# 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:

```bash
cargo build --release
```

Binary path:

```bash
./target/release/sloptop
```

## Run

Default refresh interval is 1000 ms:

```bash
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
