📝 WalkthroughWalkthroughThe Node Exporter Metrics reference documents macOS support for the ChangesmacOS Node Exporter collector documentation
Estimated code review effort: 1 (Trivial) | ~3 minutes Merge Risk: 🔵 Low · up to The documentation adds macOS collector coverage, but the thermal_zone scrape-interval key does not match the runtime key, so users may configure an override that is ignored and fall back to the global interval. The PR is mergeable with owner awareness and a follow-up to align the spelling. Suggested reviewers: 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 115-124: Update the macOS metric documentation around
node_thermal_temperature_celsius to state that it is reported only on
ARM64/Apple Silicon; clarify that Intel macOS does not produce samples while
preserving the existing descriptions of the CPU metrics.

…d thermal_zone
Document macOS support for the stat and thermal_zone collectors added to
the node exporter metrics input in fluent-bit 5a1300632 and 8556d0368.
- Update the macOS default for the metrics option to include stat and
thermal_zone, matching NE_DEFAULT_ENABLED_METRICS
- Add stat and thermal_zone to the macOS data source sentence in the same
description: stat reads sysctl, thermal_zone reads IOKit
- Mark the stat collector as available on macOS and note that only boot
time is exposed there, read from the kern.boottime sysctl, while forks
and interruptions remain Linux-only
- Mark the thermal_zone collector as available on macOS and link it to a
new macOS thermal metrics section
- Add a macOS thermal metrics section listing the four metrics exposed
there, since macOS has no /sys/class/thermal equivalent and the metric
set differs from Linux
- Note that the three cpu_ metrics only appear once the operating system
records a CPU power limit, that they are created individually so some
can appear before others, and that the ratios are fractions between 0
and 1 rather than percentages
- Note that a sensor without a product name is labeled Unknown #N
- Re-pad the collectors table so the pipes stay aligned for MD060 after
the wider Version column
- Note ARM64-only macOS thermal sensors

In `@pipeline/inputs/node-exporter-metrics.md`:
- Line 67: The thermal-zone scrape interval uses inconsistent configuration
keys. Align the runtime lookup and configuration map/documentation to one
spelling, preferably the existing thermal_zone form, so
collector.thermal_zone.scrape_interval overrides are honored.
