/var/certs/monit.pem -keyout /var/certs/monit.pem
# openssl gendh 512 >> /var/certs/monit.pem
# openssl x509 -subject -dates -fingerprint -noout -in /var/certs/monit.pem
# chmod 700 /var/certs/monit.pem

# To change the intervals which monit should run uncomment
# and change this variable.
CHECK_INTERVALS=60

# /etc/init.d/monit start
