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.
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.
