    ****************************************************************
    1. IBM Z Performance and Capacity Analytics Health Metrics
    Scorecard displays excess or irrelevant data.
    a) Rule Thresholds in the Defined Workload
      Priority, Processor Pool Utilization, and Logical Utilization
      information cards are irrelevant.
    b) The text in the Read Hit/Miss Ratio information card contains
      excessive information.
    c) The Processor Pool Utilization detailed report SDP rule
      metric displays thresholds irrelevant to the processor type.
    d) Parked Engines Interval Percent rule metric yellow level
      description is unclear.
    e) The CF Utilization with Thin Dispatch rule level filter
      displays results with disparate rule levels to the selected
      filter.
    f) The Ineffective Simultaneous Multi-Threading detailed report
      displays excess data beyond the MVS System ID filter selected.
    g) The Drawer Memory detailed report rule level filter
      displays a red rule level filter option which is not required.
    h) Health Metrics Scorecard can display lower level results than
      the highest level occurrence for a rule on that date when
      filtered by a Rule Level lower than the highest result.
    i) Some rule information cards display a low and high threshold
      column despite there being no explicit thresholds assigned
      for that particular rule.
    j) Health Metrics Scorecard can display duplicate rows when
     there are multiple MVS System IDs.
    2. IBM Z Performance and Capacity Analytics Health Metrics
    Scorecard does not display some data which is relevant to rule
    level and value calculations, or which would be convenient to
    display.
    a) The DASD Response Time detailed report does not have a
      Device Number column. The I/O Rate and Average Total Response
      Time per I/O values do not correlate with the produced Rule
      Value of the worst performing control unit.
    b) High Logical/Physical ratio detailed report does not have an
      Active LPARs column.
    c) The Workload Utilization detailed report does not display
      corresponding information on Workload Group.
    d) The KPMZHM01 report does not allow users to select more than
      one rule group to display when filtering.
    e) The DASD Contention Intensity detailed report does not have a
      Device Number column.
    3. IBM Z Performance and Capacity Analytics Health Metrics
    Scorecard can display inconsistent data.
    a) The CF Utilization with Thin Dispatch detailed report Rule
      Level results do not match the corresponding result in the
      Health Metrics Scorecard.
    b) The Drawer Memory detailed report rule level results
      does not match the corresponding result in the Health Metrics
      Scorecard.
    c) The rule logic for System Capture Ratio, Variable Interval
      Length, and Paging I/O does not account for some divide by
      zero cases.
    d) Some rule information cards do not contain the full name
      of an abbreviation or abbreviations are not included where
      they could be.
    

Problem conclusion

Temporary fix

Comments

  • 1. IBM Z Performance and Capacity Analytics Health Metrics
    Scorecard is enhanced to remove excess or irrelevant data.
    a) Irrelevant Rule Thresholds removed in the Defined Workload
      Priority, Processor Pool Utilization, and Logical Utilization
      information cards.
    b) The text "BCU" is removed in the Read Hit/Miss Ratio
      information card.
    c) The Processor Pool Utilization detailed report SDP rule
      metric joins on Processor type to produce only the relevant
      threshold.
    d) Parked Engines Interval Percent rule metric yellow level
      description is clarified.
    e) The CF Utilization with Thin Dispatch rule level filter now
      filters to display more correspondent data to the rule level
      selected.
    f) The Ineffective Simultaneous Multi-Threading detailed report
      now displays more accurate data corresponding to the MVS
      System ID filter selected.
    g) The Drawer Memory detailed report rule level filter no longer
      displays a red rule level filter option.
    h) Health Metrics Scorecard now only displays the highest level
      of each rule which occurred for that day. When it is filtered
      by a rule level lower than the highest for the corresponding
      date and rule, the rule will not be displayed on the
      scorecard.
    i) Rule information cards without explicit thresholds assigned
      no longer display an empty low and high threshold column.
    j) Health Metrics Scorecard no longer displays duplicate rows
     when there are multiple MVS System IDs.
    2. IBM Z Performance and Capacity Analytics Health Metrics
    Scorecard is enhanced to display more data relevant to rule
    level and value calculations for increased clarity, or for
    convenience.
    a) Device number column is added to the DASD Response
      Time detailed report. I/O Rate and Average Total Response Time
      per I/O now also correlate to the produced rule value of
      the worst performing control unit.
    b) Active LPARs column has been added to the High
      Logical/Physical ratio detailed report.
    c) The Workload Utilization detailed report is grouped by
      Workload Group and a corresponding Workload Group column has
      been added.
    d) The KPMZHM01 report allows users to select more than
      one rule group to display when filtering via a checklist.
    e) Device number column is added to the DASD Contention
      Intensity detailed report.
    3. IBM Z Performance and Capacity Analytics Health Metrics
    Scorecard is enhanced to display more consistent data.
    a) The CF Utilization with Thin Dispatch detailed report rule
      level results now match the corresponding result in the
      Health Metrics Scorecard.
    b) The Drawer Memory detailed report rule level results
      now match the corresponding result in the Health
      Metrics Scorecard.
    c) The rule logic for System Capture Ratio, Variable Interval
      Length,and Paging I/O accounts for divide by zero cases.
    d) The text for the full name of abbreviations and
      abbreviations themselves have been added to the relevant rule
      information cards.
