Metric: hw.power_supply.utilization

This metric is recommended.

Name	Instrument Type	Unit (UCUM)	Description	Stability	Entity Associations
hw.power_supply.utilization	Gauge	1	Utilization of the power supply as a fraction of its maximum output.

Attributes:

Key	Stability	Requirement Level	Value Type	Description	Example Values

Metric: hw.power_supply.usage

This metric is recommended.

Name	Instrument Type	Unit (UCUM)	Description	Stability	Entity Associations
hw.power_supply.usage	UpDownCounter	W	Current power output of the power supply.

Attributes:

Key	Stability	Requirement Level	Value Type	Description	Example Values
hw.id		Required	string	An identifier for the hardware component, unique within the monitored host	win32battery_battery_testsysa33_1
hw.model		Recommended	string	Descriptive model name of the hardware component	PERC H740P; Intel(R) Core(TM) i7-10700K; Dell XPS 15 Battery

Metric: hw.status (Power Supply)

This metric is recommended.

Name	Instrument Type	Unit (UCUM)	Description	Stability	Entity Associations
hw.status	UpDownCounter	1	Operational status: 1 (true) or 0 (false) for each of the possible states. [1]

[1]: hw.status is currently specified as an UpDownCounter but would ideally be represented using a StateSet as defined in OpenMetrics. This semantic convention will be updated once StateSet is specified in OpenTelemetry. This planned change is not expected to have any consequence on the way users query their timeseries backend to retrieve the values of hw.status over time.

Attributes:

Key	Stability	Requirement Level	Value Type	Description	Example Values
hw.id		Required	string	An identifier for the hardware component, unique within the monitored host	win32battery_battery_testsysa33_1
hw.state		Required	string	The current state of the component [1]	ok; degraded; failed
hw.type		Required	string	Type of the component [2]	power_supply
hw.model		Recommended	string	Descriptive model name of the hardware component	PERC H740P; Intel(R) Core(TM) i7-10700K; Dell XPS 15 Battery
hw.name		Recommended	string	An easily-recognizable name for the hardware component	eth0
hw.parent		Recommended	string	Unique identifier of the parent component (typically the hw.id attribute of the enclosure, or disk controller)	dellStorage_perc_0
hw.serial_number		Recommended	string	Serial number of the hardware component	CNFCP0123456789
hw.vendor		Recommended	string	Vendor name of the hardware component	Dell; HP; Intel; AMD; LSI; Lenovo

[1] hw.state: MUST be set to one of the following values:

• ok: The power supply is operating normally.
• degraded: The power supply is operating with reduced functionality or performance.
• failed: The power supply has failed and is not operational.

[2] hw.type: MUST be set to power_supply.

hw.state has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.
