Example 1 with MetricReceiver

use of com.yahoo.metrics.simple.MetricReceiver in project vespa by vespa-engine.

the class SnapshotConverterTest method testConversion.

@Test
public void testConversion() {
    MetricReceiver mock = new MetricReceiver.MockReceiver();
    mock.declareCounter("foo").add(1);
    mock.declareGauge("quuux").sample(42.25);
    mock.declareCounter("bar", new Point(new HashMap<String, String>())).add(4);
    MetricSnapshot snapshot = new SnapshotConverter(mock.getSnapshot()).convert();
    for (Map.Entry<MetricDimensions, MetricSet> entry : snapshot) {
        for (Map.Entry<String, String> dv : entry.getKey()) {
            assertTrue(false);
        }
        int cnt = 0;
