## Project history and usage

macmon is a Rust system-monitoring CLI and TUI for Apple Silicon Macs. Its README emphasizes sudoless access to live power, temperature, CPU, GPU, ANE, memory, and fan metrics.

### Project history

The official repository was created in June 2024. The README states that the project was motivated by a need to observe Apple Silicon power consumption while testing local LLM models, without relying on `powermetrics` workflows that require root privileges.

macmon expanded beyond a simple terminal display into JSON output, an HTTP metrics server, Prometheus-format metrics, a Grafana example, launchd service installation for `macmon serve`, and a Rust library API for embedding the sampler in other programs.

### Adoption history

The README documents installation through Homebrew, MacPorts, Cargo, and Nix, and the batch input also records Homebrew, MacPorts, and Nix packages. Repository metadata captured during this run showed more than one thousand GitHub stars within roughly two years of creation, suggesting fast adoption among Apple Silicon power users and monitoring hobbyists.

### How it is used

Interactive use runs the TUI at a configurable interval. Scripted use centers on `macmon pipe` for JSON samples, while monitoring-stack use centers on `macmon serve`, which exposes `/json` and `/metrics` endpoints and can install a launchd agent at `~/Library/LaunchAgents/com.macmon.plist`.

### Why package nerds care

macmon is notable because Apple Silicon telemetry is useful to developers running local AI models, compilers, benchmarks, and long-lived services, but official user-facing tools expose only part of that picture. A package-manager-installable TUI plus Prometheus endpoint makes Mac hardware metrics fit into Unix-style pipelines and observability stacks.

### Timeline

- 2024: Official GitHub repository created.
- 2024: 0.4.x releases published late in the year.
- 2025: 0.6.x releases added to the release stream.
- 2026: 0.7.x releases published, with docs covering HTTP metrics and library use.

### Related projects

- The README explicitly compares the motivation with `asitop` and `powermetrics`, and documents integration with Prometheus and Grafana.
