Definición de Nagios
Nagios es un sistema open source que permite monitorizar servicios de red (SMTP, POP3, HTTP, NTTP, ICMP, SNMP, etc.) y recursos de un host (carga del procesador, uso de los discos, logs del sistema, estado de los servicios, etc.). También permite notificar el cambio de estado de estos servicios a los contactos indicados, cuando se producza el cambio indicado, vía email, pager (busca), SMS, o cualquier método definido por el usuario.
Instalación de Nagios en GNU Linux Ubuntu Server 8.04.1
Os explicamos en este artículo cómo instalar Nagios en GNU Linux Ubuntu Server 8.04.1, para ells seguiremos los siguientes pasos:
Instalar los paquetes necesarios (Required Packages)
En primer lugar hemos de comprobar en GNU Linux que disponemos de los siguientes paquetes, necesarios para el correcto funcionamiento y administración de Nagios:
* Apache 2.
* GCC compiler and development libraries.
* GD development libraries.
Para instalarlos abriremos una ventana de terminal (si tenemos el modo gráfico de Linux Ubuntu Server instalado) y escribiremos el siguiente comando (para instalar Apache 2):
sudo apt-get install apache2
Si ya está instalado mostrará un mensaje como este:
Leyendo lista de paquetes...
Creando árbol de dependencias...
Leyendo la información de estado...
apache2 ya está en su versión más reciente.
0 actualizados, 0 se instalarán, 0 para eliminar y 22 no actualizados.
AjpdSoft Instalación y configuración de Nagios para monitorizar la red - Instalar los paquetes necesarios (Required Packages)
Este otro:
sudo apt-get install libapache2-mod-php5
AjpdSoft Instalación y configuración de Nagios para monitorizar la red - Instalar los paquetes necesarios (Required Packages)
Y este otro para instalar GCC y GD:
sudo apt-get install build-essential
Si aparece este error:
... 404 Not Found.
No se pudieron obtener algunos archivos, ¿quizás deba ejecutar apt-get update o deba intentarlo de nuevo con --fix-missing?
Ejecutaremos el comando:
sudo apt-get update
Y volveremos a ejecutar el comando anterior. El resultado de la ejecución del comando la puedes ver aquí.
Nota 1: para la versión de Ubuntu 6.10 deberemos ejecutar:
sudo apt-get install libgd2-dev
Nota 2: para la versión de Ubuntu 7.10, el nombre de la la librería gd2 es libgd2-xpm-dev, con lo cual el comando a ejecutar sería:
sudo apt-get install libgd2-xpm-dev
Crear usuario y grupo de seguridad para nagios (Account information)
A continuación crearemos un usuario del sistema Linux para el uso de Nagios (con nombre "nagios" y con contraseña "nagios"), para ello ejecutaremos el siguiente comando:
sudo /usr/sbin/useradd -m nagios
Para establecer la contraseña del usuario "nagios" creado escribiremos el comando Linux:
sudo passwd nagios
Crearemos también un grupo de seguridad llamado "nagios":
sudo /usr/sbin/groupadd nagios
Y añadiremos el usuario "nagios" a este grupo con el comando:
sudo /usr/sbin/usermod -G nagios nagios
Crearemos otro grupo de seguridad para permitirle la ejecución de comandos externos a través de la interfaz web, con nombre "nagcmd":
sudo /usr/sbin/groupadd nagcmd
Añadiremos al grupo creado anteriormente el usuario "nagios":
sudo /usr/sbin/usermod -G nagcmd nagios
También agregaremos a este grupo el usuario de Apache "www-data":
sudo /usr/sbin/usermod -G nagcmd www-data

