Hardware Attributes

Attributes for hardware.

Attribute	Type	Description	Examples	Stability
hw.id	string	An identifier for the hardware component, unique within the monitored host	win32battery_battery_testsysa33_1
hw.name	string	An easily-recognizable name for the hardware component	eth0
hw.parent	string	Unique identifier of the parent component (typically the hw.id attribute of the enclosure, or disk controller)	dellStorage_perc_0
hw.state	string	The current state of the component	ok; degraded; failed
hw.type	string	Type of the component [1]	battery; cpu; disk_controller

[1] hw.type: Describes the category of the hardware component for which hw.state is being reported. For example, hw.type=temperature along with hw.state=degraded would indicate that the temperature of the hardware component has been reported as degraded.

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.

Value	Description	Stability
degraded	Degraded
failed	Failed
ok	Ok
