Add a Remote Server to configuration

Configure a new Remote Server​

As of Centreon version 18.10, a new wizard has been added for defining a new Remote Server on the Centreon platform.

Go to the Configuration > Pollers menu and click on Add server with wizard to configure a new Remote Server.

Select Add a Centreon Remote Server and click on Next:


If you enabled the Remote Server option when installing your server, select the option Select a Remote Server, then select your server and fill in the form:


Otherwise, select the Manual input option and fill in the form:


The Database username and Database password are the credentials defined during the installation of the Remote Server.

The Server IP address field is of the following form: [(http|https)://]@IP[:(port)]. If your Remote Server is only available on HTTPS, it is mandatory to define the HTTP method and the TCP port is this one is not the default one.

The Do not check SSL certificate validation option allows to connect to the Remote Server using self-signed SSL certificate.

The Do not use configured proxy tp connect to this server allows to connect to the Remote Server without using the proxy configuration of the Centreon Central server.

Click on Next.

Select the poller(s) to be linked to this Remote Server, then click on Apply:


The wizard will configure your new server:


The Remote Server is now configured:


Enable communication​

The communication between a Central and a Remote Server is ensured by Gorgone and can be done using ZMQ (with a Gorgone running on the Remote Server, recommended) or using SSH protocol.

Select communication type​

Edit the newly created Remote Server configuration, and select ZMQ as Gorgone connection protocol. Define the suitable port (port 5556 is recommended).


Click on Save.

Note that the SSH Legacy port is not used anymore and will be removed.

If you were using it in custom scripts, consider changing to use Gorgone communication system.

Display Gorgone configuration​

From the Pollers listing, click on the Display Gorgone configuration action icon on the line corresponding to your Remote Server image

A pop-in will show the configuration to copy into the Remote Server terminal. Click on Copy to clipboard.


Paste the content of the clipboard directly into the Remote Server terminal as it contains the following content, and will fill the right file:

cat <<EOF > /etc/centreon-gorgone/config.d/40-gorgoned.yaml

Hit the Enter key for the command to be applied.

You can copy the configuration in a custom file by copying the content from the popin.

Restart Gorgone daemon​

From the Remote Server, run the following command to restart Gorgone service:

systemctl restart gorgoned

Make sure it is started by running the following command:

systemctl status gorgoned

It should result as follow:

To force the Central's Gorgone daemon to connect to the Remote Server, restart it with the following command from the Central server:

systemctl restart gorgoned

Export the configuration​

From the Pollers listing, select the Remote Server and click on Export configuration.

Then check the three first boxes and click on Export:


Finally, from the Remote Server, start/restart the collect processes:
