Functions

func StartDiskUsageMonitor

func StartDiskUsageMonitor(s Setter, rootDir string, interval time.Duration)

StartDiskUsageMonitor retrieves the total disk usage of the provided directory at each provided time interval, and set it as a prometheus metric.

Types

type Setter

type Setter interface {
	Set(m float64)
}

Setter is an interface for prometheus metrics to improve unit-testability.
