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

41# Definitions for monitoring a router/switch
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

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

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

90# This is an optional resource file that contains $USERx$ macro
91# definitions. Multiple resource files can be specified by using
92# multiple resource_file definitions. The CGIs will not attempt to
93# read the contents of resource files, so information that is
94# considered to be sensitive (usernames, passwords, etc) can be

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

237# either in dlopen(), the kernel, and/or the filesystem. And maybe Nagios...
238#
239# The correct/safe way of updating a module is by using one of these methods:
240# 1. Shutdown Nagios, replace the module file, restart Nagios
241# 2. Delete the original module file, move the new module file into place, restart Nagios

1190# REGULAR EXPRESSION MATCHING
1191# This option controls whether or not regular expression matching
1192# takes place in the object config files. Regular expression
1193# matching is used to match host, hostgroup, service, and service
1194# group names/descriptions in some fields of various object types.

1202# This option controls whether or not "true" regular expression
1203# matching takes place in the object config files. This option
1204# only has an effect if regular expression matching is enabled
1205# (see above). If this option is DISABLED, regular expression
1206# matching only occurs if a string contains wildcard characters
1207# (* and ?). If the option is ENABLED, regexp matching occurs
1208# all the time (which can be annoying).

1226# DAEMON CORE DUMP OPTION
1227# This option determines whether or not Nagios is allowed to create
1228# a core dump when it runs as a daemon. Note that it is generally
1229# considered bad form to allow this, but it may be useful for
1230# debugging purposes. Enabling this option doesn't guarantee that
1231# a core file will be produced, but that's just life...

1243# of enabling this option.

1251# ENABLE ENVIRONMENT MACROS
1252# This option determines whether or not Nagios will make all standard
1253# macros available as environment variables when host/service checks
1254# and system commands (event handlers, notifications, etc.) are
1255# executed. Enabling this option can cause performance issues in
1256# large installations, as it will consume a bit more memory and (more
1257# importantly) consume more CPU.

1265# CHILD PROCESS MEMORY OPTION
1266# This option determines whether or not Nagios will free memory in
1267# child processes (processed used to execute system commands and host/
1268# service checks). If you specify a value here, it will override
1269# program defaults.

1277# CHILD PROCESS FORKING BEHAVIOR
1278# This option determines how Nagios will fork child processes
1279# (used to execute system commands and host/service checks). Normally
1280# child processes are fork()ed twice, which provides a very high level
1281# of isolation from problems. Fork()ing once is probably enough and will
1282# save a great deal on CPU usage (in large installs), so you might
1283# want to consider using this. If you specify a value here, it will
1284# program defaults.

1334# This option determines the maximum size (in bytes) of the debug file. If
1335# the file grows larger than this size, it will be renamed with a .old
1336# extension. If a file already exists with a .old extension it will
1337# automatically be deleted. This helps ensure your disk space usage doesn't
