Yes, htop. And occasionally I'm in the mood for btop.

It shows you all the usual stuff, but as a bonus, you’ll also get disk I/O and temperature sensors.

If you’re maxing out your CPU, you’ll know which application is doing it and how hot the CPU is.

I'm probably older than most of you, and I'm not going for the "get off my lawn" answer like the rest of you. Mission center - because graphical user interfaces add value

I like bashtop!

come system monitor, even on other desktop environments

I use htop over SSH, otherwise any DE I'm using usually provides one and I use that.

Well, I was going to say GNOME's System Monitor which has always been the default GUI task manager on my distro, but it's been getting steadily more and more GNOME-ified with every revision and frankly, I hate how it looks now.

Might be time to shop for an alternative.

Edit +44 mins: So, the immediate alternatives all have other things I don't like about them, but an older version of GNOME System Monitor will still install and run, so I guess I'll be using that for now. ¯\_(ツ)_/¯

Usually have tmux split into panes with htop, nmon and nload running whilst I'm doing whatever in the final quadrant

It's interesting to watch what happens on my NAS when I run a backup, to see that the CPU, network and disks don't do what you think they'll do when they do whatever they're doing
