mactop Exporter — Grafana Dashboard

A comprehensive Grafana dashboard for Apple Silicon Macs, built on top of mactop — a Prometheus metrics exporter for Apple Silicon.

Features

48 panels across 9 sections:

Section	What you get
CPU	Per-core utilisation (P-cores / E-cores), cluster frequencies
GPU	40-cell grid utilisation, GPU frequency
Memory	RAM & swap usage, memory bandwidth
Power	Per-rail wattage (CPU · GPU · ANE · DRAM · System · Total)
Power Heatmap	Component intensity over time + watt-band distribution heatmap
Thermals	All 322 live SMC temperature sensors
Thermal Heatmap	Temperature distribution over time + top-60 sensor bar gauge
Disk & Network	Read/write throughput, network in/out
Timeline	Combined CPU · GPU · Power sparkline history

Requirements

• mactop running and scraping into Prometheus
• Grafana 10+ (tested on 12.4.0)

Installation

1. In Grafana, go to Dashboards → Import
2. Upload mactop_exporter_v1.json
3. Select your Prometheus datasource
4. Click Import

Known mactop quirks

• mactop_network_kbytes_per_sec actually reports bytes/sec (off by 1024×) — labelled accordingly in the dashboard
• VRM MD sensor (TVMD) is permanently stuck at 1 °C — this is an Apple SMC "not available" sentinel, not a real reading. All other 322 sensors report live data.
