Go Attributes

This document defines Go related attributes.

Attributes:

Key	Stability	Value Type	Description	Example Values
go.cpu.detailed_state		string	The detailed state of the CPU. [1]	gc/pause; gc/mark/assist
go.cpu.state		string	The state of the CPU.	user; gc
go.memory.detailed_type		string	The detailed type of memory. [2]	heap/objects; heap/free
go.memory.type		string	The type of memory.	other; stack

[1] go.cpu.detailed_state: Value SHOULD match the specific CPU class reported by the Go runtime under /cpu/classes/.... The list of possible values is subject to change with the Go version used.

[2] go.memory.detailed_type: Value SHOULD match the specific memory class reported by the Go runtime under /memory/classes/.... The list of possible values is subject to change with the Go version used.

go.cpu.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
gc	CPU time spent performing garbage collection tasks.
idle	Available CPU time not spent executing any Go or Go runtime code.
scavenge	CPU time spent returning unused memory to the underlying platform.
user	CPU time spent running user Go code.

go.memory.type 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
other	Memory used by the Go runtime, excluding other categories of memory usage described in this enumeration.
stack	Memory allocated from the heap that is reserved for stack space, whether or not it is currently in-use. [3]
