Hello,
When you want to use the templates in the configuration of a host, you have to click on the "Create Services link et to the template too" button.
I found an article from 2015 in French from a blog: https://blog.zwindler.fr/2015/04/18/centreon-hostgroups-modeles-dhotes-la-reponse-de-centreon-a-mon- item/
Is the solution given at the time still the same? I am using Centreon 20.04.
Thanks in advance
