############################################################################## # # NAGIOS.CFG - Sample Main Config File for Nagios @VERSION@ # # 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=@localstatedir@/nagios.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=@sysconfdir@/objects/commands.cfg cfg_file=@sysconfdir@/objects/contacts.cfg cfg_file=@sysconfdir@/objects/timeperiods.cfg cfg_file=@sysconfdir@/objects/templates.cfg # Definitions for monitoring the local (Linux) host cfg_file=@sysconfdir@/objects/localhost.cfg # Definitions for monitoring a Windows machine #cfg_file=@sysconfdir@/objects/windows.cfg # Definitions for monitoring a router/switch #cfg_file=@sysconfdir@/objects/switch.cfg # Definitions for monitoring a network printer #cfg_file=@sysconfdir@/objects/printer.cfg # You can also tell Nagios to process all config files (with a .cfg # extension) in a particular directory by using the cfg_dir # directive as shown below: #cfg_dir=@sysconfdir@/servers #cfg_dir=@sysconfdir@/printers #cfg_dir=@sysconfdir@/switches #cfg_dir=@sysconfdir@/routers # OBJECT CACHE FILE # This option determines where object definitions are cached when # Nagios 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 Nagios starts. object_cache_file=@localstatedir@/objects.cache # PRE-CACHED OBJECT FILE # This options determines the location of the precached object file. # If you run Nagios 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 Nagios 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 Nagios process if you've got a large and/or complex configuration. # Read the documentation section on optimizing Nagios to find our more # about how this feature works. precached_object_file=@localstatedir@/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. resource_file=@sysconfdir@/resource.cfg # STATUS FILE # This is where the current status of all monitored services and # hosts is stored. Its contents are read and processed by the CGIs. # The contents of the status file are deleted every time Nagios # restarts. status_file=@localstatedir@/status.dat # STATUS FILE UPDATE INTERVAL # This option determines the frequency (in seconds) that # Nagios will periodically dump program, host, and # service status data. status_update_interval=10 # NAGIOS USER # This determines the effective user that Nagios should run as. # You can either supply a username or a UID. nagios_user=@nagios_user@ # NAGIOS GROUP # This determines the effective group that Nagios should run as. # You can either supply a group name or a GID. nagios_group=@nagios_grp@ # EXTERNAL COMMAND OPTION # This option allows you to specify whether or not Nagios should check # for external commands (in the command file defined below). # By default Nagios will check for external commands. # If you want to be able to use the CGI command interface # you will have to enable this. # Values: 0 = disable commands, 1 = enable commands check_external_commands=1 # EXTERNAL COMMAND FILE # This is the file that Nagios 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=@localstatedir@/rw/nagios.cmd # QUERY HANDLER INTERFACE # This is the socket that is created for the Query Handler interface #query_socket=@localstatedir@/rw/nagios.qh # LOCK FILE # This is the lockfile that Nagios will use to store its PID number # in when it is running in daemon mode. lock_file=@subsyslockfile@ # TEMP FILE # This is a temporary file that is used as scratch space when Nagios # updates the status log, cleans the comment file, etc. This file # is created, used, and deleted throughout the time that Nagios is # running. temp_file=@localstatedir@/nagios.tmp # TEMP PATH # This is path where Nagios can create temp files for service and # host check results, etc. temp_path=@TMPDIR@ # EVENT BROKER OPTIONS # Controls what (if any) data gets sent to the event broker. # Values: 0 = Broker nothing # -1 = Broker everything # = See documentation event_broker_options=-1 # EVENT BROKER MODULE(S) # This directive is used to specify an event broker module that should # by loaded by Nagios 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 separated from the module path by a space. # #!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! # WARNING !!! WARNING !!! WARNING !!! WARNING !!! WARNING !!! WARNING #!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! # # Do NOT overwrite modules while they are being used by Nagios or Nagios # will crash in a fiery display of SEGFAULT glory. This is a bug/limitation # either in dlopen(), the kernel, and/or the filesystem. And maybe Nagios... # # The correct/safe way of updating a module is by using one of these methods: # 1. Shutdown Nagios, replace the module file, restart Nagios # 2. Delete the original module file, move the new module file into place, # restart Nagios # # Example: # # broker_module= [moduleargs] #broker_module=/somewhere/module1.o #broker_module=/somewhere/module2.o arg1 arg2=3 debug=0 # LOG ROTATION METHOD # This is the log rotation method that Nagios should use to rotate # the main log file. Values are as follows.. # n = None - don't rotate the log # h = Hourly rotation (top of the hour) # d = Daily rotation (midnight every day) # w = Weekly rotation (midnight on Saturday evening) # m = Monthly rotation (midnight last day of month) log_rotation_method=d # LOG ARCHIVE PATH # This is the directory where archived (rotated) log files should be # placed (assuming you've chosen to do log rotation). log_archive_path=@localstatedir@/archives # LOGGING OPTIONS # If you want messages logged to the syslog facility, as well as the # Nagios log file set this option to 1. If not, set it to 0. use_syslog=1 # NOTIFICATION LOGGING OPTION # If you don't want notifications to be logged, set this value to 0. # If notifications should be logged, set the value to 1. log_notifications=1 # SERVICE RETRY LOGGING OPTION # If you don't want service check retries to be logged, set this value # to 0. If retries should be logged, set the value to 1. log_service_retries=1 # HOST RETRY LOGGING OPTION # If you don't want host check retries to be logged, set this value to # 0. If retries should be logged, set the value to 1. log_host_retries=1 # EVENT HANDLER LOGGING OPTION # If you don't want host and service event handlers to be logged, set # this value to 0. If event handlers should be logged, set the value # to 1. log_event_handlers=1 # INITIAL STATES LOGGING OPTION # If you want Nagios to log all initial host and service states to # the main log file (the first time the service or host is checked) # you can enable this option by setting this value to 1. If you # are not using an external application that does long term state # statistics reporting, you do not need to enable this option. In # this case, set the value to 0. log_initial_states=0 # CURRENT STATES LOGGING OPTION # If you don't want Nagios to log all current host and service states # after log has been rotated to the main log file, you can disable this # option by setting this value to 0. Default value is 1. log_current_states=1 # EXTERNAL COMMANDS LOGGING OPTION # If you don't want Nagios to log external commands, set this value # to 0. If external commands should be logged, set this value to 1. # Note: This option does not include logging of passive service # checks - see the option below for controlling whether or not # passive checks are logged. log_external_commands=1 # PASSIVE CHECKS LOGGING OPTION # If you don't want Nagios to log passive host and service checks, set # this value to 0. If passive checks should be logged, set # this value to 1. log_passive_checks=1 # GLOBAL HOST AND SERVICE EVENT HANDLERS # These options allow you to specify a host and service event handler # command that is to be run for every host or service state change. # The global event handler is executed immediately prior to the event # handler that you have optionally specified in each host or # service definition. The command argument is the short name of a # command definition that you define in your host configuration file. # Read the HTML docs for more information. #global_host_event_handler=somecommand #global_service_event_handler=somecommand
