Digger

Digger is the system monitor for Colony. Built with Rust and Iced, it provides real-time visibility into your machine's health - CPU, memory, network, disk, GPU, and processes - with a clean, themeable interface.

What it does

Digger gives you a live dashboard of everything happening on your system:

• System metrics - CPU (per-core and global), memory, swap, network I/O, disk I/O, temperatures, load averages
• GPU monitoring - see GPU support by platform
• Process management - List, filter, sort, group, and kill processes. Processes are classified into Apps, Background, and System categories
• Persistent history - All metrics are stored in a local SQLite database with configurable retention, exportable to CSV or JSON
• Alerting - Configurable CPU and memory thresholds with desktop notifications and an event log

Look & feel

Digger ships with 11 color themes across 4 families - Catppuccin, Gruvbox, Everblush, and Kanagawa - each combinable with 8 accent colors. Dark mode is detected automatically.

The UI is organized into four tabs:

Tab	Purpose
Overview	Gauges, charts, and sparklines for key metrics at a glance
Processes	Full process table with search, sorting, and grouping
History	Time-series charts with selectable ranges (1m → 24h)
Event Log	Alerts and anomalies with severity levels

Internationalization

Digger supports 50 languages with zero-cost static string tables compiled directly into the binary. Font selection adapts automatically to the active language.

GPU support by platform

• Linux: every GPU the kernel exposes under /sys/class/drm (AMD, Intel, NVIDIA), with utilization, VRAM, temperature and power where the driver reports them. NVIDIA cards are completed with nvidia-smi when it is installed.
• Windows: NVIDIA cards through nvidia-smi when it is installed. Otherwise (AMD, Intel) Digger falls back to WMI, which is coarser: utilization and memory are summed across all adapters, and temperature comes from LibreHardwareMonitor or OpenHardwareMonitor if one is running, else from the hottest system thermal zone.
• macOS: no GPU monitoring.

NVML is only used by builds made with --features gpu; the release binaries are built without it.

Running the binaries

The release binaries are not signed with an Apple or Microsoft certificate, so each OS warns on first launch. Colony installs them for you and checks the Project-Colony signature of every asset; the steps below are for running a binary downloaded by hand.

• Linux: chmod +x d1gg2r-linux && ./d1gg2r-linux

• macOS: make it executable and clear the download quarantine flag, then run it:

  chmod +x d1gg2r-macos
  xattr -d com.apple.quarantine d1gg2r-macos
  ./d1gg2r-macos

  xattr reports "No such xattr" when the file was not quarantined, which is fine. Use d1gg2r-macos-x86 on Intel Macs. If you skip the xattr step, macOS 15 and later block the first launch; allow it under System Settings > Privacy & Security > Open Anyway.

• Windows: SmartScreen shows "Windows protected your PC". Click More info, then Run anyway.

Code signing policy

Free code signing provided by SignPath.io, certificate by SignPath Foundation.

Windows builds are signed this way once the SignPath Foundation has accepted the project; until then they ship without Authenticode. Since v0.2.1, every release asset, on every platform, is signed with the Project-Colony organisation's ed25519 key, which Colony verifies before installing it.

Team roles and members:

• Committers and reviewers: MotherSphere
• Approvers: MotherSphere

Privacy

This program will not transfer any information to other networked systems unless specifically requested by the user or the person installing or operating it.

Digger has no telemetry and never connects to a server: the metrics it reads, and the history it keeps in a local SQLite database, stay on your machine.
