Offline/online licenses and connectors
The installation procedures for monitoring connectors are slightly different depending on whether your license is offline or online. Here is a summary of their respective characteristics.
In all cases, adding a license (token for online licenses, license files for offline licenses) is done using the Administration > Extensions > Manager page.
Online license​
With an online license (all Cloud platforms, some OnPrem platforms):
- Your central server/SaaS platform must be connected to the internet.
- The Configuration > Monitoring Connector Manager page always displays the complete catalog of monitoring connectors.
- Available updates are displayed automatically.
Offline license​
With an offline license (ONPrem platforms only):
- It is not mandatory that your platform has an internet connection (it can be located in a DMZ).
- The Configuration > Monitoring Connector Manager page displays only the connectors whose
centreon-pack-*packages are installed on the central platform. - You do not automatically see or retrieve new connectors and updates for installed connectors. To retrieve new connectors and update existing ones, use the following command:
- Alma / RHEL / Oracle Linux 8 & 9
- Debian 11 & 12
dnf install centreon-pack-*
apt install centreon-pack-*
Or, to only update the installed connectors:
- Alma / RHEL / Oracle Linux 8 & 9
- Debian 11 & 12
dnf update centreon-pack-*
apt update && apt install --only-upgrade centreon-pack*
If your platform has no internet connection, you will need to install the updates from a mirror repository. Adapt the following procedure to the connectors repository.
Connector updates and breaking changes​
Bear in mind that some connector updates may introduce breaking changes. In this case, if you were using the connector and you update it, you'll need to modify its configuration so that it works again. Be sure to read the connector release notes before updating a connector.
Connectors for which an update is available are displayed with an arrow icon on a blue background: click on it to install the update.
Automatic plugin installation​
On the Configuration > Monitoring Connector Manager page, if Automatic plugin installation is set to ON, plugins will be updated automatically when you deploy the configuration of a poller that monitors a host or service that uses this plugin.

How do I know what type of license I have?​
If you have already installed your license in the past but don't remember what kind you have, go to Administration > Extensions > Manager.
- If you have a See license button, then your license is an online one.
- If you have an Add token button, then your licence is an offline one.
