Closed as program error.
Error description
Process Busy CPU (Percent) and most of the other CPU utilization related attributes in the Linux Process attribute group are not normalized to the number of online processors. Only Process Instant Busy CPU (Percent) is normalized. This APAR aims at introducing an environment variable to allow the choice of a coherent behavior for all of these attributes. Defaults will remain unchanged.
Local fix
Split situation into multiple situations, one for each possible value of Number of Processors Online in the Machine Information group.
Problem summary
Incorrect percentages of CPU time consumed by Linux processes The Monitoring Agent for Linux OS may report incorrect values for the following attributes in the Linux Process attribute group, when they exceed 100%: Process System CPU (Percent), Process User CPU (Percent), Cumulative Process System CPU (Percent), Cumulative Process User CPU (Percent), Process Busy CPU (Percent) and Cumulative Busy CPU (Percent) These attributes can exceed 100% on servers with multiple online processors. Also, these attributes are not normalized to the number of online processors, thus preventing 100% to be exceeded, whereas other CPU-related attributes in this group are normalized. In order for this APAR to be properly implemented in your environment, a new environment variable has been added. See the "Install Actions" section of the APAR conclusion for more details.
Problem conclusion
Install Actions: ---------------- A new environment variable introduced to enforce normalization. Default behavior is unchanged. Set KLZ_PROC_CPU_NORMALIZE=True in lz.ini configuration file. The fix for this APAR will be contained in the following maintenance packages: | FixPack | 6.3.0-TIV-ITM-FP0007
