    +Metrics
    +-------------------
    +
    +Flink exposes a metric system that allows users gather and expose metrics to external
systems.
    +
    +### Registering metrics
    +
    +You can access the metric system from any user function that extends [RichFunction]({{
site.baseurl }}/apis/common/index.html#rich-functions) by calling getRuntimeContext().getMetricGroup().
