Example 3 with MetricMatcher

use of com.wavefront.agent.config.MetricMatcher in project java by wavefrontHQ.

the class LogsIngesterTest method testHotloadedConfigClearsOldMetrics.

@Test

    assertThat(getPoints(1, "plainCounter"), contains(PointMatchers.matches(1L, MetricConstants.DELTA_PREFIX + "plainCounter", ImmutableMap.of())));
    // once the counter is reported, it is reset because now it is treated as delta counter.
    // hence we check that plainCounter has value 1L below.
    assertThat(getPoints(2, "plainCounter", "counterWithValue 42"), containsInAnyOrder(ImmutableList.of(PointMatchers.matches(42L, MetricConstants.DELTA_PREFIX + "counterWithValue", ImmutableMap.of()), PointMatchers.matches(1L, MetricConstants.DELTA_PREFIX + "plainCounter", ImmutableMap.of()))));

    // this one.

    logsIngestionConfig.counters = counters;
    logsIngesterUnderTest.logsIngestionConfigManager.forceConfigReload();

    // since zero values are filtered out, no new values are expected.
