Hopefully an easy one but does DA restart downed services and if so which ones? Installed SIM (System Integrity Monitor) and not sure I in fact need it!
As jackc said, DA already does that, initially just for a few services but you can modify it at will.
Just open /usr/local/directadmin/data/admin/services.status and see for yourself. http://www.directadmin.com/features.php?id=487
