RMF EADM reporting

With APAR OA56684, RMF is enhanced to report performance metrics for asynchronous compression and decompression activity. Compression and decompression requests are directed to the Extended Asynchronous Data Mover (EADM).

RMF Monitor I collects utilization information of IOP resources used by EADM-compression. The returned utilization information is stored into SMF 78 subtype 3 records. The RMF Postprocessor uses this to report the percentage of IOP Busy for EADM compression activity in the I/O Queuing Activity report.

In addition, with this support, the RMF Postprocessor and Monitor III SCM Activation reports are renamed to EADM Activity reports. Both reports continue to provide RMF users with SCM activity data.

The number of compress and decompress operations as well as the number of input and output bytes for asynchronous compression and decompression are stored in SMF 74 subtype 10 and into the Monitor III Set-of-Samples. These numbers are used by the RMF Postprocessor and Monitor III to calculate and display compression and decompression request rates, throughput and ratios in the new Compression Activity report section of the Postprocessor EADM Activity report and in the Monitor III EADM Activity report header section.

To control the collection of EADM data, use the EADM Monitor III data gatherer option.

To control the reports to be generated by the Postprocessor for a single system, use the REPORTS control statement.

An IOPECB condition has been added to I/O Queuing Activity conditions based on SMF Record Type 78-3.
