Functions ¶

func ProcessorCount ¶

func ProcessorCount() int

runtime.NumCPU() will only return the information for a single Processor Group. Since a single group can only hold 64 logical processors, this means when there are more they will be divided into multiple groups. For the above reason, procGetActiveProcessorCount is used to get the cpu count for all processor groups of the windows node. more notes for this issue: same issue in moby: https://github.com/moby/moby/issues/38935#issuecomment-744638345 solution in hcsshim: https://github.com/microsoft/hcsshim/blob/master/internal/processorinfo/processor_count.go

Types ¶

type Client ¶

type Client interface {
	WinContainerInfos() (map[string]cadvisorapiv2.ContainerInfo, error)
	WinMachineInfo() (*cadvisorapi.MachineInfo, error)
	WinVersionInfo() (*cadvisorapi.VersionInfo, error)
	GetDirFsInfo(path string) (cadvisorapiv2.FsInfo, error)
}

Client is an interface that is used to get stats information.

func NewPerfCounterClient ¶

func NewPerfCounterClient() (Client, error)

NewPerfCounterClient creates a client using perf counters

type MemoryStatusEx ¶

type MemoryStatusEx struct {
	Length               uint32
	MemoryLoad           uint32
	TotalPhys            uint64
	AvailPhys            uint64
	TotalPageFile        uint64
	AvailPageFile        uint64
	TotalVirtual         uint64
	AvailVirtual         uint64
	AvailExtendedVirtual uint64
}

MemoryStatusEx is the same as Windows structure MEMORYSTATUSEX https://msdn.microsoft.com/en-us/library/windows/desktop/aa366770(v=vs.85).aspx

type OSInfo ¶

type OSInfo struct {
	BuildNumber, ProductName        string
	MajorVersion, MinorVersion, UBR uint64
}

OSInfo is a convenience class for retrieving Windows OS information

func GetOSInfo ¶

func GetOSInfo() (*OSInfo, error)

GetOSInfo reads Windows version information from the registry

func (*OSInfo) GetBuild ¶

func (o *OSInfo) GetBuild() string

GetBuild returns OS version upto build number

func (*OSInfo) GetPatchVersion ¶

func (o *OSInfo) GetPatchVersion() string

GetPatchVersion returns full OS version with patch

type StatsClient ¶

type StatsClient struct {
	// contains filtered or unexported fields
}

StatsClient is a client that implements the Client interface

func (*StatsClient) GetDirFsInfo ¶

func (c *StatsClient) GetDirFsInfo(path string) (cadvisorapiv2.FsInfo, error)

GetDirFsInfo returns filesystem capacity and usage information.

func (*StatsClient) WinContainerInfos ¶

func (c *StatsClient) WinContainerInfos() (map[string]cadvisorapiv2.ContainerInfo, error)

WinContainerInfos returns a map of container infos. The map contains node and pod level stats. Analogous to cadvisor GetContainerInfoV2 method.

func (*StatsClient) WinMachineInfo ¶

func (c *StatsClient) WinMachineInfo() (*cadvisorapi.MachineInfo, error)

WinMachineInfo returns a cadvisorapi.MachineInfo with details about the node machine. Analogous to cadvisor MachineInfo method.

func (*StatsClient) WinVersionInfo ¶

func (c *StatsClient) WinVersionInfo() (*cadvisorapi.VersionInfo, error)

WinVersionInfo returns a cadvisorapi.VersionInfo with version info of the kernel and docker runtime. Analogous to cadvisor VersionInfo method.
