/**
* Sampling handler
*
* A sampled event stream can be useful for logging high frequency events in
* a production environment where you only need an idea of what is happening
* and are not concerned with capturing every occurrence. Since the decision to
* handle or not handle a particular event is determined randomly, the
* resulting sampled log is not guaranteed to contain 1/N of the events that
* occurred in the application, but based on the Law of large numbers, it will
* tend to be close to this ratio with a large number of attempts.
