+#
+# Read the documentation for more information on this configuration
+# file.  I've provided some comments here, but things may not be so
+# clear without further explanation.
+#
+#
+##############################################################################
+
+
+# LOG FILE
+# This is the main log file where service and host events are logged
+# for historical purposes.  This should be the first option specified
+# in the config file!!!
+
+log_file=@logDir@/naemon.log
+
+
+
+# OBJECT CONFIGURATION FILE(S)
+# These are the object configuration files in which you define hosts,
+# host groups, contacts, contact groups, services, etc.
+# You can split your object definitions across several config files
+# if you wish (as shown below), or keep them all in a single config file.
+
+# You can specify individual object config files as shown below:
+#cfg_file=/etc/naemon/objects/commands.cfg
+#cfg_file=/etc/naemon/objects/contacts.cfg
+#cfg_file=/etc/naemon/objects/timeperiods.cfg
+#cfg_file=/etc/naemon/objects/templates.cfg
+cfg_file=@objectsFile@
+
+
+# You can also tell naemon to process all config files (with a .cfg
+# extension) in a particular directory by using the cfg_dir
+# directive as shown below:
+#cfg_dir=/etc/naemon/conf.d
+
+
+
+
+# OBJECT CACHE FILE
+# This option determines where object definitions are cached when
+# naemon starts/restarts.  The CGIs read object definitions from
+# this cache file (rather than looking at the object config files
+# directly) in order to prevent inconsistencies that can occur
+# when the config files are modified after naemon starts.
+
+object_cache_file=@varDir@/objects.cache
+
+
+
+# PRE-CACHED OBJECT FILE
+# This options determines the location of the precached object file.
+# If you run naemon with the -p command line option, it will preprocess
+# your object configuration file(s) and write the cached config to this
+# file.  You can then start naemon with the -u option to have it read
+# object definitions from this precached file, rather than the standard
+# object configuration files (see the cfg_file and cfg_dir options above).
+# Using a precached object file can speed up the time needed to (re)start
+# the naemon process if you've got a large and/or complex configuration.
+# Read the documentation section on optimizing naemon to find our more
+# about how this feature works.
+
+precached_object_file=@varDir@/objects.precache
+
+
+
+# RESOURCE FILE
+# This is an optional resource file that contains $USERx$ macro
+# definitions. Multiple resource files can be specified by using
+# multiple resource_file definitions.  The CGIs will not attempt to
+# read the contents of resource files, so information that is
+# considered to be sensitive (usernames, passwords, etc) can be
+# defined as macros in this file and restrictive permissions (600)
+# can be placed on this file.

+#  restarts.
+
+status_file=@varDir@/status.dat

+# This option determines the frequency (in seconds) that
+# naemon will periodically dump program, host, and
+# service status data. Set it to 0 to disable updates.
+
+status_update_interval=10
+
+
+
+# EXTERNAL COMMAND OPTION
+# This option allows you to specify whether or not Naemon should check
+# for external commands (in the command file defined below).  By default
+# Naemon will *not* check for external commands, just to be on the
+# cautious side.  If you want to be able to use the CGI command interface
+# you will have to enable this.

+
+
+
+# EXTERNAL COMMAND FILE
+# This is the file that Naemon checks for external command requests.
+# It is also where the command CGI will write commands that are submitted
+# by users, so it must be writeable by the user that the web server
+# is running as (usually 'nobody').  Permissions should be set at the
+# directory level instead of on the file, as the file is deleted every
+# time its contents are processed.
+
+command_file=@runDir@/naemon.cmd

+# EVENT BROKER OPTIONS
+# Controls what (if any) data gets sent to the event broker.

+
+
+# EVENT BROKER MODULE(S)
+# This directive is used to specify an event broker module that should
+# be loaded by Naemon at startup.  Use multiple directives if you want
+# to load more than one module.  Arguments that should be passed to
+# the module at startup are seperated from the module path by a space.
+#
+# Example:
+#
+#   broker_module=<modulepath> [moduleargs]
+
+#broker_module=/usr/lib/naemon/naemon-livestatus/livestatus.so @cacheDir@/live
+#broker_module=/somewhere/module1.o
+#broker_module=/somewhere/module2.o arg1 arg2=3 debug=0
+
+# In order to provide drop-in support for new modules, you can also make use of
+# the include_dir directive. The include_dir directive causes Naemon to parse
+# any configuration (not just object configuration, as with cfg_dir) as if the
+# contents of the files in the pointed-to directory was included on this line.
+# The path to the directory is relative to the path of the main naemon.cfg
+# file.