Descargar fichero instalación Nagios y los plugin necesarios
Tras preparar el sistema Linux instalando los paquetes necesarios y creando los grupos y usuarios, procederemos a descargar el fichero de instalación de Nagios y los Plugin. Para ello, desde la línea de comandos, en primer lugar nos crearemos una carpeta para guardar las descargas, con el comando:
sudo mkdir decargas_nagios
Accedemos al directorio creado con:
cd descargas_nagios
AjpdSoft Instalación y configuración de Nagios para monitorizar la red - Descargar fichero instalación Nagios y los plugin necesarios
Y ejecutaremos el siguiente comando para descargar desde Internet el fichero comprimido de instalación de Nagios 3.0.5 (necesitaremos disponer de conexión a Internet en el equipo Linux Ubuntu):
sudo wget http://osdn.dl.sourceforge.net/sourceforge/nagios/nagios-3.0.5.tar.gz

Antes de continuar, para evitar problemas de permisos en la carpeta donde hemos descargado los ficheros de Nagios, ejecutaremos el comando:
sudo chmod /descargas_nagios 777
Compilar e instalar Nagios
Para finalizar el proceso de instalación de Nagios 3.0.5 descomprimiremos los ficheros descargados y los compilaremos. Para descomprimirlos ejecutaremos el siguiente comando:
tar xzf nagios-3.0.5.tar.gz
Accederemos a la carpeta que ha creado el comando anterior:
cd nagios-3.0.5
Ejecutaremos el script de configuración de Nagios, pasándole como parámetro el nombre del grupo creado anteriormente:
./configure --with-command-group=nagcmd

Si no hay errores (lo indica al final del comando con "Total Warnings" y "Total Errors") podremos iniciar Nagios con el comando:
/etc/init.d/nagios start
AjpdSoft Instalación y configuración de Nagios para monitorizar la red - Iniciar Nagios
Si todo es correcto mostrará:
Starting nagios: done.
Acceso a la administración web de Nagios
Una vez instalado e iniciado Nagios, podremos acceder a la web de administración desde cualquier equipo de la red, tanto con sistema operativo Windows como GNU Linux. En nuestro caso accederemos a Nagios desde un equipo con Windows XP SP3, para ello abriremos un navegador web (como Mozilla Firefox) y escribiremos la siguiente URL:
http://192.168.1.111/nagios
Donde "192.168.1.111" será la IP del equipo donde hayamos instalado Nagios.
Nos pedirá usuario y contraseña, intriduciremos en "Nombre de usuario" el usuario creado en pasos anteriores "nagiosadmin" y la contreseña introducida al crearlo:
AjpdSoft Instalación y configuración de Nagios para monitorizar la red - Acceso a la administración web
El aspecto de la página principal de administración de Nagios versión 3.0.5, desde este página podremos ver el estado actual de los servicios monitorizados, entre otras cosas:
AjpdSoft Instalación y configuración de Nagios para monitorizar la red - Acceso a la administración web
Pulsando en "Service Detail" podremos ver los servicios y equipos actualmente monitorizados por Nagios. Tras la instalación, Nagios sólo monitoriza (como ejemplo) el propio equipo donde ha sido instalado y, dentro de este equipo, monitoriza los servicios de HTTP, PING, SSH, Swap Usage, Total Processes:

