Types

type Metric

type Metric interface {
	Update() error
	GetMetricsName() string
	GetMetrics() map[string]string
}

Metric is an interface for metrics that test needs.

type MetricsCollector

type MetricsCollector struct {
	Metrics        []Metric   // metrics need update periodically
	OneTimeMetrics []Metric   // OneTimeMetrics just update one time
	Mu             sync.Mutex // mutex for protecting shared resources
}

MetricsCollector is a singleton struct for collecting metrics.

func GetMetricsCollector

func GetMetricsCollector() *MetricsCollector

GetMetricsCollector returns the singleton instance of MetricsCollector

func (*MetricsCollector) GetMetrics

func (m *MetricsCollector) GetMetrics() map[string]interface{}

GetMetrics returns the metrics from all metrics

func (*MetricsCollector) RegisterMetric

func (m *MetricsCollector) RegisterMetric(metric Metric)

RegisterMetric adds a metric to the MetricsCollector

func (*MetricsCollector) RegisterOneTimeMetric

func (m *MetricsCollector) RegisterOneTimeMetric(metric Metric)

RegisterOneTimeMetric adds a one-time metric to the MetricsCollector

func (*MetricsCollector) UpdateMetrics

func (m *MetricsCollector) UpdateMetrics()

UpdateMetrics periodically updates the metrics for all metrics

func (*MetricsCollector) UpdateOneTimeMetrics

func (m *MetricsCollector) UpdateOneTimeMetrics()

UpdateOneTimeMetrics periodically updates the one-time metrics for all metrics
