Charts display the values of metric attributes in MBean instances. The values can be real-time polled metric values obtained from a running WebLogic Server instance, or they can provide a historical view of that metric value that is maintained by the WLDF Harvester. For information, see Configuring the Harvester for Metric Collection.
