The `EventListener.Factory` also makes it possible to limit metrics to a subset of calls. This one captures metrics on a random 10%:

```java
class MetricsEventListener extends EventListener {
  private static final Factory FACTORY = new Factory() {
    @Override public EventListener create(Call call) {
      if (Math.random() < 0.10) {
        return new MetricsEventListener(call);
      } else {
        return EventListener.NONE;

            // Then
            assertNotNull(ra1, "Random access with mode should not be null");
            assertNotNull(ra2, "Random access with sharing should not be null");
            assertSame(mockRandomAccess, ra1, "Should return expected random access");
            assertSame(mockRandomAccess, ra2, "Should return expected random access");
        }
    }
