##
|
||||||
|
## Start Monit in the background (run as a daemon):
|
||||||
|
#
|
||||||
|
set daemon 30 # check services at 30 seconds intervals
|
||||||
|
# with start delay 240 # optional: delay the first check by 4-minutes (by
|
||||||
|
# # default Monit check immediately after Monit start)
|
||||||
|
#
|
||||||
|
#
|
||||||
|
## Set syslog logging. If you want to log to a standalone log file instead,
|
||||||
|
## specify the full path to the log file
|
||||||
|
#
|
||||||
|
set log syslog
|
||||||
|
|
||||||
|
#
|
||||||
|
#
|
||||||
|
## Set the location of the Monit lock file which stores the process id of the
|
||||||
|
## running Monit instance. By default this file is stored in $HOME/.monit.pid
|
||||||
|
#
|
||||||
|
# set pidfile /var/run/monit.pid
|
||||||
|
#
|
||||||
|
## Set the location of the Monit id file which stores the unique id for the
|
||||||
|
## Monit instance. The id is generated and stored on first Monit start. By
|
||||||
|
## default the file is placed in $HOME/.monit.id.
|
||||||
|
#
|
||||||
|
# set idfile /var/.monit.id
|
||||||
|
#
|
||||||
|
## Set the location of the Monit state file which saves monitoring states
|
||||||
|
## on each cycle. By default the file is placed in $HOME/.monit.state. If
|
||||||
|
## the state file is stored on a persistent filesystem, Monit will recover
|
||||||
|
## the monitoring state across reboots. If it is on temporary filesystem, the
|
||||||
|
## state will be lost on reboot which may be convenient in some situations.
|
||||||
|
#
|
||||||
|
# set statefile /var/.monit.state
|
||||||
|
#
|
||||||
|
#
|
||||||
|
|
||||||
|
## Set limits for various tests. The following example shows the default values:
|
||||||
|
##
|
||||||
|
# set limits {
|
||||||
|
# programOutput: 512 B, # check program's output truncate limit
|
||||||
|
# sendExpectBuffer: 256 B, # limit for send/expect protocol test
|
||||||
|
# fileContentBuffer: 512 B, # limit for file content test
|
||||||
|
# httpContentBuffer: 1 MB, # limit for HTTP content test
|
||||||
|
# networkTimeout: 5 seconds # timeout for network I/O
|
||||||
|
# programTimeout: 300 seconds # timeout for check program
|
||||||
|
# stopTimeout: 30 seconds # timeout for service stop
|
||||||
|
# startTimeout: 30 seconds # timeout for service start
|
||||||
|
# restartTimeout: 30 seconds # timeout for service restart
|
||||||
|
# }
|
||||||
|
|
||||||
|
## Set global SSL options (just most common options showed, see manual for
|
||||||
|
## full list).
|
||||||
|
#
|
||||||
|
# set ssl {
|
||||||
|
# verify : enable, # verify SSL certificates (disabled by default but STRONGLY RECOMMENDED)
|
||||||
|
# selfsigned : allow # allow self signed SSL certificates (reject by default)
|
||||||
|
# }
|
||||||
|
#
|
||||||
|
#
|
||||||
|
## Set the list of mail servers for alert delivery. Multiple servers may be
|
||||||
|
## specified using a comma separator. If the first mail server fails, Monit
|
||||||
|
# will use the second mail server in the list and so on. By default Monit uses
|
||||||
|
# port 25 - it is possible to override this 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 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 queue size
|
||||||
|
## by 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 # optionally limit the queue size
|
||||||
|
#
|
||||||
|
#
|
||||||
|
## Send status and events to M/Monit (for more informations about M/Monit
|
||||||
|
## see https://mmonit.com/). By default Monit registers credentials with
|
||||||
|
## M/Monit so M/Monit can smoothly communicate back to Monit and you don't
|
||||||
|
## have to register Monit credentials manually in M/Monit. It is possible to
|
||||||
|
## disable credential registration using the commented out option below.
|
||||||
|
## Though, if safety is a concern we recommend instead using https when
|
||||||
|
## communicating with M/Monit and send credentials encrypted. The password
|
||||||
|
## should be URL encoded if it contains URL-significant characters like
|
||||||
|
## ":", "?", "@". Default timeout is 5 seconds, you can customize it by
|
||||||
|
## adding the timeout option.
|
||||||
|
#
|
||||||
|
# set mmonit http://monit:monit@192.168.1.10:8080/collector
|
||||||
|
# # with timeout 30 seconds # Default timeout is 5 seconds
|
||||||
|
# # and register without credentials # Don't register credentials
|
||||||
|
#
|
||||||
|
#
|
||||||
|
## Monit by default uses the following format for alerts if the mail-format
|
||||||
|
## statement is missing::
|
||||||
|
## --8<--
|
||||||
|
## set mail-format {
|
||||||
|
## from: Monit <monit@$HOST>
|
||||||
|
## subject: monit alert -- $EVENT $SERVICE
|
||||||
|
## message: $EVENT Service $SERVICE
|
||||||
|
## Date: $DATE
|
||||||
|
## Action: $ACTION
|
||||||
|
## Host: $HOST
|
||||||
|
## 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, use:
|
||||||
|
#
|
||||||
|
# set mail-format { from: monit@foo.bar }
|
||||||
|
#
|
||||||
|
#
|
||||||
|
## You can set alert recipients 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
|
||||||
|
#
|
||||||
|
## Do not alert when Monit starts, stops or performs a user initiated action.
|
||||||
|
## This filter is recommended to avoid getting alerts for trivial cases.
|
||||||
|
#
|
||||||
|
# set alert your-name@your.domain not on { instance, action }
|
||||||
|
#
|
||||||
|
#
|
||||||
|
## Monit has an embedded HTTP interface which can be used to view status of
|
||||||
|
## services monitored and manage services from a web interface. The HTTP
|
||||||
|
## interface is also required if you want to issue Monit commands from the
|
||||||
|
## command line, such as 'monit status' or 'monit restart service' The reason
|
||||||
|
## for this is that the Monit client uses the HTTP interface to send these
|
||||||
|
## commands to a running Monit daemon. See the Monit Wiki if you want to
|
||||||
|
## enable SSL for the HTTP 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'
|
||||||
|
#with ssl { # enable SSL/TLS and set path to server certificate
|
||||||
|
# pemfile: /etc/ssl/certs/monit.pem
|
||||||
|
#}

