############################################################################## # # NAGIOS.CFG - Sample Main Config File for Nagios 3.1.0 # # 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. # # Last Modified: 12-14-2008 # ############################################################################## # 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=var/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. # Note: A relative path here is relative to the location of the overall nagios.cfg file, # not relative to the current directory cfg_file=minimal.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=/usr/local/nagios/etc/servers #cfg_dir=/usr/local/nagios/etc/printers #cfg_dir=/usr/local/nagios/etc/switches #cfg_dir=/usr/local/nagios/etc/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=var/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=var/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=etc/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=var/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 # 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 # 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 *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. # Values: 0 = disable commands, 1 = enable commands check_external_commands=1 # EXTERNAL COMMAND CHECK INTERVAL # This is the interval at which Nagios should check for external commands. # This value works of the interval_length you specify later. If you leave # that at its default value of 60 (seconds), a value of 1 here will cause # Nagios to check for external commands every minute. If you specify a # number followed by an "s" (i.e. 15s), this will be interpreted to mean # actual seconds rather than a multiple of the interval_length variable. # Note: In addition to reading the external command file at regularly # scheduled intervals, Nagios will also check for external commands after # event handlers are executed. # NOTE: Setting this value to -1 causes Nagios to check the external # command file as often as possible. #command_check_interval=15s command_check_interval=-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=var/rw/nagios.cmd # EXTERNAL COMMAND BUFFER SLOTS # This settings is used to tweak the number of items or "slots" that # the Nagios daemon should allocate to the buffer that holds incoming # external commands before they are processed. As external commands # are processed by the daemon, they are removed from the buffer. external_command_buffer_slots=4096 # 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=var/nagios.lock # 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=var/nagios.tmp # TEMP PATH # This is path where Nagios can create temp files for service and # host check results, etc. temp_path=/tmp # 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 seperated 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.

Valid options # include: # us (MM-DD-YYYY HH:MM:SS) # euro (DD-MM-YYYY HH:MM:SS) # iso8601 (YYYY-MM-DD HH:MM:SS) # strict-iso8601 (YYYY-MM-DDTHH:MM:SS) # date_format=us # TIMEZONE OFFSET # This option is used to override the default timezone that this # instance of Nagios runs in. If not specified, Nagios will use # the system configured timezone. # # NOTE: In order to display the correct timezone in the CGIs, you # will also need to alter the Apache directives for the CGI path # to include your timezone. Example: # # # SetEnv TZ "Australia/Brisbane" # ... # #use_timezone=US/Mountain #use_timezone=Australia/Brisbane # P1.PL FILE LOCATION # This value determines where the p1.pl perl script (used by the # embedded Perl interpreter) is located. If you didn't compile # Nagios with embedded Perl support, this option has no effect. p1_file=/usr/local/nagios/bin/p1.pl # EMBEDDED PERL INTERPRETER OPTION # This option determines whether or not the embedded Perl interpreter # will be enabled during runtime. This option has no effect if Nagios # has not been compiled with support for embedded Perl. # Values: 0 = disable interpreter, 1 = enable interpreter enable_embedded_perl=1 # EMBEDDED PERL USAGE OPTION # This option determines whether or not Nagios will process Perl plugins # and scripts with the embedded Perl interpreter if the plugins/scripts # do not explicitly indicate whether or not it is okay to do so. Read # the HTML documentation on the embedded Perl interpreter for more # information on how this option works. use_embedded_perl_implicitly=1 # ILLEGAL OBJECT NAME CHARACTERS # This option allows you to specify illegal characters that cannot # be used in host names, service descriptions, or names of other # object types. illegal_object_name_chars=`~!