Overview ¶
Package stats handles exporting Kubelet and container stats. NOTE: We intend to move this functionality into a standalone pod, so this package should be very loosely coupled to the rest of the Kubelet.

Functions ¶
func CreateHandlers ¶
func CreateHandlers(rootPath string, provider StatsProvider, summaryProvider SummaryProvider) *restful.WebService
Types ¶
type ByCreationTime ¶
type ByCreationTime []containerInfoWithCgroup
ByCreationTime implements sort.Interface for []containerInfoWithCgroup based on the cinfo.Spec.CreationTime field.
func (ByCreationTime) Len ¶
func (a ByCreationTime) Len() int
func (ByCreationTime) Less ¶
func (a ByCreationTime) Less(i, j int) bool
func (ByCreationTime) Swap ¶
func (a ByCreationTime) Swap(i, j int)
type Cache ¶
Map to PodVolumeStats pointers since the addresses for map values are not constant and can cause pain if we need ever to get a pointer to one of the values (e.g. you can't)
type PodVolumeStats ¶
type PodVolumeStats struct {
Volumes []stats.VolumeStats
}
PodVolumeStats encapsulates all VolumeStats for a pod
type ResourceAnalyzer ¶
type ResourceAnalyzer interface {
Start()
SummaryProvider
// contains filtered or unexported methods
}
ResourceAnalyzer provides statistics on node resource consumption
func NewResourceAnalyzer ¶
func NewResourceAnalyzer(statsProvider StatsProvider, calVolumeFrequency time.Duration, runtime container.Runtime) ResourceAnalyzer
NewResourceAnalyzer returns a new ResourceAnalyzer
type StatsProvider ¶
type StatsProvider interface {
GetContainerInfo(podFullName string, uid types.UID, containerName string, req *cadvisorapi.ContainerInfoRequest) (*cadvisorapi.ContainerInfo, error)
GetContainerInfoV2(name string, options cadvisorapiv2.RequestOptions) (map[string]cadvisorapiv2.ContainerInfo, error)
GetRawContainerInfo(containerName string, req *cadvisorapi.ContainerInfoRequest, subcontainers bool) (map[string]*cadvisorapi.ContainerInfo, error)
GetPodByName(namespace, name string) (*v1.Pod, bool)
GetNode() (*v1.Node, error)
GetNodeConfig() cm.NodeConfig
ImagesFsInfo() (cadvisorapiv2.FsInfo, error)
RootFsInfo() (cadvisorapiv2.FsInfo, error)
ListVolumesForPod(podUID types.UID) (map[string]volume.Volume, bool)
GetPods() []*v1.Pod
}
Host methods required by stats handlers.
type StatsRequest ¶
type StatsRequest struct {
// The name of the container for which to request stats.
// Default: /
// +optional
ContainerName string `json:"containerName,omitempty"`
// Max number of stats to return.
// If start and end time are specified this limit is ignored.
// Default: 60
// +optional
NumStats int `json:"num_stats,omitempty"`
// Start time for which to query information.
// If omitted, the beginning of time is assumed.
// +optional
Start time.Time `json:"start,omitempty"`
// End time for which to query information.
// If omitted, current time is assumed.
// +optional
End time.Time `json:"end,omitempty"`
// Whether to also include information from subcontainers.
// Default: false.
// +optional
Subcontainers bool `json:"subcontainers,omitempty"`
}
type SummaryProvider ¶
type SummaryProvider interface {
// Get provides a new Summary using the latest results from cadvisor
Get() (*stats.Summary, error)
}
func NewSummaryProvider ¶
func NewSummaryProvider(statsProvider StatsProvider, fsResourceAnalyzer fsResourceAnalyzerInterface, cruntime container.Runtime) SummaryProvider
NewSummaryProvider returns a new SummaryProvider
