i've modified the hosts.cfg and then in the hosts folder all the different .cfg files to reflect this change. So i have check_period on 24x7 and notification_period on workhours. Please find below a small excerpt from those files, because Nagios still keeps sending out notification emails at night, while it shouldn't do that.
Generic Windows Server Template
and here is an excerpt from one of the hosts files:
Host Template Noshferatu
and yet even with this config and having stopped/started nagios completely, it still won't accept these changes. Any ideas where it could still go wrong or is this a bug?
