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.
