func (CPUDetails) Sockets 

func (d CPUDetails) Sockets() cpuset.CPUSet

Sockets returns all of the socket IDs associated with the CPUs in this CPUDetails.

func (CPUDetails) SocketsInNUMANodes 

func (d CPUDetails) SocketsInNUMANodes(ids ...int) cpuset.CPUSet

SocketsInNUMANodes returns all of the logical Socket IDs associated with the given NUMANode IDs in this CPUDetails.

type CPUInfo 

type CPUInfo struct {
	NUMANodeID int
	SocketID   int
	CoreID     int
}

CPUInfo contains the NUMA, socket, and core IDs associated with a CPU.

type CPUTopology 

type CPUTopology struct {
	NumCPUs      int
	NumCores     int
	NumSockets   int
	NumNUMANodes int
	CPUDetails   CPUDetails
}

CPUTopology contains details of node cpu, where : CPU - logical CPU, cadvisor - thread Core - physical CPU, cadvisor - Core Socket - socket, cadvisor - Socket NUMA Node - NUMA cell, cadvisor - Node

func Discover 

func Discover(machineInfo *cadvisorapi.MachineInfo) (*CPUTopology, error)

Discover returns CPUTopology based on cadvisor node info

func (*CPUTopology) CPUsPerCore 

func (topo *CPUTopology) CPUsPerCore() int

CPUsPerCore returns the number of logical CPUs are associated with each core.

func (*CPUTopology) CPUsPerSocket 

func (topo *CPUTopology) CPUsPerSocket() int

CPUsPerSocket returns the number of logical CPUs are associated with each socket.

type NUMANodeInfo 

type NUMANodeInfo map[int]cpuset.CPUSet

NUMANodeInfo is a map from NUMANode ID to a list of CPU IDs associated with that NUMANode.
