Distributed architecture with remote DBMS

Description

The distributed architecture with remote DBMS is to have three types of entities:

  • A central Centreon server to display information
  • A DBMS server to store collected data
  • One or more remote servers to collect data

The central Centreon server includes the following items:

  • Centreon web interface
  • Monitoring Engine
  • Broker
  • RRD files

The DBMS server store information into MySQL databases.

The remote servers include 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
  • Have a remote DBMS

Components

DBMS server

The DBMS server is used only to store Centreon configuration parameters as well as monitoring and performance data into MariaDB databases

Central Centreon server

Many components are used to build a central Centreon server:

  • Apache web server for Centreon web interface
  • The central Centreon server get configuration and collected data from DBMS server
  • 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

Remote monitoring server

Many components are used to build a remote server:

  • 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
