Distributed architecture

Description

The distributed architecture is to have two types of entities:

  • A central Centreon server to display information

  • One or more remote servers to collect data

The central Centreon server includes the following items:

  • Centreon web interface

  • Databases (MySQL + RRD)

  • Monitoring Engine

  • Broker

The Poller includes the following items:

  • Monitoring Engine

  • Broker module to forward collected data to a central broker

This architecture is used for:

  • Enable load balancing across multiple remote monitoring servers

  • Network streams isolation: if your monitoring architecture have to monitor a DMZ area, it is easier (and safe) to place a remote server in the DMZ network

Components

Central Centreon server

Many components are used to build a central Centreon server:

  • Apache web server for Centreon web interface

  • MariaDB databases to store Centreon configuration parameters as well as monitoring and performance data

  • The Centcore process is used to send monitoring configuration to the remote server and to manage it

  • A monitoring engine to collect data

  • Collected data are sent to Centreon Broker SQL using cbmod by monitoring engine

  • Centreon Broker SQL allows to store information into MariaDB databases and forward them to Centreon Broker RRD

  • Centreon Broker RRD generates and updates RRD files with data in order to display performance graphs

Poller

Many components are used to build a poller:

  • A monitoring engine to collect data

  • Collected data are sent to Centreon Broker SQL using cbmod by monitoring engine
