nmon (Nigel's Monitor) is a system performance monitoring tool for Linux/AIX that shows CPU, memory, disk, network, and process status together on one screen. In interactive mode, a single key toggles which items are displayed, and when run in data collection mode it records measurements at fixed intervals to a CSV file so they can be graphed and analyzed later. It is better suited than top or htop for getting an at-a-glance view of overall resources.
