Si quieres capturar excepciones y crear un response personalizado en base a eso, crea un [Manejador de Excepciones Personalizado](../handling-errors.md#install-custom-exception-handlers).

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) {

            .where(
                new TypeCapture<Iterable<Map<?, V>>>() {}.capture(),
                new TypeCapture<Iterable<Map<String, Integer>>>() {}.capture());
    assertEquals(
        new TypeCapture<K>() {}.capture(), resolver.resolveType(new TypeCapture<K>() {}.capture()));
    assertEquals(Integer.class, resolver.resolveType(new TypeCapture<V>() {}.capture()));
  }