Cómo configurar Nagios para monitorizar varios servidores
Fichero de configuración principal nagios.cfg
Desde el servidor con GNU Linux y Nagios, abriremos una ventana de terminal y accederemos a la carpeta que contiene los ficheros de configuración de Nagios, con el comando:
cd /usr/local/nagios/etc
AjpdSoft Instalación y configuración de Nagios para monitorizar la red - Cómo configurar Nagios para monitorizar varios servidores
En primer lugar editaremos el fichero de configuración principal de Nagios (mainfile) llamado "nagios.cfg", lo podremos hacer con cualquier editor, por ejemplo:
sudo nano /usr/local/nagios/etc/nagios.cfg
En este fichero deberemos indicar la carpeta de ficheros .cfg ó el fichero de extensión .cfg que contendrá los hosts que monitorizaremos. En nuestro caso añadiremos una carpeta completa:
/usr/local/nagios/etc/hosts
Para ello añadiremos la siguiente línea (en cualquier parte del fichero nagios.cfg):
cfg_dir=/usr/local/nagios/etc/hosts
Guardaremos los cambios con "Control + O" y cerramos nano GNU nano con "Control + X".
Desde este fichero podremos configurar todos los parámetros generales de Nagios.
Ficheros de grupos hosts, hosts, servidores, equipos, dispositivos a monitorizar
Para indicar a Nagios los servidores, equipos o dispositivos a monitorizar, crearemos la carpeta "hosts", con el comando:
sudo mkdir /usr/local/nagios/etc/hosts
(que es la carpeta donde hemos indicado en nagios.cfg que contendrá los hosts)
Accederemos a ella con:
cd /usr/local/nagios/etc/hosts
En esta carpeta crearemos dos ficheros, por un lado crearemos el fichero que contendrá los grupos de hosts (para agrupar los servidores por "tipo"), por ejemplo con el nombre "grupos.cfg", para ello escribiremos el siguiente comando:
sudo nano /usr/local/nagios/etc/hosts/grupos.cfg
En el editor escribiremos:
define hostgroup {
hostgroup_name terminal-server
alias Servidores de Terminal Server
members srvts1
}
define hostgroup {
hostgroup_name almacenamiento
alias Servidores de Almacenamiento
members srvdatos1, srvdatos2
}
define hostgroup {
hostgroup_name base-datos
alias Servidores de Base de Datos
members srvbd1
}
define hostgroup {
hostgroup_name electronica_red
alias Electrónica de red (routers, switchs)
members router_oficina
}
Os explicamos cada parámetro:
* hostgroup_name: nombre interno del grupo de hosts.
* alias: nombre que se mostrará para identificar el grupo de hosts.
* members: nombre de los hosts (definidos en el mismo u otro fichero de configuración) que pertenecerán a este grupo.
Obviamente, no sabremos los "members" hasta que no creemos el fichero de configuración con los hosts a monitorizar por Nagios. Este fichero "grupos.cfg" podremos editarlo en cualquier momento y agregar los miembros que deseemos.
Crearemos ahora un nuevo fichero con el nombre que queramos y la extensión .cfg, este fichero contendrá la configuración necesaria para agregar los distintos servidores y dispositivos a la monitorización de Nagios. Crearemos este fichero con:
sudo nano /usr/local/nagios/etc/hosts/servidores.cfg
Agregaremos lo siguiente al fichero:
define host {
host_name srvdatos1
alias srvdatos1
address 192.168.1.2
check_command check-host-alive
max_check_attempts 10
notification_interval 0
notification_period 24x7
notification_options d,u,r
notifications_enabled 1
contact_groups contactos_almacenamiento
}
define host {
host_name srvdatos2
alias srvdatos2
address 192.168.1.2
check_command check-host-alive
max_check_attempts 10
notification_interval 0
notification_period 24x7
notification_options d,u,r
notifications_enabled 1
contact_groups contactos_almacenamiento
}
define host {
host_name srvbd1
alias srvbd1
address 192.168.1.100
check_command check-host-alive
max_check_attempts 10
notification_interval 0
notification_period 24x7
notification_options d,u,r
notifications_enabled 1
contact_groups contactos_base_datos
}
define host {
host_name srvts1
alias srvts1
address 192.168.1.150
check_command check-host-alive
max_check_attempts 10
notification_interval 0
notification_period 24x7
notification_options d,u,r
notifications_enabled 1
contact_groups contactos_terminal_server
}
define host {
host_name router_oficina
alias router_oficina
address 192.168.1.1
check_command check-host-alive
max_check_attempts 10
notification_interval 0
notification_period 24x7
notification_options d,u,r
notifications_enabled 1
contact_groups contactos_routers
}
A continuación explicamos algunos de los parámetros:
* host_name: nombre interno del hosts (servidor o dispositivo).
* alias: nombre que identificará el host en el administrador de Nagios.
* address: dirección IP del host o dispositivo.
* check_command: comando que se utilizará para comprobar la disponibilidad del host o dispositivo, normalmente "check-host-alive".
* notifications_enabled: habiltar / deshabilitar las notificaciones en caso de caída de este host o dispositivo ("1" habilitadas las notificaciones, "0" deshabilitadas las notificaciones).
