Rainbarf is a small, Perl-based command-line utility that generates resource usage charts (CPU, RAM, battery) in a compact bar-glyph format, designed to display within tmux or GNU screen status lines for a sleek system monitor. Use load average metric instead of CPU utilization. You might want to set the --max threshold since this is an absolute value and has varying ranges on different systems. Disabled by default. Configurable via environment variable or config file. Simple CLI usage and easily integrated into devops or system monitoring setups. Designed to render within tmux or GNU screen status bars.
