That is glances, as has been said in other responses. It is great, visually, takes a bit to start up, and uses a decent amount of resources on his own, but if these are minor inconviniences, it is probably the most informative, well laid out stystem monitors.
For another interesting alternative, my favourite is gotop.
But does it have:
How did you got it to look like that ? The bars at the top, capital letters, the layout...
I couldn't find any doc on its github repo page regarding those modifications.
I should have specified I’ve tried themes, and I’ve seen none I liked. They look extremely unprofessional, and not just that, they are just ugly: icons, have you seen those icons? Fonts? Have anyone using Linux have any clue about fonts, or what? I’m very sure they have, but are all they just busy with their own business?
Also, on r/unixporn the kind of DEs I like, when they have no DE: CLI, broswer, i3wm. Almost no ‘real’ DE: I remember no GNOME, KDE, Cinanmon, any other DE that I’ve been impressed by while scrolling the subreddit (and I’ve been doing that for quite a time). And I gave up trying those horrible themes. Maybe — again — I just don’t know where to look for them? I’ve tried those old KDE-look, GNOME-look websites, but maybe there are communities I’m not familiar with? But again: the talk is not about how well can you customize Linux, but about why is it so horrible out-of-the-box?
After all those disappointments I’m more like a DE-less person at the moment, and I’m comfortable with that. (Say, I like gotop over using Activity Monitor.) But that’s just me. Why won’t regular users get more aesthetically appealing look as default?
Ok, It's a fact that THAT it's a font problem: https://github.com/cjbassi/gotop/issues/18
