You can write a script that uses ps to monitor the particular processes
you want to make sure are running.   You can use ps piped to grep to
look for the particular process you are looking for.  Test the results
and if it is not there have it notify you via email or some other means
or you can even try to restart the process in the script.

Put this script in a cron job to run periodically say every 5 minutes or
so.
