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.

Functions ¶

func IsCgroup2UnifiedMode ¶

func IsCgroup2UnifiedMode() bool

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

func PrePullAllImages ¶

func PrePullAllImages() error

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

func SIGDescribe ¶

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

SIGDescribe annotates the test with the SIG label.

Types ¶

type ResourceCollector ¶

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

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

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() e2ekubelet.ContainersCPUSummary

GetCPUSummary gets CPU usage in percentile.

func (*ResourceCollector) GetLatest ¶

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

GetLatest gets the latest resource usage from stats buffer.

func (*ResourceCollector) GetResourceTimeSeries ¶

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

GetResourceTimeSeries 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
