Generaly these sites are accessible with your local network or through a VPN but sometimes, the site is far away and is only accessible via internet connection. In most case, it’s located behind a firewall.
We will try to describe how we could set a secured connexion between distant satellite and our central monitoring server using SSH connection.

It will looks like something like that:

Hi,

This post will cover the update process of Centreon Syslog module from version 1.2.1 to version 1.3.2
This update is composed of two parts. The syslog-server (which is updated from version 1.1 to 1.2) and syslog-frontend (which is updated from version 1.2.1 to 1.3.2)
Both are available from Centreon Forge (you have to be registered to get an access):

After getting the frontend and server files, transfer them on your server with WinSCP or any other tools you like.

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.

Merethis has released Centreon 2.1.8 (I’ve missed the 2.1.7 :))
The update is very simple:

cd /usr/local/src
sudo wget http://download.centreon.com/index.php?id=140
sudo tar -xzf centreon-2.1.8.tar.gz
cd centreon-2.1.8
sudo ./install.sh -u /etc/centreon

After accepting the license, simply answer yes to all the questions you’ll see.

When finished, connect to the web interface and follow the “NEXT, NEXT, NEXT” steps.
Your database will be updated twice (from 2.1.6 to 2.1.7 then from 2.1.7 to 2.1.8).

It’s finished.
