15# This is the main log file where service and host events are logged

23# OBJECT CONFIGURATION FILE(S)
24# These are the object configuration files in which you define hosts,
25# host groups, contacts, contact groups, services, etc.
26# You can split your object definitions across several config files
27# if you wish (as shown below), or keep them all in a single config file.
28
29# You can specify individual object config files as shown below:
30cfg_file=/usr/local/etc/nagios/objects/commands.cfg
31cfg_file=/usr/local/etc/nagios/objects/contacts.cfg
32cfg_file=/usr/local/etc/nagios/objects/timeperiods.cfg
33cfg_file=/usr/local/etc/nagios/objects/templates.cfg

35# Definitions for monitoring the local (FreeBSD) host
36# cfg_file=/usr/local/etc/nagios/objects/localhost.cfg

38# Definitions for monitoring a Windows machine
39#cfg_file=/usr/local/etc/nagios/objects/windows.cfg

42#cfg_file=/usr/local/etc/nagios/objects/switch.cfg
43
44# Definitions for monitoring a network printer
45#cfg_file=/usr/local/etc/nagios/objects/printer.cfg
46
47
48# You can also tell Nagios to process all config files (with a .cfg
49# extension) in a particular directory by using the cfg_dir
50# directive as shown below:
51
52#cfg_dir=/usr/local/etc/nagios/servers
53#cfg_dir=/usr/local/etc/nagios/printers
54#cfg_dir=/usr/local/etc/nagios/switches

63# OBJECT CACHE FILE
64# This option determines where object definitions are cached when
65# Nagios starts/restarts. The CGIs read object definitions from
66# this cache file (rather than looking at the object config files
67# directly) in order to prevent inconsistencies that can occur
68# when the config files are modified after Nagios starts.

71
72
73
74# PRE-CACHED OBJECT FILE
75# This options determines the location of the precached object file.
76# If you run Nagios with the -p command line option, it will preprocess
77# your object configuration file(s) and write the cached config to this
78# file. You can then start Nagios with the -u option to have it read
79# object definitions from this precached file, rather than the standard
80# object configuration files (see the cfg_file and cfg_dir options above).
81# Using a precached object file can speed up the time needed to (re)start
82# the Nagios process if you've got a large and/or complex configuration.
83# Read the documentation section on optimizing Nagios to find our more
84# about how this feature works.

92# definitions. Multiple resource files can be specified by using
93# multiple resource_file definitions. The CGIs will not attempt to
94# read the contents of resource files, so information that is
95# considered to be sensitive (usernames, passwords, etc) can be

153# that at its default value of 60 (seconds), a value of 1 here will cause
154# Nagios to check for external commands every minute. If you specify a
155# number followed by an "s" (i.e. 15s), this will be interpreted to mean
156# actual seconds rather than a multiple of the interval_length variable.
157# Note: In addition to reading the external command file at regularly
158# scheduled intervals, Nagios will also check for external commands after
159# event handlers are executed.

236# Do NOT overwrite modules while they are being used by Nagios or Nagios

240# The correct/safe way of updating a module is by using one of these methods:
241# 1. Shutdown Nagios, replace the module file, restart Nagios
242# 2. Delete the original module file, move the new module file into place, restart Nagios

1191# REGULAR EXPRESSION MATCHING
1192# This option controls whether or not regular expression matching
1193# takes place in the object config files. Regular expression
1194# matching is used to match host, hostgroup, service, and service
1195# group names/descriptions in some fields of various object types.

1205# only has an effect if regular expression matching is enabled
1206# (see above). If this option is DISABLED, regular expression
1207# matching only occurs if a string contains wildcard characters
1208# (* and ?). If the option is ENABLED, regexp matching occurs
1209# all the time (which can be annoying).

1228# This option determines whether or not Nagios is allowed to create
1229# a core dump when it runs as a daemon. Note that it is generally
1230# considered bad form to allow this, but it may be useful for
1231# debugging purposes. Enabling this option doesn't guarantee that
1232# a core file will be produced, but that's just life...

1254# macros available as environment variables when host/service checks
1255# and system commands (event handlers, notifications, etc.) are
1256# executed. Enabling this option can cause performance issues in
1257# large installations, as it will consume a bit more memory and (more
1258# importantly) consume more CPU.

1278# CHILD PROCESS FORKING BEHAVIOR
1279# This option determines how Nagios will fork child processes
1280# (used to execute system commands and host/service checks). Normally
1281# child processes are fork()ed twice, which provides a very high level
1282# of isolation from problems. Fork()ing once is probably enough and will
1283# save a great deal on CPU usage (in large installs), so you might
1284# want to consider using this. If you specify a value here, it will
1285# program defaults.
