Try this:
1. put to /etc/monit.conf this line:
include /etc/monit.d/*.conf
2. for active services make you own files in /etc/monit.d,
ex. /etc/monit.d/sshd.conf:
# ssh control
check process sshd with pidfile /var/run/sshd.pid
start program "/etc/init.d/sshd start"
stop program "/etc/init.d/sshd stop"
if 5 restarts within 5 cycles then timeout
3. when you change service to
chkconfig sshd off
rename /etc/monit.d/sshd.conf to something different:
mv /etc/monit.d/sshd.conf /etc/monit.d/sshd.conf-dontuse
