sloptop

sloptop is a Rust TUI resource monitor for Linux.

Features

• CPU usage (total + per-core in detailed view)
• Memory and swap usage
• Disk usage per mounted disk
• Network throughput (RX/TX bytes per second) and totals
• Process count, uptime, host, and 1-minute load average
• Adjustable refresh interval and pause/resume
• Responsive layout for narrow terminals

Build

Prerequisites:

• Rust toolchain (rustc + cargo)

Build optimized binary:

cargo build --release

Binary path:

./target/release/sloptop

Run

Default refresh interval is 1000 ms:

cargo run -- --interval-ms 1000

Accepted interval range: 200..=5000 ms.

Keybindings

• q / Esc: quit
• p / Space: pause/resume sampling
• + / =: increase refresh interval by 200 ms
• -: decrease refresh interval by 200 ms
• d: toggle detailed view (shows per-core CPU list)

Notes

• Target platform is Linux.
• Network throughput is computed as a delta between consecutive samples.
• Disk and network metrics are system-wide aggregates.

Next steps

• Add top-process table with sorting/filtering
• Add historical sparklines and alert thresholds
• Extend platform-specific support and testing for macOS/Windows
