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 ¶ added in v1.9.0
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 ¶
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]*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
