Nagios + Centreon: Guía de instalación y configuración

Nagios es un sistema de monitorización de redes ampliamente utilizado, de código abierto, que vigila los equipos y servicios que se especifiquen, alertando cuando el comportamiento de los mismos no sea el deseado. Entre sus características principales figuran la monitorización de servicios de red (SMTP, POP3, HTTP, SNMP…), la monitorización de los recursos de sistemas hardware (carga del procesador, uso de los discos, memoria, estado de los puertos…), independencia de sistemas operativos, posibilidad de monitorización remota mediante túneles SSL cifrados o SSH, y la posibilidad de programar plugins específicos para nuevos sistemas.

Centreon es un software de monitorización también de software libre que proveniente de nagios pero con motores propios. En este caso se usará nagios como sistema de monitorización y centreon como front-end de centreon.

  1. ola amigo poderia me informar qual a versão do Nagios que foi usada para a instalação ?
    e se possivel me dizer até qual versão do nagios eu consigo usar com o centreon 2.6 ?

  2. Hola! He seguido las instrucciones perfectamente(creo). Al entrar por primera vez a Centreon, al asistente, no me deja elegir nagios como monitoring engine, solo centreon. Qué puedo estar olvidando?
    Saludos y gracias.

  3. Buenas .
    Muy buen post – me ha sido de gran ayuda.
    Sin embargo se me ha presentado el siguiente problema, y necesito de la ayuda de ustedes.

    Realice la instalacion completa de Nagios + Centreon sin ningun poblema. Pero cuando llego al paso N° 7 (Interfaz Web) me aparece el siguiente error:

    7. Installation
    Configuration database OK
    Storage database OK
    Utils database OK
    Creating database user OK
    Setting up basic configuration OK
    Setting up configuration file Could not find CENTREON_ETC. Session probably expired.

    Me podrian decir cual es la solucion a este problema o mas bien en que me he equivocado.

    De ante mano, muchas gracias.
