Types

type Host

type Host struct {
	LastUpdated time.Time
	Name        string
	Failures    int
	State       bool
}

func (*Host) UpdateStatus

func (h *Host) UpdateStatus(reachable bool)

UpdateStatus updates the status of the host

type Registry

type Registry struct {
	Logger *slog.Logger
	// contains filtered or unexported fields
}

func (*Registry) Cleanup

func (r *Registry) Cleanup()

func (*Registry) Collect

func (r *Registry) Collect(ch chan<- prometheus.Metric)

func (*Registry) Describe

func (r *Registry) Describe(ch chan<- *prometheus.Desc)

func (*Registry) HostState
