5.2.8.3 Usage Considerations



Special considerations or techniques related to using the
HARLPC file are provided below.

1.  The following data elements in the HARLPC file have
    meaning only in the DETAIL timespan; they lose
    significance once summarization has been performed.
    These data elements should only be referenced when using
    the HARLPCnn file in the DETAIL timespan.

    CYCLETM  - Sampling Time Cycle Length
    LPCBPS   - Processor Relative Share
    LPCWST   - Wait State Assist Status

2.  The following data elements are user-defined and option
    dependent. Their use should be within the frame of
    reference of the option's definition.

    CA MICS PARMS SYSID
    CPUMODEL - CPU Model Identification

3.  Care must be exercised in using the special date and time
    data elements contained in each CA MICS file. As the
    file's granularity increases in higher timespans, certain
    fields lose significance and should not be used.

    o  HOUR should not be used in MONTHS.
    o  DAY and DAYNAME should not be used in WEEKS, MONTHS.
    o  WEEK should not be used in MONTHS.

4.  ENDTS and STARTTS, when appearing in the DAYS, WEEKS, or
    MONTHS timespans, bound the amount of time during which
    the data has been summarized.  STARTTS is the lowest date
    and time, and ENDTS is the highest date and time for the
    data summarized.  These data elements have different
    meanings when used in the DETAIL timespan versus the
    DAYS, WEEKS, and MONTHS timespans.  Their purpose in
    DETAIL is described below:

    o  STARTTS represents RMF recording interval start time.
    o  ENDTS represents RMF recording interval end time.
