This is my first question on this forum, so please correct me if necessary.
We have a number of monitoring servers running ubuntu 16.04,18.04 and nagios and I want to give nsca-ng a try for passive checks. It should be completely compatable with nagios, however when I try installing nsca-ng-server, apt wants to install icinga-common and icinga-core as dependencies. Now I've read about Icinga and it is interesting, but for now not an option to simply replace nagios with icinga. I also don't see why this dependency is there at all since it is a standalone service. Anyone have a solution to install nsca-ng without pulling in icinga (short of compiling from source) ? Thank you.
