Should my Centreon Map server be on a dedicated server or on the Central ?

Yes, the server has to be installed on a dedicated machine.

The main reason is that if your Centreon Map server start requiring a lot of resources (because many users are connected or your Broker is sending a lot of events for instance), it will not affect your Central server performance.

Are resources not yet deployed in real time displayed in Centreon Map ?

Yes, when you add a new resource to your Centreon, it’s automatically displayed and accessible in Centreon Map desktop client, in the ‘Resources’ panel.


We did that so you can already start making your views before starting the monitoring. By doing so, you can prepare all your monitoring environment and, when you deploy your configuration, you already have fully functionnal monitoring from Centreon Map.

Can I access my views through a mobile or a tablet ?

Centreon Map web client is not responsive but you can access all your views from a mobile device by using the web client. The rendering will be perfectible but it will work. Whether you are using an Android, an IPhone, a Blackberry or a Windows phone device, you can access them as long as your device has a web browser.

However, your mobile device must have access to your Centreon Map server on the port used by your Centreon Map server (8080 for classic configuration, 8443 for secured configuration). If not, you will have an authentication error displayed on the web client.

How to change Centreon Map port ?

By default your Centreon Map server is listening and sending information through the port 8080. If you have set the SSL (cf SSL configuration with a recognized key) the port is 8443.

You can change this port (if, for instance, you have a firewall on your network blocking these ports).


If the new port you want to set is lower than 1024, please follow these instructions instead.

On your Centreon Map server, stop tomcat

# systemctl stop tomcat

Edit the server.xml settings file located in /etc/tomcat/server.xml

# vim /etc/tomcat/server.xml

And, in the following lines

<Connector port="8080"
            redirectPort="8443" />

replace port=”8080” by the port you want.

Then restart your tomcat

# systemctl start tomcat

Wait for tomcat to start (~30 sec to 1 or 2 minutes) test that your server is up and accessible on the new port you defined by entering the following URL in your web browser:


How to change Centreon Map port under 1024

You may want to setup your server to listen and send data through ports under 1024, such as port 80 or 443 (as these ports are rarely blocked by any firewall).

In the case where you want to set a port lower than 1024, the method is different since all ports under 1024 have a restricted access and only special applications can access them.

There are a few different methods to get around this issue. We are going to focus on one of them: Create a port forwading thanks to the firewall.


For this example, let’s say we want to make our Map 4 server listen and send data through the port 80.

In your case, replace each occurences of 80 by the port you want to use.

  1. Check that your firewall is running

On you Map 4 server, check that your firewall is running by executing the following command:

# systemctl status iptables
Table: raw
num  target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
num  target     prot opt source               destination

Table: mangle
num  target     prot opt source               destination

If your firewall is stopped you will see the following output:

iptables: Firewall is not running.

Start it by executing:

# systemctl start iptables
  1. Allow a connection on the port you want your Map 4 to listen and send data

Enter the following lines in your console:

# /sbin/iptables -A OUTPUT -p tcp --dport 80 -j ACCEPT
# /sbin/iptables -A INPUT -p tcp --dport 80 -j ACCEPT
  1. Add the port forwarding

Execute the following line in your console:

# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080
  1. Restart and save

Restart your firewall:

# systemctl restart iptables

Save this configuration so it will be applied on each reboot of your server

# /sbin/iptables save

You are all set ! Your Centreon Map server is now accessible on the 80 port. To check it, enter the following URL in your browser:
