  httpd_address  => '172.16.0.3',
  httpd_password => 'CHANGE_ME',
}

Add a check

Using the source parameter:

monit::check { 'ntp':
  source => "puppet:///modules/${module_name}/ntp",
}

Or using the content parameter with a string:

monit::check { 'ntp':
  content => 'check process ntpd with pidfile /var/run/ntpd.pid
  start program = "/etc/init.d/ntpd start"
  stop  program = "/etc/init.d/ntpd stop"
  if failed host 127.0.0.1 port 123 type udp then alert
  if 5 restarts within 5 cycles then timeout
',
}

Or using the content parameter with a template:

monit::check { 'ntp':
  content => template("${module_name}/ntp.erb"),
