Centreon Open Source Policy

Thanks to the history of Centreon and the background of our collaborators, we acknowledge the importance of being good Open Source citizens. This translates into concrete statements that we want to publicly make so that we are bound by them: together, they form this Centreon Open Source Policy.

Centreon Open Source Policy


New Open Source contributions for the Centreon project are licensed under the Apache 2.0 license.

Due to the complex history of the project, the project also includes code under other licenses, mostly the GPL 2.0 license.

Contributing to the Centreon project

The Centreon project is open to everyone to contribute. As with every Open Source project, contributions can be code, documentation, bug reports, helping others, and more!

We are reactive to contributions as we are aware that this is a key factor in the experience of a contributor. We are open to contributions that are not directly related to the existing roadmap developed by Centreon. As maintainers, we may not accept some contributions, for instance if the quality standards are not met or if the contributions push the project in a direction that is not desired.

In the interest of fostering an open and welcoming environment, we have defined a Code of Conduct to make participation in our project and our community a harassment-free experience for everyone.

For more details on how to contribute code, please refer to the detailed Contribution Guidelines.

Use of Open Source software at Centreon

Centreon is a heavy user of open source, both because the Centreon project depends on dozens of open source components and because we use Open Source solutions on a daily basis to build our solutions.

We are grateful to the community for all the software that we rely upon and publicly recognize the projects without which Centreon would not be what it is today.

Contributions from Centreon to Open Source projects

Centreon is not just a user of Open Source projects, but also a contributor to those projects, always with an upstream-first policy: we report bugs to the projects and we contribute fixes and features whenever we have the ability to do so. Contributing back takes time, but we believe that it is the right thing to do and that it will be beneficial to everyone, including Centreon, in the long term.

Our contributions to Open Source projects respect the development models, the contribution policies and the licenses of the projects.

While we have an upstream-first policy, we acknowledge that there are rare cases where Centreon may want to push a project in a direction that is incompatible with the direction of the upstream Open Source project. After discussing with the upstream community, Centreon may decide to fork the project in such cases. Forks have played a key role in the history of Open Source, and having the ability to fork as a last resort is a strong benefit of Open Source.

Participation to the global Open Source community

The Open Source community is more than a set of Open Source projects. The community is also about the Open Source philosophy in general, about sharing knowledge and experience, and about meeting individuals and having fun together!

This is why Centreon also contributes to the global Open Source community by sponsoring and participating in local and global events such as FOSDEM, Paris Open Source Experience, OW2con. Centreon is also an active member of several non-profit organizations that are promoting Open Source (April, OW2).
