Implement Hdwe. Instr. Svc. (HIS) on TPF

TPFUG_Req_Number: S13001
ORIGIN DATE: 3/26/2013
REQUIREMENT ABSTRACT

Relative Nesting Intensity(RNI) is a new hardware measurement available on z10 and later hardware. IBM should report data through TPF performance utilities.

REQUIREMENT DESCRIPTION
The measurement capability was first introduced in the z10 class processors. The TPF utility to collect the measures is available, but sending data to IBM to get a report is an ineffective means to evaluate the data. Introducing the data into continuous data collector, or other similar processing should be provided for reporting and evaluation of the data.

CRITICAL SUCCESS FACTORS

Reporting can be provided through current processing of cpu utilization, IO, and memory utilization measurements. If the current collection doesn't include continuous and sampling of the data, the CPU measurement data collection utility should be modified to do so. The reporting solution should be enabling automated processing that provides timely and easy access to the data for evaluation. For example: Desktop/excel summaries, and/or SQL based data repositories.

ALTERNATIVE SOLUTIONS



SOLUTION CONSIDERATIONS (required)

Simply writing the data out to a memory, disk or tape file is not helpful for customers running TPF. A means to process the collected data for evaluation is basic to delivery of the information where it can be helpful. Since IBM is moving toward pricing models for software based on these metrics, it is sensible to provide customers a means to evaluate the effects of their technology decisions on that pricing, as well as, make improvements in their TPF applications.
