Gotcha.  Would a simple shell script be sufficient?  Something like:

-------------------------------
while :            ## loop forever
do
  /sbin/service [app] status
  if [$? -ne 0 ];  ## services which should be running, but are dead
                   ## return a non-zero status code
  then
    service [app] restart
  fi
  sleep 120        ## sleep for about two minutes
do
-------------------------------

Adding mail notifications and other standard functions would be trivial.  To
monitor various services just create add a for loop in there.

Just a thought.
