I've been using klogg and if you're more into GUI's then I think it's the best there is. It opens and searches in log files of many gigabytes with easy. It's a simple and clean multiplatform QT app.
I tried lnav about 7-8 years ago and as a terminal junkie I really liked the features.
The only breaking thing was a huge (almost bloated) memory consumption. At that time lnav basically just kept everything in memory. Does anyone did that change?
According to the linked homepage, the memory usage seems decent (few hundred megs for most use cases when working with a 3.3G logfile). There's a screenshot with various tasks and what the peak memory usage is.
At some point you need to keep quite a large context in memory to have both decent performance and useful features (that aren't unbearably slow to use). lnav seems to land at a reasonable middle ground.
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.
This looks great.

The problem with GUIs is that AFAIK they need to be installed on the machine the logs you are reading are on so a heavy install on a server.
Oh yeah! lnav is famous. I remember using it like a decade ago to monitor an array of web servers while at GoDaddy; good ol' times.
First commit is from Sep 13, 2009: https://github.com/tstack/lnav/commit/b4ec432515e95e86ec9d71... . Woah! we’re old.
This is what the UX looked like back in the day: https://github.com/tstack/lnav/commit/bce2caa654160518ec11f6...
Wow, the GitHub mobile app doesn't preview PNGs. TIL
GitHub website does on mobile.

Really appreciate this way to demo it quickly, very nice!

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

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.
If you're fine with CLIs, maybe my Kelora project is worth a look. It's a very flexible log processor with built-in scripting: https://kelora.dev
This looks genuinely useful.
Looks very useful, will give it a go.
This resonates with my use of grep+less: https://github.com/tstack/lnav?tab=readme-ov-file#why-not-ju...
I was looking for something like this, Appreciate it!
very nice, definitely will use it
