# Semantic conventions for hardware

**Status**: [Development][DocumentStatus]

This document describes instruments and attributes for common hardware level
metrics in OpenTelemetry. Consider the [general metric semantic conventions](/docs/specs/semconv/general/metrics.md#general-guidelines)
when creating instruments not explicitly defined in the specification.

Semantic conventions for hardware are defined as following:

* [Common Hardware Metrics](common.md): Semantic Conventions for *common* hardware metrics.
* [Physical Host Metrics](host.md): Semantic Conventions for *physical host* metrics.
* [Battery Metrics](battery.md): Semantic Conventions for *battery* metrics.
* [CPU Metrics](cpu.md): Semantic Conventions for *CPU* metrics.
* [Disk Controller Metrics](disk-controller.md): Semantic Conventions for *disk controller* metrics.
* [Enclosure Metrics](enclosure.md): Semantic Conventions for *enclosure* metrics.
* [Fan Metrics](fan.md): Semantic Conventions for *fan* metrics.
* [GPU Metrics](gpu.md): Semantic Conventions for *GPU* metrics.
* [Logical Disk Metrics](logical-disk.md): Semantic Conventions for *logical disk* metrics.
* [Memory Metrics](memory.md): Semantic Conventions for *memory* metrics.
* [Network Metrics](network.md): Semantic Conventions for *network* metrics.
* [Physical Disk Metrics](physical-disk.md): Semantic Conventions for *physical disk* metrics.
* [Power Supply Metrics](power-supply.md): Semantic Conventions for *power supply* metrics.
* [Tape Drive Metrics](tape-drive.md): Semantic Conventions for *tape drive* metrics.
* [Temperature Metrics](temperature.md): Semantic Conventions for *temperature* metrics.
* [Voltage Metrics](voltage.md): Semantic Conventions for *voltage* metrics.