* contact_groups: grupo de contactos a los que se notificará en caso de caída del host o dispositivo.
En este fichero definiremos todos los host (servidores o pcs que queramos monitorizar) y todos los dispositivos (impresoras de red con IP propia, switch con IP, routers, etc.). Por supuesto, se pueden separar en tantos ficheros .cfg como deseemos, puesto que hemos configurado Nagios (nagios.cfg) para que utilice todos los ficheros .cfg de la carpeta /usr/local/nagios/etc/hosts.
Fichero de grupos de contactos y contactos
Deberemos crear también los grupos de contactos, podremos hacerlo en la misma carpeta donde hemos creado los grupos de hosts y hosts, accederemos a esta carpeta:
cd /usr/local/nagios/etc/hosts
Crearemos aquí un fichero con los grupos de contactos, llamado "grupos_contactos.cfg":
sudo nano /usr/local/nagios/etc/hosts/grupos_contactos.cfg
En este fichero introduciremos algo así:
define contactgroup {
contactgroup_name contactos_almacenamiento
alias Contactos aviso servidores almacenamiento
members ajpdsoft, fernando
}
define contactgroup {
contactgroup_name contactos_base_datos
alias Contactos aviso servidores Base de Datos
members fernando, alonso
}
define contactgroup {
contactgroup_name contactos_routers
alias Contactos aviso Electronica de red
members ajpdsoft, fernando, alonso
}
Creando todos los grupos de contactos, para el aviso (en caso de caída) de los servicios, hosts, dispositivos monitorizados. Lo normal es que, dependiendo del servidor a monitorizar, haya que avisar a un grupo u otro de contactos. Por ejemplo, en una organización con cuatro técncios dedidcados a administración de redes y tres técnicos dedicados a administración de base de datos, lo normal será crear dos grupos de contactos, uno para el aviso en caso de caída de la electrónica de red (administradores de redes) y otro para aviso en caso de caída del servidor (o los servicios) de la base de datos (administradores de base de datos).
A continuación crearemos otro fichero que contendrá los contactos propiamente dichos y la información de cada uno (email, nombre, etc.):
sudo nano /usr/local/nagios/etc/hosts/contactos.cfg
Con el contenido:
define contact {
contact_name alonso
alias Alonso J.
host_notifications_enabled 1
service_notifications_enabled 1
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,u,r
service_notification_commands notificar_email
host_notification_commands notificar_email
email alonso_t@ajpdsoft.com
can_submit_commands 1
}
define contact {
contact_name ajpdsoft
alias AjpdSoft
host_notifications_enabled 1
service_notifications_enabled 1
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,u,r
service_notification_commands notificar_email
host_notification_commands notificar_email
email ajpdsoft@ajpdsoft.com
can_submit_commands 1
}
define contact {
contact_name fernando
alias Fernando Alonso
host_notifications_enabled 1
service_notifications_enabled 1
service_notification_period 24x7
host_notification_period 24x7
service_notification_options w,u,c,r
host_notification_options d,u,r
service_notification_commands notificar_email
host_notification_commands notificar_email
email fernando@ajpdsoft.com
can_submit_commands 1
}
Definición de los comandos
En el paso anterior, para el contacto, en el parámetro "service_notification_commands" hemos establecido el comando "notificar_por_email" que hay que definir. Para ello crearemos un nuevo fichero que llamaremos "comandos.cfg" que contendrá todos los comandos que utilicemos definidos:
sudo nano /usr/local/nagios/etc/hosts/comandos.cfg
Con el contenido:
define command {
command_name notificar_email
command_line /usr/bin/printf "%b" "Nagios\n\nTipo: $NOTIFICATIONTYPE$\n
\nServicio: $SERVICEDESC$\nHost: $HOSTALIAS$
\nIP: $HOSTADDRESS$\nEstado: $SERVICESTATE$\n\nFecha: $DATETIME$\n\n
Información:\n\n$OUTPUT$" | /usr/bin/mail -s "** $NOTIFICATIONTYPE$
alert - $HOSTALIAS$/$SERVICEDESC$ is $SERVICESTATE$ **" $CONTACTEMAIL$
}
Nota: el contenido anterior para el parámetro "command_line" va en una sola línea, lo hemos partido para que la línea no quede excesivamente larga en la visulazación del navegador.
Verificación de la configuración introducida
Para que los cambios tengan efecto en Nagios, en primer lugar comprobaremos que la sintaxis introducida es correcta, para ello utilizaremos el comando:
sudo /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
AjpdSoft Instalación y configuración de Nagios para monitorizar la red - Verificación de la configuración introducida
Deberemos asegurarnos de que al compilar no aparezcan errores:
Total Errors: 0
A continuación os mostramos algunos de los posibles errores al compilar los ficheros de configuración de Nagios.
Posibles errores de configuración y su causa y solución
Si hay algún error de sintaxis en algunos de los ficheros .cfg, el comando de verificación anterior nos mostrará algo así:

