Examples with StatsDSink org.apache.hadoop.metrics2.sink.StatsDSink used on opensource projects

Example 1 with StatsDSink

use of org.apache.hadoop.metrics2.sink.StatsDSink in project hadoop by apache.

the class TestStatsDMetrics method testPutMetrics.

@Test(timeout = 3000)
public void testPutMetrics() throws IOException, InterruptedException {
    final StatsDSink sink = new StatsDSink();
    List<MetricsTag> tags = new ArrayList<MetricsTag>();
    tags.add(new MetricsTag(MsInfo.Hostname, "host"));
    tags.add(new MetricsTag(MsInfo.Context, "jvm"));
    tags.add(new MetricsTag(MsInfo.ProcessName, "process"));
    Set<AbstractMetric> metrics = new HashSet<AbstractMetric>();
    metrics.add(makeMetric("foo1", 1.25, MetricType.COUNTER));
    metrics.add(makeMetric("foo2", 2.25, MetricType.GAUGE));
    final MetricsRecord record = new MetricsRecordImpl(MsInfo.Context, (long) 10000, tags, metrics);
    try (DatagramSocket sock = new DatagramSocket()) {
        sock.setReceiveBufferSize(8192);
        final StatsDSink.StatsD mockStatsD = new StatsD(sock.getLocalAddress().getHostName(), sock.getLocalPort());
        Whitebox.setInternalState(sink, "statsd", mockStatsD);
        final DatagramPacket p = new DatagramPacket(new byte[8192], 8192);
        sink.putMetrics(record);
        sock.receive(p);
        String result = new String(p.getData(), 0, p.getLength(), Charset.forName("UTF-8"));
        assertTrue("Received data did not match data sent", result.equals("host.process.jvm.Context.foo1:1.25|c") || result.equals("host.process.jvm.Context.foo2:2.25|g"));
    } finally {
        sink.close();
    }
}
