Dgxtop

dgxtop v0.2.0 — Time-Series Charts, Stats & Responsive UI

A major feature release with historical statistics, line charts, load averages, responsive layout, and device selection.

New Features

Time-Series Charts & Historical Stats

• Line charts for GPU (utilization, memory, temperature), Disk I/O (read/write), and Network (RX/TX) using Braille markers
• 1/6/12/24h statistics — average and max for CPU, Memory, GPU; avg R/W throughput for Disk; cumulative ↓/↑ bytes for Network
• Minute-resolution aggregation — TimeWindowAggregator stores up to 24h of data in memory-efficient minute buckets (~28KB per metric)
• Progressive display — stats windows only appear after enough time has elapsed (no duplicate numbers on fresh start)

CPU Enhancements

• Load average (1/5/15 min) from /proc/loadavg with color-coded thresholds
• Task count (running/total) displayed in CPU info line
• htop-style per-core view (e key) — auto column count based on core count (2/4/8 cols)
• CPU & Memory 1/6/12/24h avg/max stats

Device Selection & Sorting

• Network interface selection (n/N) — cycle interfaces, chart/stats follow selection
• Disk device selection (d/D) — cycle devices, chart/stats follow selection
• Network sorted by: active (up) first → type priority (Ethernet > WiFi > IB) → throughput descending
• Disk sorted by: total throughput descending (busiest first)
• Case-insensitive interface detection — fixes mixed-case names like enP7s7
• --net-max N CLI flag to control max visible interfaces/disks (default: 3)

Responsive Layout

• Auto-adapts to terminal height — proportionally allocates space to CPU+Memory, IO, and Process panels
• Adaptive IO panels — chart and stats conditionally shown based on available height
• Compact stats format — x/x/x/x single-line format fits all 4 time windows without truncation

Keyboard Shortcuts

| Key | Action |
|-----|--------|
| e | Toggle per-core CPU view (htop-style) |
| n / N | Cycle network interface |
| d / D | Cycle disk device |
| + / - | Faster / slower refresh |
