Updated: 28 September 2026 · Applies to: Ubuntu 24.04, Debian 12, AlmaLinux 9 and Rocky Linux 9
Scout_Realtime is no longer developed: its project was archived in 2022, and it needs an old Ruby version. Use one of these maintained tools on Ubuntu 24.04, Debian 12, AlmaLinux 9 and Rocky Linux 9 instead.
In the terminal: htop or btop
dnf install epel-release && dnf install htop btop # AlmaLinux / Rocky apt install htop btop # Ubuntu / Debian
btop shows live graphs for CPU, memory, disks, network and the top processes, much like Scout_Realtime did in the browser.
In the browser: Cockpit (AlmaLinux / Rocky)
dnf install cockpit systemctl enable --now cockpit.socket
Open https://SERVER-IP:9090 and log in with a system user. Cockpit shows CPU, memory, disk and network graphs, services, logs and a terminal.
In the browser: Netdata
Netdata collects hundreds of metrics per second with ready-made dashboards and alerts. See "Monitoring Performance Of CentOS 8/7 Server Using Netdata".
Note: Web dashboards should not be open to everyone. Allow their ports only from your own IP, or reach them through an SSH tunnel.
