Htop 3.0
For those who like htop-style system monitoring tools, you should also keep these commands handy:- atop (great for finding out what's causing system-wide slowness when you're not sure whether it's CPU/disk/network/temperature/etc.)- iotop/iftop/sar (top equivalents for disk IO, network traffic, and sysstat counters)- glances/nmon/dstat/iptraf-ng (pretty monitoring CLI-GUI utils with more colors)- systemd-analyze blame (track down cause of slow boot times)- docker stats (htop equivalent for docker containers)- zpool iostat -v  1 (iotop equivalent for ZFS pools)
