DataPower service type metrics displayed in Tivoli Enterprise Portal

Problem

The ITCAM for SOA DataPower Data Collector receives information on DataPower operations and the ITCAM for SOA agent processes that information. Aggregated metrics, for example, message size and response time, for those monitored operations are displayed in Tivoli Enterprise Portal. The Services Inventory table in the Performance Summary workspace contains one row per unique combination of service port name and namespace, operation name and namespace, and service type (provider or requester), for each 5 minute time interval. Please see the Related information section below for a link to more information on the Performance Summary workspace. The Services Inventory table also contains calculations such as average elapsed time. Exports of the table and historical information from the Tivoli Data Warehouse can also include calculated columns for average, minimum, and maximum message size. It may not be clear how the average, minimum, and maximum message size values in a Services Inventory or Data Warehouse export are derived.