Warning: Host 'srvts1' has no services associated with it!
Si se produce algún error, como los anteriores, lo solucionaremos editando los ficheros de configuración .cfg (servidores.cfg, grupos.cfg, etc.) indicados en el propio error. Normalmente el comando de verificación suele indicarnos el motivo del error, el fichero donde se produce e incluso la línea del fichero. Tras editarlo y guardar los cambios volveremos a verificar los ficheros con el siguiente comando, hasta que no haya errores (sí puede haber warnings):
sudo /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
Reinicio servicio Nagios y comprobación de la monitorización de los hosts añadidos
Una vez verificados los ficheros de configuración de Nagios para que no haya errores, reiniciaremos el servicio para que se apliquen los cambios, con el comando:
/etc/init.d/nagios restart
Devolverá algo así:
Running configuration check... done.
Stopping nagios: done.
Starting nagios: done.
Ahora podremos acceder a la administración web de Nagios y veremos los nuevos hosts y dispositivos añadidos (desde "Host Detail"):
AjpdSoft Instalación y configuración de Nagios para monitorizar la red - Reinicio servicio Nagios y comprobación de la monitorización de los hosts añadidos
En nuestro caso, hemos configurado los host para que se compruebe su estado mediante un PING, si alguno no está disponible en la red, Nagios, mostrará una aviso como este:
CRITICAL - Host Unreachable (192.168.1.150)
Si el host o dispositivo responde al PING correctamente, Nagios, mostrará un mensage como este en "Status Information":
PING OK - Packet loss = 0%, RTA = 0.16 ms

