Good question, sorry I missed it! CLI tools like atop are still widely preferred on servers because they’re lightweight, available over SSH. On headless systems especially, they’re the practical choice.
That said, GUI tools absolutely have their place, particularly on desktops:
- Stacer
- GNOME System Monitor
- KDE System Monitor
- Netdata (web-based, very detailed)
- Cockpit (web UI for server management)
I still lean toward CLI tools like atop, htop, vmstat, iostat, etc. Search the blog for those,
But GUI and web-based tools can indeed be very helpful.
