5.3.3.3 VMXSGP Usage Considerations

This file contains information from data reported at the
system level, configuration data, and information summarized
from the processor level.  Special considerations or
techniques related to using the VMXSGP file are provided
below:

o  The VMXSGP file is constructed primarily from SYSTEM
   domain and STORAGE domain data, however the elements
   SGPESWSS (Sum of the Estimated Working Set Sizes of In
   Queue Users), SGPACTIV and SGPACTVV (Users Active in Total
   Time and Virtual Time) are derived from the VMXVXU file.
   If all virtual machines are not monitored in the USER
   domain, these elements will not contain accurate data.
   This will affect other elements in the VMXSGP file that
   are calculated using any of the above-named elements.

o  The VMXSGP file contains data that is summed for all
   processors in the complex.  This information comes from
   the VMXSPP file.  The VMXSGP data element pertaining to
   CPU use are derived from the VMXSPP file.  A separate
   element named SGP002TM is kept on the file that represents
   the duration over which these CPU times are accumulated.
   This is done so that the real sum of elapsed time over all
   processors is available rather than an approximation based
   on the DURATION element.
