Golang Initialize Examples

Example #1

File: dropsonde.go Project: cloudfoundry/v3-cli-plugin

func initialize() {
	emitter := AutowiredEmitter()
	sender := metric_sender.NewMetricSender(emitter)
	batcher := metricbatcher.New(sender, defaultBatchInterval)
	metrics.Initialize(sender, batcher)
	logs.Initialize(log_sender.NewLogSender(AutowiredEmitter(), gosteno.NewLogger("dropsonde/logs")))
	envelopes.Initialize(envelope_sender.NewEnvelopeSender(emitter))
	go runtime_stats.NewRuntimeStats(DefaultEmitter, statsInterval).Run(nil)
	http.DefaultTransport = InstrumentedRoundTripper(http.DefaultTransport)
}

Example #2

File: main.go Project: kei-yamazaki/loggregator

func initializeMetrics(origin, destination string) (*metricbatcher.MetricBatcher, error) {
	err := setupDefaultEmitter(origin, destination)
	if err != nil {
		// Legacy holdover.  We would prefer to panic, rather than just throwing our metrics
		// away and pretending we're running fine, but for now, we just don't want to break
		// anything.
		dropsonde.DefaultEmitter = &dropsonde.NullEventEmitter{}
	}

	// Copied from dropsonde.initialize(), since we stopped using dropsonde.Initialize
	// but needed it to continue operating the same.
	sender := metric_sender.NewMetricSender(dropsonde.DefaultEmitter)
	batcher := metricbatcher.New(sender, defaultBatchInterval)
	metrics.Initialize(sender, batcher)
	logs.Initialize(log_sender.NewLogSender(dropsonde.DefaultEmitter, gosteno.NewLogger("dropsonde/logs")))
	envelopes.Initialize(envelope_sender.NewEnvelopeSender(dropsonde.DefaultEmitter))
	go runtime_stats.NewRuntimeStats(dropsonde.DefaultEmitter, statsInterval).Run(nil)
	http.DefaultTransport = dropsonde.InstrumentedRoundTripper(http.DefaultTransport)
	return batcher, err
}
