Hi, if you have a large number of machines to check, distant sites (or for any other reason), it may be interresting to use distributed architecture.
For that, we will use satelittes.

You could find further explanations on Centreon offitial wiki here:

http://en.doc.centreon.com/DistributedArchitecture

The installation process is simpler (and faster) as you’ll only need the nagios part.

After installing our working monitoring solution, it could be useful to have also logs available inside our monitoring web interface.
For that purpose we will use these ressources:

You will need Centreon-Syslog installation files. Please go to http://forge.centreon.com/ and register. You’ll be able to download sources after that:

http://forge.centreon.com/projects/list_files/centreon-syslog

Download the stable release (when I wrote, it was the 1.2.1 version). After getting the frontend and server files, transfer them on your server with WinSCP or any other tools you like.

WinSCP is available as setup or portable version http://winscp.net/eng/download.php Continue reading »

Hi again, before starting the installation process, let define some rules we will follow: I recommend that before you start any installation you define a template for the naming scheme of your monitored machines. I decided to uses this one (but it’s up to you to create your own): 3 first letters for customer-name of the machine-environment. In my case it’s ACT-CENTREON-TEST (ACT for ACTIVLAN, Centreon for my computer and test for the target environment) for the central monitoring machine. Continue reading »