*** GD, PNG, and/or JPEG libraries could not be located... *********
Boutell's GD library is required to compile the statusmap, trends
and histogram CGIs. Get it from http://www.boutell.com/gd/, compile
it, and use the --with-gd-lib and --with-gd-inc arguments to specify
the locations of the GD library and include files.
NOTE: In addition to the gd-devel library, you'll also need to make
sure you have the png-devel and jpeg-devel libraries installed
on your system.
NOTE: After you install the necessary libraries on your system:
1. Make sure /etc/ld.so.conf has an entry for the directory in
which the GD, PNG, and JPEG libraries are installed.
2. Run 'ldconfig' to update the run-time linker options.
3. Run 'make clean' in the Nagios distribution to clean out
any old references to your previous compile.
4. Rerun the configure script.
NOTE: If you can't get the configure script to recognize the GD libs
on your system, get over it and move on to other things. The
CGIs that use the GD libs are just a small part of the entire
Nagios package. Get everything else working first and then
revisit the problem. Make sure to check the nagios-users
mailing list archives for possible solutions to GD library
problems when you resume your troubleshooting.

*** Compile finished ***
If the main program and CGIs compiled without any errors, you
can continue with installing Nagios as follows (type 'make'
without any arguments for a list of all possible options):
make install
- This installs the main program, CGIs, and HTML files
make install-init
- This installs the init script in /etc/init.d
make install-commandmode
- This installs and configures permissions on the
directory for holding the external command file
make install-config
- This installs *SAMPLE* config files in /usr/local/nagios/etc
You'll have to modify these sample files before you can
use Nagios. Read the HTML documentation for more info
on doing this. Pay particular attention to the docs on
object configuration files, as they determine what/how
things get monitored!
make install-webconf
- This installs the Apache config file for the Nagios
web interface
*** Support Notes *******************************************
If you have questions about configuring or running Nagios,
please make sure that you:
- Look at the sample config files
- Read the HTML documentation
- Read the FAQs online at http://www.nagios.org/faqs
before you post a question to one of the mailing lists.
Also make sure to include pertinent information that could
help others help you. This might include:
- What version of Nagios you are using
- What version of the plugins you are using
- Relevant snippets from your config files
- Relevant error messages from the Nagios log file
For more information on obtaining support for Nagios, visit:

# NAGIOS.CFG - Sample Main Config File for Nagios 3.0.5
#
# 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: 10-15-2008
#
##############################################################################
# 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=/usr/local/nagios/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.
# You can specify individual object config files as shown below:
cfg_file=/usr/local/nagios/etc/objects/commands.cfg
cfg_file=/usr/local/nagios/etc/objects/contacts.cfg
cfg_file=/usr/local/nagios/etc/objects/timeperiods.cfg
cfg_file=/usr/local/nagios/etc/objects/templates.cfg
# Definitions for monitoring the local (Linux) host
cfg_file=/usr/local/nagios/etc/objects/localhost.cfg
# Definitions for monitoring a Windows machine
#cfg_file=/usr/local/nagios/etc/objects/windows.cfg
# Definitions for monitoring a router/switch
#cfg_file=/usr/local/nagios/etc/objects/switch.cfg
# Definitions for monitoring a network printer
#cfg_file=/usr/local/nagios/etc/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=/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=/usr/local/nagios/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=/usr/local/nagios/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=/usr/local/nagios/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=/usr/local/nagios/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=/usr/local/nagios/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=/usr/local/nagios/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=/usr/local/nagios/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
#
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. 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=
#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=/usr/local/nagios/var/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.

# 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.

# 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.

# 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.

# 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
# 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
# SERVICE INTER-CHECK DELAY METHOD
# This is the method that Nagios should use when initially
# "spreading out" service checks when it starts monitoring. The
# default is to use smart delay calculation, which will try to
# space all service checks out evenly to minimize CPU load.
# Using the dumb setting will cause all checks to be scheduled
# at the same time (with no delay between them)! This is not a
# good thing for production, but is useful when testing the
# parallelization functionality.
# n = None - don't use any delay between checks
# d = Use a "dumb" delay of 1 second between checks
# s = Use "smart" inter-check delay calculation
# x.xx = Use an inter-check delay of x.xx seconds
service_inter_check_delay_method=s
# MAXIMUM SERVICE CHECK SPREAD
# This variable determines the timeframe (in minutes) from the
# program start time that an initial check of all services should
# be completed. Default is 30 minutes.
max_service_check_spread=30
# SERVICE CHECK INTERLEAVE FACTOR
# This variable determines how service checks are interleaved.
# Interleaving the service checks allows for a more even
# distribution of service checks and reduced load on remote
# hosts. Setting this value to 1 is equivalent to how versions
# of Nagios previous to 0.0.5 did service checks. Set this
# value to s (smart) for automatic calculation of the interleave
# factor unless you have a specific reason to change it.
# s = Use "smart" interleave factor calculation

max_host_check_spread=30
# MAXIMUM CONCURRENT SERVICE CHECKS
# This option allows you to specify the maximum number of
# service checks that can be run in parallel at any given time.
# Specifying a value of 1 for this variable essentially prevents

