Types

type Surfacer

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

Surfacer structures for writing onto a GCE instance's serial port. Keeps track of an output file which the incoming data is serialized onto (one entry per line).

func New

func New(ctx context.Context, config *configpb.SurfacerConf, opts *options.Options, l *logger.Logger) (*Surfacer, error)

New initializes a Surfacer for serializing data into a file (usually set as a GCE instance's serial port). This Surfacer does not utilize the Google cloud logger because it is unlikely to fail reportably after the call to New.

func (*Surfacer) Write

func (s *Surfacer) Write(ctx context.Context, em *metrics.EventMetrics)

Write queues the incoming data into a channel. This channel is watched by a goroutine that actually writes data to a file ((usually set as a GCE instance's serial port).
