The Performance Data Collection Engine (PDCE) is a module inside the Performance Explorer engine that is used for querying monitoring data in real-time. Its functionality can alternately be accessed through the Benchmark Description Language (BDL). The BDL interface for the PDCE is described in the pdce.bdh include file.
Each of the measurements that Performance Explorer monitors can alternately be monitored via Silk Performer using BDL scripts. After registering measurements of interest, a monitoring data set can be retrieved from the PDCE via the provided polling functions (PDCE API). These functions provide data, status information, and descriptions of the measurements (if available).
