Dynamic cache counters

Use this page as a reference for properties of dynamic cache counters.

You can use the Performance Monitoring Infrastructure (PMI) data for dynamic cache to monitor the behavior and performance of the dynamic cache service. For information on the functions and usages of dynamic cache, refer to Task overview: Using the dynamic cache service to improve performance .

Use the dynamic cache MBean to access the related data and display it under dynamic cache in the Tivoli Performance Viewer (TPV).
