Types

type Aggregator added in v0.2.0 

type Aggregator string
const (
	AggregatorSum Aggregator = "sum"
	AggregatorAvg Aggregator = "avg"
)

type ContainerMetricFilter added in v0.2.0 

type ContainerMetricFilter func(pod *v1.Pod, container *v1.Container) bool

ContainerMetricFilter is used to filter out unnecessary metrics if this function returns false

type MetricData added in v0.3.0 

type MetricData struct {
	Value float64

	// Time may have different meanings in different scenarios
	// - for single metric: it represents the exact collecting time
	// - for aggregated metric: it represents the newest time among all metric items
	Time *time.Time
}

MetricData represents the standard response data for metric getter functions

type MetricStore 

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

MetricStore stores those metric data. Including: 1. raw data collected from agent.MetricsFetcher. 2. data calculated based on raw data.
