This is almost the thing I want and need. What I need is some sort of TUI grafana - Json log splitter/organizer/finder

In my opinion logfile navigator is much better than grafana, I use grafana to view a lot of microservices docker logs, but it's too tedious for me (even if depends on your specific use case).

This one, on the other hand, is cleaner and lets you find what you're looking for quickly. And, last but not least, is much lighter.

Currently working exactly on that https://gitlab.com/makapuf/treewalker (even if it could always use some love)

I use vnlog and feedgnuplot to massage and plot data on the console all the time. It's even less than a tui, but might be what you want.
