NodeImageWhiteList 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 PrePullAllImages added in v1.3.0 

func PrePullAllImages() error

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

type ResourceCollector added in v1.4.2 

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

func NewResourceCollector added in v1.4.2 

func NewResourceCollector(interval time.Duration) *ResourceCollector

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

func (*ResourceCollector) GetBasicCPUStats added in v1.4.2 

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 added in v1.4.2 

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

GetCPUSummary gets CPU usage in percentile.

func (*ResourceCollector) GetLatest added in v1.4.2 

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

GetLatest gets the latest resource usage from stats buffer.

func (*ResourceCollector) GetResourceTimeSeries added in v1.4.2 

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

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

func (*ResourceCollector) LogLatest added in v1.4.2 

func (r *ResourceCollector) LogLatest()

LogLatest logs the latest resource usage.

func (*ResourceCollector) Reset added in v1.4.2 

func (r *ResourceCollector) Reset()

Reset clears the stats buffer of resource collector.

func (*ResourceCollector) Start added in v1.4.2 

func (r *ResourceCollector) Start()

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

func (*ResourceCollector) Stop added in v1.4.2 

func (r *ResourceCollector) Stop()

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