It would be nice to somehow generalize the JMX connector to a metrics connector. That way you could additionally query coordinator metrics, which include aggregate cluster-wide metrics, without having to add a separate catalog.
Presto java has a JMX connector to query Presto node metrics in SQL queries. This is very useful in monitoring system health. https://prestodb.io/docs/0.284/connector/jmx.html?highlight=jmx%20connector
Native engine doesn't have JMX metrics. But there are other efforts for metrics collection in Native engine. Exposing these via catalog tables would really help as well.
