<p>Drill uses JMX (<a href="https://docs.oracle.com/javase/tutorial/jmx/";>Java
Management Extensions</a>) to monitor queries at runtime. JMX provides the
architecture to dynamically manage and monitor applications. JMX collects Drill
system-level metrics that you can see in the Metrics tab in the Drill Web UI or
a remote JMX monitoring tool, such as JConsole or the VisualVM + MBeans plugin.
