Examples with Counter org.apache.calcite.avatica.metrics.Counter used on opensource projects

Example 1 with Counter

use of org.apache.calcite.avatica.metrics.Counter in project calcite-avatica by apache.

the class DropwizardMetricsSystemTest method testCounter.

@Test
public void testCounter() {
    final String name = "counter";
    final com.codahale.metrics.Counter mockCounter = mock(com.codahale.metrics.Counter.class);
    when(mockRegistry.counter(name)).thenReturn(mockCounter);
    Counter counter = metrics.getCounter(name);
    long[] updates = new long[] { 1L, 5L, -2L, 4L, -8L, 0 };
    for (long update : updates) {
        if (update < 0) {
            counter.decrement(Math.abs(update));
        } else {
            counter.increment(update);
        }
    }
    for (long update : updates) {
        if (update < 0) {
            verify(mockCounter).dec(Math.abs(update));
        } else {
            verify(mockCounter).inc(update);
        }
    }
    int numSingleUpdates = 3;
    for (int i = 0; i < numSingleUpdates; i++) {
        counter.increment();
        counter.decrement();
    }
    verify(mockCounter, times(numSingleUpdates)).inc();
    verify(mockCounter, times(numSingleUpdates)).dec();
}

Example 2 with Counter

use of org.apache.calcite.avatica.metrics.Counter in project calcite-avatica by apache.

the class NoopMetricsSystemTest method testNoNulls.

@Test
public void testNoNulls() {
    // The NOOP implementation should act as a real implementation, no "nulls" allowed.
    MetricsSystem metrics = NoopMetricsSystem.getInstance();
    Counter counter = metrics.getCounter("counter");
    counter.decrement();
    counter.increment();
    counter.decrement(1L);
    counter.increment(1L);
    Histogram histogram = metrics.getHistogram("histogram");
    histogram.update(1);
    histogram.update(1L);
    Timer timer = metrics.getTimer("timer");
    Context context = timer.start();
    context.close();
    Context contextTwo = timer.start();
    assertTrue("Timer's context should be a singleton", context == contextTwo);
    Meter meter = metrics.getMeter("meter");
    meter.mark();
    meter.mark(5L);
    metrics.register("gauge", new Gauge<Long>() {

        @Override
        public Long getValue() {
            return 42L;
        }
    });
