I'm looking at running some scheduled actions, and can't find any
mention of a log of what was successful and what failed.

Basically I want to WOL, install some software, and shutdown. I then
want to know that machines A, B, and C worked, and D, E, and F didn't
so I can deal with the failures manually.

Is there a log? Where is it?
If there isn't a log, and ideas how to know about success/failure?
