To be able to monitor the PHP-FPM service with connections, queue information, process… you’ll need to set the status page.

Once again, I’ve upgraded my wiki (wiki.deimos.fr) and it was really easy with git. We could see some new minor design changes like “<pre>” banners or the login page. Other interesting features are appearing like load time informations for each page edition or embedding Vector theme in the Core. A new extension manager is used called Composer and will try to look at it’s benefits shortly. Once again, thanks Mediawiki !

I think this will be the last post for the Debian installation on MacBook Pro 13’ late 2013.
