Hi,
Using Nagios XI, is there a way to assign a new template to multiple hosts/services at once?

Yes, you can apply a template to a hostgroup, so all of the hosts in that group would use it.

This is not working if you want to define mandatory parameters in Host/Service via template assigned to Host/Service group
You need to populate those parameters using the Host/Service config itself, or using template but assigned it to Service/Host itself.

It actually is not possible to assign a host template to a hostgroup directly. When you set the hostgroup parameter in a host template, you are saying that any host using that template should be in that hostgroup.

Correct

Not easily. You can do so through a custom complex sql query among even less accessible methods. If you are going to do a bunch of configuration through templates, my suggestion is get some base templates created and applied to all the objects in some type of logical breakdown so that in the future you can add templates to the pre-existing templates to expand the options pulled in. If you are looking to alter some objects that all share the same xi_wizard_* template, you could always add your new template to the wizard template.
