Hi
It's long time when I have last manage AIX so this comes from my memory as I cannot check it in any AIX boxes.
you can use UF on AIX as any other *nix OS. There are some different way how you should configure it to run at boot, but there are instructions on installation guide (at least on enterprise, cannot recall if it is also on UF guide or not?).
If I recall right wtmp log is binary? If so you must use some script to convert it to text first (or was this converted to some another log daily base?). Another way is use some splunk command to read it and then use that output for UF's input.
You probably need to add some read access to splunk user as those files/commands are not available for normal users.
