The documentation on caitsith.sourceforge > is lacking. It depends on the event - if you look at the per-event docs[1], you'll see the variables it'll log. For instance, inet_stream_bind has 'ip', 'port', and 'task.$attribute' listed (and hyperlinked), so it'll log like this: // These fields are common across all events: // time, root-pid-ns PID, result, acl-priority, and chroot path #2012/04/08 05:03:03# global-pid=3720 result=unmatched priority=0 / // Then the action inet_stream_bind // then the variables ip=0.0.0.0 port=80 task.pid=2245 task.ppid=3422 task.uid=81 task.gid=81 task.euid=81 task.egid=81 task.suid=0 task.sgid=0 task.fsuid=81 task.fsgid=81 task.type!=execute_handler task.exe="/user/bin/httpd" task.domain="/usr/bin/httpd" [1] Start at http://caitsith.sourceforge.jp/#5.26 and scroll
