Functions ¶
func CapacityFromMachineInfo ¶ added in v1.3.0
func CapacityFromMachineInfo(info *cadvisorapi.MachineInfo) v1.ResourceList
func EphemeralStorageCapacityFromFsInfo ¶ added in v1.8.8
func EphemeralStorageCapacityFromFsInfo(info cadvisorapi2.FsInfo) v1.ResourceList
func UsingLegacyCadvisorStats ¶ added in v1.9.0
CRI integrations should get container metrics via CRI. Docker uses the built-in cadvisor to gather such metrics on Linux for historical reasons. cri-o relies on cadvisor as a temporary workaround. The code should be removed. Related issue: https://github.com/kubernetes/kubernetes/issues/51798 UsingLegacyCadvisorStats returns true if container stats are provided by cadvisor instead of through the CRI
Types ¶
type ImageFsInfoProvider ¶ added in v1.8.8
type ImageFsInfoProvider interface { // ImageFsInfoLabel returns the label cAdvisor should use to find the filesystem holding container images. ImageFsInfoLabel() (string, error) }
ImageFsInfoProvider informs cAdvisor how to find imagefs for container images.
func NewImageFsInfoProvider ¶ added in v1.8.8
func NewImageFsInfoProvider(runtime, runtimeEndpoint string) ImageFsInfoProvider
NewImageFsInfoProvider returns a provider for the specified runtime configuration.
type Interface ¶
type Interface interface { Start() error DockerContainer(name string, req *cadvisorapi.ContainerInfoRequest) (cadvisorapi.ContainerInfo, error) ContainerInfo(name string, req *cadvisorapi.ContainerInfoRequest) (*cadvisorapi.ContainerInfo, error) ContainerInfoV2(name string, options cadvisorapiv2.RequestOptions) (map[string]cadvisorapiv2.ContainerInfo, error) SubcontainerInfo(name string, req *cadvisorapi.ContainerInfoRequest) (map[string]*cadvisorapi.ContainerInfo, error) MachineInfo() (*cadvisorapi.MachineInfo, error) VersionInfo() (*cadvisorapi.VersionInfo, error) // Returns usage information about the filesystem holding container images. ImagesFsInfo() (cadvisorapiv2.FsInfo, error) // Returns usage information about the root filesystem. RootFsInfo() (cadvisorapiv2.FsInfo, error) // Get events streamed through passedChannel that fit the request. WatchEvents(request *events.Request) (*events.EventChannel, error) // HasDedicatedImageFs returns true iff a dedicated image filesystem exists for storing images. HasDedicatedImageFs() (bool, error) // GetFsInfoByFsUUID returns the stats of the filesystem with the specified // uuid. GetFsInfoByFsUUID(uuid string) (cadvisorapiv2.FsInfo, error) }
Interface is an abstract interface for testability. It abstracts the interface to cAdvisor.
