How can I obtain a license?​

  • You can request your token for the free IT-100 edition on our website.
  • If you have purchased a license, request your license files from our support team.

Types of licenses​

According to your Centreon edition, your license can be:

  • online: uses a token. Your Centreon platform must be connected to the internet.
  • offline: uses one or several license files

Which modules require a license?​

The following modules need to be installed separately and require a valid license.

Viewing license-based modules​

Go to Administration > Extensions > Manager. All modules currently installed on your platform have a green button with a white tick mark in it. Modules that require a license have a colored banner at the bottom (red if you have no valid license, green if you have one).


Adding a license to your Centreon platform​

Refer to the tables of network flows to integrate your monitoring platform.

To use an online license, your Centreon platform must be connected to the internet.

Check the connection to internet​

Make sure your Centreon platform is allowed to reach the internet:

  • Check that the machine can access this URL:

  • If needed, set a proxy server:

    • Go to the Administration > Parameters > Centreon UI page, then Proxy options section.
    • Click on Test Internet Connection. The "Connection Successful" message should appear.

Add your license​

  1. Make sure you have your license token (provided by our support team).

  2. Go to Administration > Extensions > Manager.

  3. Click on Add Token. A popup window appears.

  4. Paste your token in the popup window, then click on Add.

    • If your token contains one license, a confirmation message appears.

    • If your token contains several licenses, choose the license you want and then click on Choose.

    Press Esc to close the popup window. The license is applied and the corresponding modules display their validity date:

Troubleshooting licenses​

No valid file uploaded​


Check the contents of the following directory:

ls -lah /etc/centreon/license.d/

If the directory already contains licences with rights that are not apache/apache, delete them or change their rights so that they can be overwritten by the new licenses:

chown apache:apache /etc/centreon/license.d/*
chmod 640 /etc/centreon/license.d/*

Your EPP license is not valid​

  • Check that the fingerprint of the central server (on page Administration > Extensions > Manager) matches the fingerprint in the license.

    less /etc/centreon/license.d/epp.license
  • Check that you do not have more hosts than your license allows. To know the total number of hosts you are supervising, go to Configuration > Hosts > Hosts, and then use the dropdown list to the right above the list of hosts:


    You can also use the following command:

    SELECT COUNT(*) FROM WHERE host_register='1';
