Types

type CPUDetails

type CPUDetails map[int]CPUInfo

CPUDetails is a map from CPU ID to Core ID and Socket ID.

func (CPUDetails) CPUs

func (d CPUDetails) CPUs() cpuset.CPUSet

CPUs returns all of the logical CPU IDs in this CPUDetails.

func (CPUDetails) CPUsInCore

func (d CPUDetails) CPUsInCore(id int) cpuset.CPUSet

CPUsInCore returns all of the logical CPU IDs associated with the given core ID in this CPUDetails.

func (CPUDetails) CPUsInSocket

func (d CPUDetails) CPUsInSocket(id int) cpuset.CPUSet

CPUsInSocket returns all of the logical CPU IDs associated with the given socket ID in this CPUDetails.

func (CPUDetails) Cores

func (d CPUDetails) Cores() cpuset.CPUSet

Cores returns all of the core IDs associated with the CPUs in this CPUDetails.

func (CPUDetails) CoresInSocket

func (d CPUDetails) CoresInSocket(id int) cpuset.CPUSet

CoresInSocket returns all of the core IDs associated with the given socket ID in this CPUDetails.

func (CPUDetails) KeepOnly

func (d CPUDetails) KeepOnly(cpus cpuset.CPUSet) CPUDetails

KeepOnly returns a new CPUDetails object with only the supplied cpus.

func (CPUDetails) Sockets

func (d CPUDetails) Sockets() cpuset.CPUSet

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

type CPUInfo

type CPUInfo struct {
	SocketID int
	CoreID   int
}

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

type CPUTopology

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

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