This rule translates to:

auditctl -a always,exit -F dir=/testdir/checkdir -F perm=rwxa -k missingfiles

This watches any *files* in the /testdir/checkdir directory and it's 
subdirectories. To check the directory itself, you need to use the "path" 
field to point at the directory and not the files it contains.

[root ~]# mkdir temp
[root ~]# auditctl -a exit,always -F path=/root/temp -F perm=wa -k rm
[root ~]# rmdir temp/
[root ~]# ausearch --start recent -k rm