##
|
||||||
|
## 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 $HOST
|
||||||
|
# if loadavg (1min) > 4 then alert
|
||||||
|
# if loadavg (5min) > 2 then alert
|
||||||
|
# if cpu usage > 95% for 10 cycles then alert
|
||||||
|
# if memory usage > 75% then alert
|
||||||
|
# if swap usage > 25% then alert
|
||||||
|
#
|
||||||
|
#
|
||||||
|
## Check if a file exists, checksum, permissions, uid and gid. In addition
|
||||||
|
## to alert recipients in the global section, customized alert can be sent to
|
||||||
|
## additional recipients by specifying a local alert handler. The service may
|
||||||
|
## be grouped using the GROUP option. More than one group can be specified by
|
||||||
|
## repeating the 'group name' statement.
|
||||||
|
#
|
||||||
|
# check file apache_bin with path /usr/local/apache/bin/httpd
|
||||||
|
# if failed checksum and
|

## 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 is 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

|
||||||
|
#
|
||||||
|
## 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 a remote host availability by issuing a ping test and check the
|
||||||
|
## content of a response from a web server. Up to three pings are sent and
|
||||||
|
## connection to a port and an application level network check is performed.
|
||||||
|
#
|
||||||
|
# check host myserver with address 192.168.1.1

## Check a network link status (up/down), link capacity changes, saturation
|
||||||
|
## and bandwidth usage.
|
||||||
|
#
|
||||||
|
# check network public with interface eth0

## Check custom program status output.
|

|
#
|
||||||
|
# check program myscript with path /usr/local/bin/myscript.sh
