Well, the funny thing is I am already using per service config files that are
shared... my monitrc just looks like this:

set logfile = syslog
set alert address@hidden
set httpd port 2812 and use address localhost
        allow localhost
        allow monit:monit
include /etc/monit/monit.d/*

and then monit.d contains files like this:

/etc/monit/monit.d/ssh:
check ssh.sshd with pidfile /var/run/sshd.pid
        start program "/etc/init.d/ssh start"
        stop program "/etc/init.d/ssh stop"
        if failed port 22 protocol ssh then restart
        if 5 restarts within 5 cycles then timeout

check file ssh.etc.ssh.sshd_config with path /etc/ssh/sshd_config
        if timestamp changed then
                exec "/etc/init.d/ssh reload"

check file ssh.usr.sbin.sshd with path /usr/sbin/sshd
        if timestamp changed then
                exec "/etc/init.d/ssh restart"

Okay.  So, what do folks think about this solution:

A script parses the monit config fragements looking for pidfile statements.
For each pidfile, check if it exists and is running.  If true, symlink from
monit.enabled/servicename -> monit.d/servicename.

Then, change the include to be

include /etc/monit/monit.enabled/*

Can anyone see a major problem with that approach?
