You should require /etc/centreon/conf.pm to retrieve this information.
The centreon database can also be non standard.

I think it could be better if you get this information in the centreon database directly.

@Sims24 can you perform upgrade?

garnier-quentin · 2019-04-11T11:18:14Z

It's still working with version 18.10. For me, it's ok. We can commit that version. We could do some update after.
