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

func PrePullAllImages() error

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

func SIGDescribe

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

Types

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

GetCPUSummary gets CPU usage in percentile.

func (*ResourceCollector) GetLatest

GetLatest gets the latest resource usage from stats buffer.

func (*ResourceCollector) GetResourceTimeSeries

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