Here is the verbose output. Looks like verbose output begins and ends at
process start up (host/domain names changed):

Starting Process Monitor (monit): monit: Debug: Adding host allow
monit: Debug: Skipping redundant host 'localhost'
monit: Debug: Skipping redundant host 'localhost'
monit: Debug: Adding credentials for user 'admin'.
Runtime constants:
 Control file       = /etc/monit.conf
 Log file           = syslog
 Pid file           = /var/run/
 Debug              = True
 Log                = True
 Use syslog         = True
 Is Daemon          = True
 Use process engine = True
 Poll time          = 60 seconds
 Mail server(s)     =
 Mail from          = address@hidden
 Mail subject       = monit alert --  $EVENT $SERVICE
 Mail message       = $EVENT Service $SERV..(truncated)
 Start monit httpd  = True
 httpd bind address = localhost
 httpd portnumber   = 2812
 httpd signature    = True
 Use ssl encryption = False
 httpd auth. style  = Basic Authentication and Host/Net allow list
 Alert mail to      = address@hidden
   Alert on         = All events

The service list contains the following entries:

Process Name          = ntpd
 Pid file             = /var/run/
 Monitoring mode      = active
 Start program        = '/etc/init.d/ntpd start' timeout 1 cycle(s)
 Stop program         = '/etc/init.d/ntpd stop' timeout 1 cycle(s)
 Pid                  = if changed 1 times within 1 cycle(s) then alert
 Ppid                 = if changed 1 times within 1 cycle(s) then alert
 Timeout              = If 3 restart within 3 cycles then unmonitor else if
passed then alert

System Name           =
 Monitoring mode      = active

monit: pidfile '/var/run/' does not exist
Starting monit daemon with http interface at [localhost:2812]

Then when ntp is killed I see the following in /var/log/messages:

Jan 16 19:10:50 test-prod ntpd[13505]: ntpd exiting on signal 15
Jan 16 19:11:32 test-prod monit[2398]: 'ntpd' process is not running
Jan 16 19:11:32 test-prod monit[2398]: 'ntpd' trying to restart
Jan 16 19:11:32 test-prod monit[2398]: 'ntpd' start: /etc/init.d/ntpd
Jan 16 19:11:32 test-prod ntpd[2541]: ntpd address@hidden Tue Jun 10
00:07:18 UTC 2008 (1)
Jan 16 19:11:32 test-prod ntpd[2542]: precision = 2.000 usec

There is no additional output from monit and no attempt to send mail
according to maillog.
