How to translate Centreon

If you want to contribute to translate Centreon, this new tutorial is for you! Discover how to translate Centreon web interface and how to help us to add new language in Centreon.

Install translation environment

Contact us to obtain an archive of the contents to translate, then copy this archive to a Linux server.

Execute the following commands:

cd centreon-translation

Your environment to translate Centreon is now ready.

First generation

During the first generation, the script will clone Centreon sources from GitHub on your server.

Execute the following command:


At the end of execution, two files are available:

  • messages.pot to translate Centreon web interface menu and forms
  • help.pot to translate help tooltips in configuration forms

Rename messages.pot to messages.po and help.po to help.po

You can now start translation of Centreon by editing files with a PO file editor like poedit.

Keep always your *.po files for next translation.

Use your translation

On your Centreon server, install gettext:

sudo yum install gettext

Create the locale directory for your Centreon:

sudo mkdir -p /usr/share/centreon/www/locale/`locale | grep LC_MESSAGES | cut -d \" -f 2`/LC_MESSAGES

/usr/share/centreon is the Centreon installed directory.

If you want to translate Centreon in other language than use by your Centreon server, you have to define manually the locale.

For example, for Brazilian users, execute the following command:

sudo mkdir -p /usr/share/centreon/www/locale/pt_BR.UTF-8/LC_MESSAGES

Compile translated files:

msgfmt messages.po -o
msgfmt help.pot -o
php ./centreon-github/bin/centreon-translations.php pt centreon-github/lang/pt_BR.UTF-8/LC_MESSAGES/messages.po centreon-github/lang/pt_BR.UTF-8/LC_MESSAGES/messages.ser

Copy compiled translated files:

sudo cp *.mo /usr/share/centreon/www/locale/`locale | grep LC_MESSAGES | cut -d \" -f 2`/LC_MESSAGES
sudo cp messages.ser /usr/share/centreon/www/locale/`locale | grep LC_MESSAGES | cut -d \" -f 2`/LC_MESSAGES

Change rights on directory:

sudo chown -R apache.apache /usr/share/centreon/www/locale/`locale | grep LC_MESSAGES | cut -d \" -f 2`

Restart Apache:

systemctl restart httpd

Connect to your Centreon web interface, edit your profile and select new language:


Save the form and access to another menu, your interface will be translated.

Upgrade translation

Centreon developers released every month a new version of Centreon Web. So translation could be modified with every new release.

To maintain translation up-to-date follow this steps:


At the end of execution, two files up-to-date are available:

  • messages.pot to translate Centreon Web interface menu and forms
  • help.pot to translate help tooltips in configuration forms

Merge this files with previous translation (messages.po and help.po):

msgmerge help.po help.pot -o new_help.po
msgmerge messages.po messages.pot -o new_messages.po

Follow chapter “Use your translation” to upgrade translation for Centreon.
