The OpenTSDB client is a Java library that makes sending metrics and querying the OpenTSDB server simple. The HttpClientImpl class is used to push metrics or query the OpenTSDB server. The library uses the builder pattern to simplify the task of creating the JSON that is used by the client. Also it use the PoolingHttpClientConnectionManager to manager the http connection.

NOTE I only implements the send metrics interface. Please feel free to fork and implements for your needs.

Sending metrics is done by using the MetricBuilder. You simply add a metric, the tags associated with the metric, and the data points.

HttpClient client = new HttpClientImpl("http://localhost:8242");

MetricBuilder builder = MetricBuilder.getInstance();

builder.addMetric("metric1").setDataPoint(2, 30L)
		.addTag("tag1", "tab1value").addTag("tag2", "tab2value");

builder.addMetric("metric2").setDataPoint(2, 232.34)
		.addTag("tag3", "tab3value");

try {
	Response response = client.pushMetrics(builder,
			ExpectResponse.SUMMARY);
	System.out.println(response);
} catch (IOException e) {
	e.printStackTrace();
}
