3.3.1.3.5 NetSpy Daily NCP Buffer Utilization

INTENDED USE:
 
   This chart helps determine the adequacy and utilization of
   memory in the communications control unit (CCU).
 
FORMAT:
 
   This display produces a vertical bar chart of average free
   buffer queue length in the network control program by
   hour.

INQUIRY ID:

   Color Graphics:  SNTCDQ

DATA SOURCE (File/Timespan):

   SNTNAF01 - Previous day

DATA ELEMENTS USED:

   HOUR, NAFAVFBQ, NCPNAME

CALCULATIONS:

   None

USAGE CONSIDERATIONS:

   This inquiry is produced from the CA NetSpy NCP interface
   data.  After the NCP load module (NCPGEN) is loaded into
   the CCU, the remaining memory is allocated for buffers.
   Thus, the buffering capacity of the CCU is a function of
   the size of the NCPGEN and the amount of installed memory
   in the CCU.  The maximum available NCP buffer's value is
   the number of buffers initially allocated.  The average
   free buffer queue length indicates the number of buffers
   that are generally available.  The free buffer low-water
   mark is the lowest number of buffers that were available
   during the interval.  The average free buffer count at
   slowdown is the number of buffers that were left when the
   CCU became severely memory-constrained.

   Network performance is being impaired if the free buffer
   low-water mark is consistently below the average free
   buffer count at slowdown.  A memory upgrade (if possible)
   should be considered if the average free buffer queue
   length is consistently close to the average free buffer
   count at slowdown.  Otherwise, some of the load on the CCU
   may have to be shifted to another unit.
