Well, they may not be that complex... like I said, I haven't used them
much, so I might be missing how they work.

I agree it makes sense to use this for openshift apps.
I am not sure at all we should use it for non openshift apps.

Sure, but we have a lot of legacy stuff we want to monitor/review logs
The right answer might be to just seperate those two use cases with
different solutions, but then we have 2 things to maintain.
It's probibly going to take some investigation and some proof of concept
