On a big installation, it would be good to have a checkbox for users to not allow filter data without specifying host group.
Suggested behaviour would be:
If we go to "Monitoring" => "Latest data" and the filtering is empty:
then nothing happens. Must specify at least one host group or hostname.
This behaviour should be customizable somewhere under the "Administration" section.
Right now, as a workaround, a user can use the search field to enter "Latest data" page for a "host" or "host group".
Sadly, new users can still overload the web server and database by accidentally hitting the "Latest data" page. We want to prevent this by having this checkbox.
