+<h3 id="export-metrics">9.5 Export metrics</h3>
+<p>Beam metrics can be exported to external sinks. If a metrics sink is set up in the configuration, the runner will push metrics to it at a default 5s period. 
+The configuration is held in the <a href="https://beam.apache.org/releases/javadoc/2.19.0/org/apache/beam/sdk/metrics/MetricsOptions.html">MetricsOptions</a> class.
+It contains push period configuration and also sink specific options such as type and URL. As for now only the REST HTTP and the Graphite sinks are supported and only
+Flink and Spark runners support metrics export.</p>
+
+<p>Also Beam metrics are exported to inner Spark and Flink dashboards to be consulted in their respective UI.</p>
 
 <h2 id="state-and-timers">10. State and Timers</h2>
 <p>Beam’s windowing and triggering facilities provide a powerful abstraction for grouping and aggregating unbounded input
