Functions

func GetContainerMetric

func GetContainerMetric(metricsFetcher metric.MetricsFetcher, emitter metrics.MetricEmitter, podUID, containerName, metricName string, numaID int) (float64, error)

func GetPodMetric

func GetPodMetric(metricsFetcher metric.MetricsFetcher, emitter metrics.MetricEmitter, pod *v1.Pod, metricName string, numaID int) (float64, bool)

GetPodMetric returns the value of a pod-level metric. And the value of a pod-level metric is calculated by summing the metric values for all containers in that pod.

func GetSystemKswapdStealMetrics

func GetSystemKswapdStealMetrics(metricsFetcher metric.MetricsFetcher, emitter metrics.MetricEmitter) (metricutil.MetricData, error)

func GetWatermarkMetrics

func GetWatermarkMetrics(metricsFetcher metric.MetricsFetcher, emitter metrics.MetricEmitter, numaID int) (free, total, scaleFactor float64, err error)

GetWatermarkMetrics returns system-water mark related metrics (config) if numa node is specified, return config in this numa; otherwise return system-level config
