var NodePrePullImageList = sets.NewString(

NodePrePullImageList is a list of images used in node e2e test. These images will be prepulled before test running so that the image pulling won't fail in actual test.

func IsCgroup2UnifiedMode Uses

func IsCgroup2UnifiedMode() bool

IsCgroup2UnifiedMode returns whether we are running in cgroup v2 unified mode.

func PrePullAllImages Uses

func PrePullAllImages() error

PrePullAllImages pre-fetches all images tests depend on so that we don't fail in an actual test.

func SIGDescribe Uses

func SIGDescribe(text string, body func()) bool

SIGDescribe annotates the test with the SIG label.

type ResourceCollector Uses

type ResourceCollector struct {
    // contains filtered or unexported fields

ResourceCollector is a collector object which collects resource usage periodically from Cadvisor.

func NewResourceCollector Uses

func NewResourceCollector(interval time.Duration) *ResourceCollector

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

func (*ResourceCollector) GetBasicCPUStats Uses

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 Uses

func (r *ResourceCollector) GetCPUSummary() e2ekubelet.ContainersCPUSummary

GetCPUSummary gets CPU usage in percentile.

func (*ResourceCollector) GetLatest Uses

func (r *ResourceCollector) GetLatest() (e2ekubelet.ResourceUsagePerContainer, error)

GetLatest gets the latest resource usage from stats buffer.

func (*ResourceCollector) GetResourceTimeSeries Uses

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

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

func (*ResourceCollector) LogLatest Uses

func (r *ResourceCollector) LogLatest()

LogLatest logs the latest resource usage.

func (*ResourceCollector) Reset Uses

func (r *ResourceCollector) Reset()

Reset clears the stats buffer of resource collector.

func (*ResourceCollector) Start Uses

func (r *ResourceCollector) Start()

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

func (*ResourceCollector) Stop Uses

func (r *ResourceCollector) Stop()

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