System Monitoring
Distro support
Monitoring commands are identical on both families — top, htop, ss,
vmstat, iostat, free, uptime, ps, sar behave the same. The only
differences are how the tools are installed and a couple of package names. Body
uses Debian/Ubuntu; the RHEL family (Fedora, RHEL, CentOS Stream, Rocky,
Alma, Oracle) equivalents are in the matrix.

dnf install htop sysstat |
| sysstat package | sysstat |
sysstat (enable sysstat.service) |
| Process/socket/mem tools | ps, ss, free, vmstat |
identical |
| Service health | systemctl status / journalctl |
identical |
