+## Monit control file
+###############################################################################
+##
+## Comments begin with a '#' and extend through the end of the line. Keywords
+## are case insensitive. All path's MUST BE FULLY QUALIFIED, starting with '/'.
+##
+## Below you will find examples of some frequently used statements. For 
+## information about the control file, a complete list of statements and 
+## options please have a look in the monit manual.
+##
+##
+###############################################################################
+## Global section
+###############################################################################
+##
+## Start monit in the background (run as a daemon) and check services at 
+## 2-minute intervals.
+#
+# set daemon  120
+#
+#
+## Set syslog logging with the 'daemon' facility. If the FACILITY option is
+## omitted, monit will use 'user' facility by default. If you want to log to 
+## a stand alone log file instead, specify the path to a log file
+#
+# set logfile syslog facility log_daemon                       
+#
+#
+## Set the list of mail servers for alert delivery. Multiple servers may be 
+## specified using comma separator. By default monit uses port 25 - this
+## is possible to override with the PORT option.
+#
+# set mailserver mail.bar.baz,               # primary mailserver
+#                backup.bar.baz port 10025,  # backup mailserver on port 10025
+#                localhost                   # fallback relay
+#
+#
+## By default monit will drop alert events if no mail servers are available. 
+## If you want to keep the alerts for a later delivery retry, you can use the 
+## EVENTQUEUE statement. The base directory where undelivered alerts will be 
+## stored is specified by the BASEDIR option. You can limit the maximal queue
+## size using the SLOTS option (if omitted, the queue is limited by space 
+## available in the back end filesystem).
+#
+# set eventqueue
+#     basedir /var/monit  # set the base directory where events will be stored
+#     slots 100           # optionaly limit the queue size
+#
+#
+## Monit by default uses the following alert mail format:
+##
+## --8<--
+## From: monit@$HOST                         # sender
+## Subject: monit alert --  $EVENT $SERVICE  # subject
+##
+## $EVENT Service $SERVICE                   #
+##                                           #
+##      Date:        $DATE                   #
+##      Action:      $ACTION                 #
+##      Host:        $HOST                   # body
+##      Description: $DESCRIPTION            #
+##                                           #
+## Your faithful employee,                   #
+## monit                                     #
+## --8<--
+##
+## You can override this message format or parts of it, such as subject
+## or sender using the MAIL-FORMAT statement. Macros such as $DATE, etc.
+## are expanded at runtime. For example, to override the sender:
+#
+# set mail-format { from: monit@foo.bar }
+#
+#
+## You can set alert recipients here whom will receive alerts if/when a 
+## service defined in this file has errors. Alerts may be restricted on 
+## events by using a filter as in the second example below. 
+#
+# set alert sysadm@foo.bar                       # receive all alerts
+# set alert manager@foo.bar only on { timeout }  # receive just service-
+#                                                # timeout alert
+#
+#
+## Monit has an embedded web server which can be used to view status of 
+## services monitored, the current configuration, actual services parameters
+## and manage services from a web interface.
+#
+# set httpd port 2812 and
+#     use address localhost  # only accept connection from localhost
+#     allow localhost        # allow localhost to connect to the server and
+#     allow admin:monit      # require user 'admin' with password 'monit'
+#

+## Services
+###############################################################################
+##
+## Check general system resources such as load average, cpu and memory
+## usage. Each test specifies a resource, conditions and the action to be
+## performed should a test fail.
+#
+#  check system myhost.mydomain.tld
+#    if loadavg (1min) > 4 then alert
+#    if loadavg (5min) > 2 then alert
+#    if memory usage > 75% then alert
+#    if cpu usage (user) > 70% then alert
+#    if cpu usage (system) > 30% then alert
+#    if cpu usage (wait) > 20% then alert
+#
+#    
+## Check a file for existence, checksum, permissions, uid and gid. In addition
+## to alert recipients in the global section, customized alert will be sent to 
+## additional recipients by specifying a local alert handler. The service may 
+## be grouped using the GROUP option.
+#    
+#  check file apache_bin with path /usr/local/apache/bin/httpd
+#    if failed checksum and 
+#       expect the sum 8f7f419955cefa0b33a2ba316cba3659 then unmonitor
+#    if failed permission 755 then unmonitor
+#    if failed uid root then unmonitor
+#    if failed gid root then unmonitor
+#    alert security@foo.bar on {
+#           checksum, permission, uid, gid, unmonitor
+#        } with the mail-format { subject: Alarm! }
+#    group server
+#
+#    
+## Check that a process is running, in this case Apache, and that it respond
+## to HTTP and HTTPS requests. Check its resource usage such as cpu and memory,
+## and number of children. If the process is not running, monit will restart 
+## it by default. In case the service was restarted very often and the 
+## problem remains, it is possible to disable monitoring using the TIMEOUT
+## statement. This service depends on another service (apache_bin) which
+## is defined above.
+#    
+#  check process apache with pidfile /usr/local/apache/logs/httpd.pid
+#    start program = "/etc/init.d/httpd start"
+#    stop program  = "/etc/init.d/httpd stop"
+#    if cpu > 60% for 2 cycles then alert

+#    if totalmem > 200.0 MB for 5 cycles then restart
+#    if children > 250 then restart
+#    if loadavg(5min) greater than 10 for 8 cycles then stop
+#    if failed host www.tildeslash.com port 80 protocol http
+#       and request "/monit/doc/next.php"

+#       with timeout 15 seconds
+#       then restart
+#    if 3 restarts within 5 cycles then timeout
+#    depends on apache_bin
+#    group server
+#    
+#    
+## Check device permissions, uid, gid, space and inode usage. Other services,
+## such as databases, may depend on this resource and an automatically graceful
+## stop may be cascaded to them before the filesystem will become full and data
+## lost.
+#
+#  check device datafs with path /dev/sdb1
+#    start program  = "/bin/mount /data"
+#    stop program  = "/bin/umount /data"
+#    if failed permission 660 then unmonitor
+#    if failed uid root then unmonitor
+#    if failed gid disk then unmonitor
+#    if space usage > 80% for 5 times within 15 cycles then alert
+#    if space usage > 99% then stop
+#    if inode usage > 30000 then alert
+#    if inode usage > 99% then stop
+#    group server
+#
+#
+## Check a file's timestamp. In this example, we test if a file is older 
+## than 15 minutes and assume something is wrong if its not updated. Also,
+## if the file size exceed a given limit, execute a script
+#
+#  check file database with path /data/mydatabase.db
+#    if failed permission 700 then alert
+#    if failed uid data then alert
+#    if failed gid data then alert
+#    if timestamp > 15 minutes then alert
+#    if size > 100 MB then exec "/my/cleanup/script"
+#
+#
+## Check directory permission, uid and gid.  An event is triggered if the 
+## directory does not belong to the user with uid 0 and gid 0.  In addition, 
+## the permissions have to match the octal description of 755 (see chmod(1)).
+#
+#  check directory bin with path /bin
+#    if failed permission 755 then unmonitor
+#    if failed uid 0 then unmonitor
+#    if failed gid 0 then unmonitor
+#
+#
+## Check a remote host network services availability using a ping test and 
+## check response content from a web server. Up to three pings are sent and 
+## connection to a port and a application level network check is performed.
+#
+#  check host myserver with address 192.168.1.1
+#    if failed icmp type echo count 3 with timeout 3 seconds then alert
+#    if failed port 3306 protocol mysql with timeout 15 seconds then alert
+#    if failed url
+#       http://user:password@www.foo.bar:8080/?querystring
+#       and content == 'action="j_security_check"'
+#       then alert
