Constants ¶

const (
	TimeSeriesTag = "[Result:TimeSeries]"
	TimeSeriesEnd = "[Finish:TimeSeries]"
)

Variables ¶

var ImageRegistry = map[int]string{
	// contains filtered or unexported fields
}

var NoPullImageRegistry = map[int]string{
	// contains filtered or unexported fields
}

These are used by tests that explicitly test the ability to pull images

Functions ¶

func PrePullAllImages ¶

func PrePullAllImages() error

Pre-fetch all images tests depend on so that we don't fail in an actual test

Types ¶

type ConformanceContainer ¶

type ConformanceContainer struct {
	Container        api.Container
	RestartPolicy    api.RestartPolicy
	Volumes          []api.Volume
	ImagePullSecrets []string

	PodClient *framework.PodClient

	PodSecurityContext *api.PodSecurityContext
	// contains filtered or unexported fields
}

One pod one container TODO: This should be migrated to the e2e framework.

type ContainerState ¶

type ContainerState int

const (
	ContainerStateWaiting ContainerState = iota
	ContainerStateRunning
	ContainerStateTerminated
	ContainerStateUnknown
)

func GetContainerState ¶

func GetContainerState(state api.ContainerState) ContainerState

type NodeTimeSeries ¶

type NodeTimeSeries struct {
	// value in OperationData is an array of timestamps
	OperationData map[string][]int64         `json:"op_series,omitempty"`
	ResourceData  map[string]*ResourceSeries `json:"resource_series,omitempty"`
	Labels        map[string]string          `json:"labels"`
	Version       string                     `json:"version"`
}

type ResourceCollector ¶

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

func NewResourceCollector ¶

func NewResourceCollector(interval time.Duration) *ResourceCollector

NewResourceCollector creates a resource collector object which collects resource usage periodically from Cadvisor

func (*ResourceCollector) GetBasicCPUStats ¶

func (r *ResourceCollector) GetBasicCPUStats(containerName string) map[float64]float64

GetBasicCPUStats returns the percentiles the cpu usage in cores for containerName. This method examines all data currently in the buffer.

func (*ResourceCollector) GetCPUSummary ¶

func (r *ResourceCollector) GetCPUSummary() framework.ContainersCPUSummary

GetCPUSummary gets CPU usage in percentile.

func (*ResourceCollector) GetLatest ¶

func (r *ResourceCollector) GetLatest() (framework.ResourceUsagePerContainer, error)

GetLatest gets the latest resource usage from stats buffer.

func (*ResourceCollector) GetResourceTimeSeries ¶

func (r *ResourceCollector) GetResourceTimeSeries() map[string]*ResourceSeries

GetResourceSeriesWithLabels gets the time series of resource usage of each container.

func (*ResourceCollector) LogLatest ¶

func (r *ResourceCollector) LogLatest()

LogLatest logs the latest resource usage.

func (*ResourceCollector) Reset ¶

func (r *ResourceCollector) Reset()

Reset clears the stats buffer of resource collector.

func (*ResourceCollector) Start ¶

func (r *ResourceCollector) Start()

Start starts resource collector and connects to the standalone Cadvisor pod then repeatedly runs collectStats.

func (*ResourceCollector) Stop ¶

func (r *ResourceCollector) Stop()

Stop stops resource collector collecting stats. It does not clear the buffer

type ResourceSeries ¶

type ResourceSeries struct {
	Timestamp            []int64           `json:"ts"`
	CPUUsageInMilliCores []int64           `json:"cpu"`
	MemoryRSSInMegaBytes []int64           `json:"memory"`
	Units                map[string]string `json:"unit"`
}

Time series of resource usage
