HttpTransport httpTransport = new HttpTransport.Builder().withApiKey(apiKey).build();
datadogReporter = DatadogReporter.forRegistry(registry).withTransport(httpTransport)
.withExpansions(EnumSet.of(DatadogReporter.Expansion.COUNT)).build();
datadogReporter.start(1, TimeUnit.MINUTES);

registry.counter("if.you.really.cant.do.that.by.yourself.you.really.should.reconsider.yourself.as.a.develeoper").inc()
