Hi,
Maybe in the video from the talk from @berk at the OSMC 2019 you get some information: https://www.youtube.com/watch?v=Jx5UmNvEr2s
But as you know this year was a little bit difficult with Convid-19. So Icinga Conf and OSMC were canceld this year. It’s a pitty, because many of us were certainly very happy to learn new things there and to exchange ideas. 
In this thread you’ll find some information incl. Links to some information: Architecture at icinga (a little bit of criticism ...)
