 2450 --raw | aureport --host --summary
SEE ALSO
ausearch(8), auditctl(8).