#
# Note: Make sure that only one instance of Nagios has access
# to this directory!
check_result_path=/usr/local/nagios/var/spool/checkresults

# This option determines the maximum age (in seconds) which check
# result files are considered to be valid. Files older than this
# threshold will be mercilessly deleted without further processing.
max_check_result_file_age=3600
# CACHED HOST CHECK HORIZON
# This option determines the maximum amount of time (in seconds)
# that the state of a previous host check is considered current.
# Cached host states (from host checks that were performed more
# recently that the timeframe specified by this value) can immensely
# improve performance in regards to the host check logic.
# Too high of a value for this option may result in inaccurate host
# states being used by Nagios, while a lower value may result in a
# performance hit for host checks. Use a value of 0 to disable host
# check caching.

cached_service_check_horizon=15
# ENABLE PREDICTIVE HOST DEPENDENCY CHECKS
# This option determines whether or not Nagios will attempt to execute

# Values:
# 0 = Disable predictive checks
# 1 = Enable predictive checks (default)
enable_predictive_service_dependency_checks=1
# SOFT STATE DEPENDENCIES
# This option determines whether or not Nagios will use soft state
# information when checking host and service dependencies. Normally
# Nagios will only use the latest hard host or service state when
# checking dependencies. If you want it to use the latest state (regardless
# of whether its a soft or hard state type), enable this option.

#time_change_threshold=900
# AUTO-RESCHEDULING OPTION
# This option determines whether or not Nagios will attempt to
# automatically reschedule active host and service checks to

# HOST AND SERVICE PERFORMANCE DATA FILE MODES
# This option determines whether or not the host and service
# performance data files are opened in write ("w") or append ("a")
# mode. If you want to use named pipes, you should use the special
# pipe ("p") mode which avoid blocking at startup, otherwise you will
# likely want the defult append ("a") mode.
#host_perfdata_file_mode=a
#service_perfdata_file_mode=a
# HOST AND SERVICE PERFORMANCE DATA FILE PROCESSING INTERVAL
# These options determine how often (in seconds) the host and service
# performance data files are processed using the commands defined
# below. A value of 0 indicates the files should not be periodically
# processed.
#host_perfdata_file_processing_interval=0
#service_perfdata_file_processing_interval=0
# HOST AND SERVICE PERFORMANCE DATA FILE PROCESSING COMMANDS
# These commands are used to periodically process the host and
# service performance data files. The interval at which the
# processing occurs is determined by the options above.
#host_perfdata_file_processing_command=process-host-perfdata-file
#service_perfdata_file_processing_command=process-service-perfdata-file
# OBSESS OVER SERVICE CHECKS OPTION
# This determines whether or not Nagios will obsess over service
# checks and run the ocsp_command defined below. Unless you're
# planning on implementing distributed monitoring, do not enable
# this option. Read the HTML docs for more information on
# implementing distributed monitoring.
# Values: 1 = obsess over services, 0 = do not obsess (default)
obsess_over_services=0
# OBSESSIVE COMPULSIVE SERVICE PROCESSOR COMMAND
# This is the command that is run for every service check that is
# processed by Nagios. This command is executed only if the
# obsess_over_services option (above) is set to 1. 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 on implementing distributed monitoring.
#ocsp_command=somecommand
# OBSESS OVER HOST CHECKS OPTION
# This determines whether or not Nagios will obsess over host
# checks and run the ochp_command defined below. Unless you're
# planning on implementing distributed monitoring, do not enable
# this option. Read the HTML docs for more information on
# implementing distributed monitoring.
# Values: 1 = obsess over hosts, 0 = do not obsess (default)
obsess_over_hosts=0
# OBSESSIVE COMPULSIVE HOST PROCESSOR COMMAND
# This is the command that is run for every host check that is
# processed by Nagios. This command is executed only if the

