I can see the benefit of what you've outlined. I really want good representation of journals.

Yet, I'm likely to not start using netdata, because it seems to be 'always online' / dependent on something external. If things are bad enough where I'm looking at logs... maybe I don't have Internet access.

While we retain the data, we don't retain full control over the access to it. This is a pro for some, con for others

I dare say that most who have needs complicated enough to warrant log collection have auth infrastructure, tooling, or knowledge to manage
