Can monit be instructed to run the config file as a specified user?

You can use the "include" statement:

        include /usr/local/monit.d/*

If you'll split the configuration for the deployed processes to one file per process, you'll be to add/remove these include files automatically. You can also add check for the "include" directory timestamp ... each time you add/remove file from the directory, its mtime is updated, which you can use to reload monit automatically:

        check directory monit_includes with path /usr/local/monit.d/
                if changed timestamp then exec "/sbin/restart monit"

Note that if you'll have syntax error in new include file, monit restart attempt will kill it, as it will hit the syntax error => in the above exec action it'll be safer to use some simple script which will restart monit conditionally - check the syntax first (using "monit -t") and restart only if there are no problems, otherwise keep running and/or fire alarm.

When an app is removed I would like monit to notice this and kill the processes started by that app (this is probably too much to ask).
