Types

type LogTailer

type LogTailer interface {
	// Logs returns the channel through which the LogTailer returns Juju logs.
	// It will be closed when the tailer stops.
	Logs() <-chan *corelogger.LogRecord

	// Dying returns a channel which will be closed as the LogTailer stops.
	Dying() <-chan struct{}

	// Kill implements worker.Kill.
	Kill()

	// Wait implements worker.Wait.
	Wait() error
}

LogTailer allows for retrieval of Juju's logs. It first returns any matching already recorded logs and then waits for additional matching logs as they appear.
