  - dump
```
public void dump(BiConsumer<String,Object> sink)
```
    Dump all values to the 4lw interface and to the Admin server.
    This method is not expected to be used to serve metrics to Prometheus. We are using the MetricsServlet provided by Prometheus for that, leaving the real representation to the Prometheus Java client.
