Monit should not manage critical memory disks, since unmounting renders the
system unusable.

16##
17## Start Monit in the background (run as a daemon):
18#
19set daemon 60 # check services at 60 seconds intervals
20 with start delay 120 # optional: delay the first check by 2-minutes (by
21# # default Monit check immediately after Monit start)
22#
23#
24## Set syslog logging. If you want to log to a standalone log file instead,
25## specify the full path to the log file
26#
27set logfile syslog
28
29#
30#
31## Set the location of the Monit lock file which stores the process id of the
32## running Monit instance. By default this file is stored in $HOME/.monit.pid
33#
34 set pidfile /var/run/monit.pid
35#
36## Set the location of the Monit id file which stores the unique id for the
37## Monit instance. The id is generated and stored on first Monit start. By
38## default the file is placed in $HOME/.monit.id.
39#
40 set idfile /var/.monit.id
41#
42## Set the location of the Monit state file which saves monitoring states
43## on each cycle. By default the file is placed in $HOME/.monit.state. If
44## the state file is stored on a persistent filesystem, Monit will recover
45## the monitoring state across reboots. If it is on temporary filesystem, the
46## state will be lost on reboot which may be convenient in some situations.
47#
48 set statefile /var/.monit.state
49#
50#
51
52## Set limits for various tests. The following example shows the default values:
53##
54# set limits {
55# programOutput: 512 B, # check program's output truncate limit
56# sendExpectBuffer: 256 B, # limit for send/expect protocol test
57# fileContentBuffer: 512 B, # limit for file content test
58# httpContentBuffer: 1 MB, # limit for HTTP content test
59# networkTimeout: 5 seconds # timeout for network I/O
60# programTimeout: 300 seconds # timeout for check program
61# stopTimeout: 30 seconds # timeout for service stop
62# startTimeout: 30 seconds # timeout for service start
63# restartTimeout: 30 seconds # timeout for service restart
64# }
65
66## Set global SSL options (just most common options showed, see manual for
67## full list).
68#
69# set ssl {
70# verify : enable, # verify SSL certificates (disabled by default but STRONGLY RECOMMENDED)
71# selfsigned : allow # allow self signed SSL certificates (reject by default)
72# }
73#
74#
75## Set the list of mail servers for alert delivery. Multiple servers may be
76## specified using a comma separator. If the first mail server fails, Monit
77# will use the second mail server in the list and so on. By default Monit uses
78# port 25 - it is possible to override this with the PORT option.
79#
80# set mailserver mail.bar.baz, # primary mailserver
81# backup.bar.baz port 10025, # backup mailserver on port 10025
82# localhost # fallback relay
83#
84#
85## By default Monit will drop alert events if no mail servers are available.
86## If you want to keep the alerts for later delivery retry, you can use the
87## EVENTQUEUE statement. The base directory where undelivered alerts will be
88## stored is specified by the BASEDIR option. You can limit the queue size
89## by using the SLOTS option (if omitted, the queue is limited by space
90## available in the back end filesystem).
91#
92 set eventqueue
93 basedir /var/monit # set the base directory where events will be stored
94 slots 100 # optionally limit the queue size
95#
96#
97## Send status and events to M/Monit (for more informations about M/Monit
98## see https://mmonit.com/). By default Monit registers credentials with
99## M/Monit so M/Monit can smoothly communicate back to Monit and you don't
100## have to register Monit credentials manually in M/Monit. It is possible to
101## disable credential registration using the commented out option below.
102## Though, if safety is a concern we recommend instead using https when
103## communicating with M/Monit and send credentials encrypted. The password
104## should be URL encoded if it contains URL-significant characters like
105## ":", "?", "@".
106#
107# set mmonit http://monit:monit@192.168.1.10:8080/collector
108# # and register without credentials # Don't register credentials
109#
110#
111## Monit by default uses the following format for alerts if the the mail-format
112## statement is missing::
113## --8<--
114## set mail-format {
115## from: Monit <monit@$HOST>
116## subject: monit alert -- $EVENT $SERVICE
117## message: $EVENT Service $SERVICE
118## Date: $DATE
119## Action: $ACTION
120## Host: $HOST
121## Description: $DESCRIPTION
122##
123## Your faithful employee,
124## Monit
125## }
126## --8<--
127##
128## You can override this message format or parts of it, such as subject
129## or sender using the MAIL-FORMAT statement. Macros such as $DATE, etc.
130## are expanded at runtime. For example, to override the sender, use:
131#
132# set mail-format { from: monit@foo.bar }
133#
134#
135## You can set alert recipients whom will receive alerts if/when a
136## service defined in this file has errors. Alerts may be restricted on
137## events by using a filter as in the second example below.
138#
139# set alert sysadm@foo.bar # receive all alerts
140#
141## Do not alert when Monit starts, stops or performs a user initiated action.
142## This filter is recommended to avoid getting alerts for trivial cases.
143#
144# set alert your-name@your.domain not on { instance, action }
145#
146#
147## Monit has an embedded HTTP interface which can be used to view status of
148## services monitored and manage services from a web interface. The HTTP
149## interface is also required if you want to issue Monit commands from the
150## command line, such as 'monit status' or 'monit restart service' The reason
151## for this is that the Monit client uses the HTTP interface to send these
152## commands to a running Monit daemon. See the Monit Wiki if you want to
153## enable SSL for the HTTP interface.
154#
155set httpd port 2812 and
156# use address localhost # only accept connection from localhost
157 allow 172.16.0.0/12
158 allow localhost
159# allow localhost # allow localhost to connect to the server and
160# allow guest:guest read-only
