Types

type Monitor

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

Monitor leverages juju's transient file mechanism to deliver one-off machine reboot notifications to interested entities.

func NewMonitor

func NewMonitor(transientDir string) *Monitor

NewMonitor returns a reboot monitor instance that stores its internal state into transientDir.

func (*Monitor) PurgeState

func (m *Monitor) PurgeState(tag names.Tag) error

PurgeState deletes any internal state maintained by the monitor for a particular entity.

func (*Monitor) Query

func (m *Monitor) Query(tag names.Tag) (bool, error)
