IntelliMagic Vision provides visibility into the widely-used transaction level metrics available in the RMF 72 records, including transaction rate, transaction response time, average concurrent transactions, CPU and I/O per transaction, and total CPU and I/O activity.
Obtaining key metrics for CICS, DB2, and IMS transactions has historically required processing massive volumes (often hundreds of millions or more) of SMF 110 records (for CICS), SMF 101 records (for DB2), and subsystem log records (for IMS). Extracting, transmitting, and processing these enormous volumes of records has typically been a very CPU-intensive task requiring many hours of elapsed time.
But now (as an unexpected “side benefit” of IBM’s Mobile workload pricing support) key transaction level metrics are available in the RMF type 72 records, at the service class or report class level. You can take advantage of this capability by mapping transactions of interest into a set of report classes using the wide range of classification methods available in WLM.
