type StatsProvider ¶
type StatsProvider struct {
// contains filtered or unexported fields
}
StatsProvider provides the stats of the node and the pod-managed containers.
func NewCRIStatsProvider ¶
func NewCRIStatsProvider( cadvisor cadvisor.Interface, resourceAnalyzer stats.ResourceAnalyzer, podManager kubepod.Manager, runtimeCache kubecontainer.RuntimeCache, runtimeService internalapi.RuntimeService, imageService internalapi.ImageManagerService, ) *StatsProvider
NewCRIStatsProvider returns a StatsProvider that provides the node stats from cAdvisor and the container stats from CRI.
func NewCadvisorStatsProvider ¶
func NewCadvisorStatsProvider( cadvisor cadvisor.Interface, resourceAnalyzer stats.ResourceAnalyzer, podManager kubepod.Manager, runtimeCache kubecontainer.RuntimeCache, imageService kubecontainer.ImageService, ) *StatsProvider
NewCadvisorStatsProvider returns a containerStatsProvider that provides both the node and the container stats from cAdvisor.
func (*StatsProvider) GetCgroupStats ¶
func (p *StatsProvider) GetCgroupStats(cgroupName string, updateStats bool) (*statsapi.ContainerStats, *statsapi.NetworkStats, error)
GetCgroupStats returns the stats of the cgroup with the cgroupName. Note that this function doesn't generate filesystem stats.