$%^&*|'"<>?,()= # ILLEGAL MACRO OUTPUT CHARACTERS # This option allows you to specify illegal characters that are # stripped from macros before being used in notifications, event # handlers, etc. This DOES NOT affect macros used in service or # host check commands. # The following macros are stripped of the characters you specify: # $HOSTOUTPUT$ # $HOSTPERFDATA$ # $HOSTACKAUTHOR$ # $HOSTACKCOMMENT$ # $SERVICEOUTPUT$ # $SERVICEPERFDATA$ # $SERVICEACKAUTHOR$ # $SERVICEACKCOMMENT$ illegal_macro_output_chars=`~$&|'"<> # REGULAR EXPRESSION MATCHING # This option controls whether or not regular expression matching # takes place in the object config files. Regular expression # matching is used to match host, hostgroup, service, and service # group names/descriptions in some fields of various object types. # Values: 1 = enable regexp matching, 0 = disable regexp matching use_regexp_matching=0 # "TRUE" REGULAR EXPRESSION MATCHING # This option controls whether or not "true" regular expression # matching takes place in the object config files. This option # only has an effect if regular expression matching is enabled # (see above). If this option is DISABLED, regular expression # matching only occurs if a string contains wildcard characters # (* and ?). If the option is ENABLED, regexp matching occurs # all the time (which can be annoying). # Values: 1 = enable true matching, 0 = disable true matching use_true_regexp_matching=0 # ADMINISTRATOR EMAIL/PAGER ADDRESSES # The email and pager address of a global administrator (likely you). # Nagios never uses these values itself, but you can access them by # using the $ADMINEMAIL$ and $ADMINPAGER$ macros in your notification # commands. admin_email=nagios@localhost admin_pager=pagenagios@localhost # DAEMON CORE DUMP OPTION # This option determines whether or not Nagios is allowed to create # a core dump when it runs as a daemon. Note that it is generally # considered bad form to allow this, but it may be useful for # debugging purposes. Enabling this option doesn't guarantee that # a core file will be produced, but that's just life... # Values: 1 - Allow core dumps # 0 - Do not allow core dumps (default) daemon_dumps_core=0 # LARGE INSTALLATION TWEAKS OPTION # This option determines whether or not Nagios will take some shortcuts # which can save on memory and CPU usage in large Nagios installations. # Read the documentation for more information on the benefits/tradeoffs # of enabling this option. # Values: 1 - Enabled tweaks # 0 - Disable tweaks (default) use_large_installation_tweaks=0 # ENABLE ENVIRONMENT MACROS # This option determines whether or not Nagios will make all standard # macros available as environment variables when host/service checks # and system commands (event handlers, notifications, etc.) are # executed. Enabling this option can cause performance issues in # large installations, as it will consume a bit more memory and (more # importantly) consume more CPU. # Values: 1 - Enable environment variable macros (default) # 0 - Disable environment variable macros enable_environment_macros=1 # CHILD PROCESS MEMORY OPTION # This option determines whether or not Nagios will free memory in # child processes (processed used to execute system commands and host/ # service checks). If you specify a value here, it will override # program defaults. # Value: 1 - Free memory in child processes # 0 - Do not free memory in child processes #free_child_process_memory=1 # CHILD PROCESS FORKING BEHAVIOR # This option determines how Nagios will fork child processes # (used to execute system commands and host/service checks). Normally # child processes are fork()ed twice, which provides a very high level # of isolation from problems. Fork()ing once is probably enough and will # save a great deal on CPU usage (in large installs), so you might # want to consider using this. If you specify a value here, it will # program defaults. # Value: 1 - Child processes fork() twice # 0 - Child processes fork() just once #child_processes_fork_twice=1 # DEBUG LEVEL # This option determines how much (if any) debugging information will # be written to the debug file. OR values together to log multiple # types of information. # Values: # -1 = Everything # 0 = Nothing # 1 = Functions # 2 = Configuration # 4 = Process information # 8 = Scheduled events # 16 = Host/service checks # 32 = Notifications # 64 = Event broker # 128 = External commands # 256 = Commands # 512 = Scheduled downtime # 1024 = Comments # 2048 = Macros debug_level=0 # DEBUG VERBOSITY # This option determines how verbose the debug log out will be. # Values: 0 = Brief output # 1 = More detailed # 2 = Very detailed debug_verbosity=1 # DEBUG FILE # This option determines where Nagios should write debugging information. debug_file=var/nagios.debug # MAX DEBUG FILE SIZE # This option determines the maximum size (in bytes) of the debug file. If # the file grows larger than this size, it will be renamed with a .old # extension. If a file already exists with a .old extension it will # automatically be deleted. This helps ensure your disk space usage doesn't # get out of control when debugging Nagios. max_debug_file_size=1000000