#ochp_command=somecommand
# TRANSLATE PASSIVE HOST CHECKS OPTION
# This determines whether or not Nagios will translate
# DOWN/UNREACHABLE passive host check results into their proper
# state for this instance of Nagios. This option is useful
# if you have distributed or failover monitoring setup. In
# these cases your other Nagios servers probably have a different
# "view" of the network, with regards to the parent/child relationship
# of hosts. If a distributed monitoring server thinks a host
# is DOWN, it may actually be UNREACHABLE from the point of
# this Nagios instance. Enabling this option will tell Nagios
# to translate any DOWN or UNREACHABLE host states it receives
# passively into the correct state from the view of this server.
# Values: 1 = perform translation, 0 = do not translate (default)
translate_passive_host_checks=0
# PASSIVE HOST CHECKS ARE SOFT OPTION
# This determines whether or not Nagios will treat passive host
# checks as being HARD or SOFT. By default, a passive host check
# result will put a host into a HARD state type. This can be changed
# by enabling this option.
# Values: 0 = passive checks are HARD, 1 = passive checks are SOFT
passive_host_checks_are_soft=0
# ORPHANED HOST/SERVICE CHECK OPTIONS
# These options determine whether or not Nagios will periodically
# check for orphaned host service checks. Since service checks are
# not rescheduled until the results of their previous execution
# instance are processed, there exists a possibility that some
# checks may never get rescheduled. A similar situation exists for
# host checks, although the exact scheduling details differ a bit
# from service checks. Orphaned checks seem to be a rare
# problem and should not happen under normal circumstances.
# If you have problems with service checks never getting
# rescheduled, make sure you have orphaned service checks enabled.
# Values: 1 = enable checks, 0 = disable checks
check_for_orphaned_services=1
check_for_orphaned_hosts=1
# SERVICE FRESHNESS CHECK OPTION
# This option determines whether or not Nagios will periodically
# check the "freshness" of service results. Enabling this option
# is useful for ensuring passive checks are received in a timely
# manner.
# Values: 1 = enabled freshness checking, 0 = disable freshness checking
check_service_freshness=1
# SERVICE FRESHNESS CHECK INTERVAL
# This setting determines how often (in seconds) Nagios will
# check the "freshness" of service check results. If you have
# disabled service freshness checking, this option has no effect.

# HOST FRESHNESS CHECK OPTION
# This option determines whether or not Nagios will periodically

# ADDITIONAL FRESHNESS THRESHOLD LATENCY
# This setting determines the number of seconds that Nagios
# will add to any host and service freshness thresholds that
# it calculates (those not explicitly specified by the user).
additional_freshness_latency=15
# FLAP DETECTION OPTION
# This option determines whether or not Nagios will try
# and detect hosts and services that are "flapping".
# Flapping occurs when a host or service changes between
# states too frequently. When Nagios detects that a
# host or service is flapping, it will temporarily suppress
# notifications for that host/service until it stops
# flapping. Flap detection is very experimental, so read
# the HTML documentation before enabling this feature!
# Values: 1 = enable flap detection
# 0 = disable flap detection (default)
enable_flap_detection=1
# FLAP DETECTION THRESHOLDS FOR HOSTS AND SERVICES
# Read the HTML documentation on flap detection for
# an explanation of what this option does. This option
# has no effect if flap detection is disabled.

# DATE FORMAT OPTION
# This option determines how short dates are displayed. 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=/usr/local/nagios/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.
