Functions ¶

func NewMetricsLogger ¶

func NewMetricsLogger(url string, p time.Duration, restrict map[string]bool, log *log.Logger) *monitor

NewMetricsLogger periodically (every p duration) fetches prometheus metrics from the given url and logs them to the given logger. If restrict is provided, only the metrics specified will be logged.

func NewNodeOomDetector ¶

func NewNodeOomDetector(nodeMetricsUrl string, log *log.Logger) *oomDetector

Types ¶

type MetricsMonitor ¶

type MetricsMonitor interface {
	// Go starts monitoring of metrics using the given context.
	// Typically Go would never return until context cancellation and hence should be run in a goroutine.
	Go(ctx context.Context)
}
