Easy to use
On the left of the screen, you can see the query configuration panel, this allows you to configure the queries used to generate the graphs that will appear on the right-hand side of the screen.
Clicking the metric dropdown shows a searchable list of all of the metrics available for your account.
In the example we are looking at the application throughput metric, once this metric is selected a graph displaying this metric is automatically generated. By default this graph shows an aggregation of all of the available data in the system for that metric (from all instances and all applications).
