Examples with SensorAccessor org.apache.kafka.common.metrics.SensorAccessor used on opensource projects

Example 1 with SensorAccessor

use of org.apache.kafka.common.metrics.SensorAccessor in project kafka by apache.

the class SourceNodeTest method shouldExposeProcessMetrics.

@Test

    final Metrics metrics = new Metrics();
    final StreamsMetricsImpl streamsMetrics = new StreamsMetricsImpl(metrics, "test-client", StreamsConfig.METRICS_LATEST, new MockTime());

    final SourceNode<String, String> node = new SourceNode<>(context.currentNode().name(), new TheDeserializer(), new TheDeserializer());
    node.init(context);
    final String threadId = Thread.currentThread().getName();
    final String groupName = "stream-processor-node-metrics";
    final Map<String, String> metricTags = mkMap(mkEntry("thread-id", threadId), mkEntry("task-id", context.taskId().toString()), mkEntry("processor-node-id", node.name()));
    assertTrue(StreamsTestUtils.containsMetric(metrics, "process-rate", groupName, metricTags));
    assertTrue(StreamsTestUtils.containsMetric(metrics, "process-total", groupName, metricTags));
    // test parent sensors
