5.3.6.3 DEMSPR Usage Considerations

1.  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 referenced:

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

2.  The data elements STARTTS and ENDTS have different
    meanings when used in the DETAIL timespan from when they
    are used in the DAYS, WEEKS, MONTHS, and YEARS timespans.
    The ENDTS and STARTTS, when appearing in the higher
    timespans, indicate the span of time over which the data
    has been summarized.  STARTTS indicates the beginning of
    the timespan and ENDTS indicates the end of the timespan.

3.  The following data elements only have meaning when using
    the DEMSPRnn file in the DETAIL timespan, in that they
    lose significance once summarization has been performed.
    These data elements should only be referenced when using
    the DEMSPRnn file in the DETAIL timespan.

4.  File Content

    The VMS System Profile file is constructed by joining the
    information from the following VMS MONITOR records.

    o  VMS MONITOR STATES Record
    o  VMS MONITOR PAGE Record
    o  VMS MONITOR IO Record
    o  VMS MONITOR FCP Record
    o  VMS MONITOR POOL Record
    o  VMS MONITOR LOCK Record
    o  VMS MONITOR DECNET Record
    o  VMS MONITOR FILE SYSTEM CACHE Record
    o  VMS MONITOR DLOCK Record
    o  VMS MONITOR SYSTEM Record
    o  VMS MONITOR CLUSTER Record
    o  VMS MONITOR MSCP SERVER Record
    o  VMS MONITOR TRANSACTION Record

    The data element SPRMASK (Record Construction Audit Mask)
    is a 13-byte element in the DEMSPR file, with each byte
    signifying the presence or absence of a particular record
    type used to construct each observation of the file.
    SPRMASK is meaningful only at the DETAIL level of
    summarization.  See the data element description for more
    information on this field.
