This is about providing new types of charts and chartable fields in the admin console, to provide a broader choice for user-defined charts.

For instance:

• stacked area charts could clearly show how node execution time + transport overhead add up
• having a new field for busy nodes would make it easy to see the distribution of idle vs. busy nodes in a pie or ring chart
• adding the number of active / inactive nodes as fields
• using some aggregates of the JVM health information, like avg cpu load, memory usage, etc.
