+> VisualVM Trace provides detailed monitoring and analyzing Java applications. Using various probes, 
+> the Tracer gathers metrics from an application and displays the data in a timeline. The data are 
+> displayed both graphically and in a table and can be exported to common formats for further processing 
+> by external tools.
+
+When you connect to a cluster via JMX, you will see the `Tracer` tab as shown below:
