3.3.1.3.12 NetSpy Daily % Time VR Held/Blocked

INTENDED USE:
 
   This chart displays the percentage of time during the day
   that a virtual route (i.e., backbone link) is held or
   blocked.  "Held" status is the first level of virtual
   route congestion; "Blocked" status is the highest level of
   congestion.  End user response time is prolonged when a
   virtual route becomes held or blocked, because during that
   period no messages can be sent across the route.  Virtual
   route congestion can be caused by such factors as
   insufficient buffers in a down stream NCP or an over-
   utilized boundary link.
 
FORMAT:
 
   This display produces a vertical bar chart of the
   percentage of time that a virtual route is held or
   blocked.

INQUIRY ID:

   Color Graphics:  SNTCDZ
   Printer Graphics:  SNTPDZ

DATA SOURCE (File/Timespan):

   SNTNVR01 - Previous day

DATA ELEMENTS USED:

   SYSID, NVRHSA, NVRDSA, NVRVRRTE, NVRPCTHL

CALCULATIONS:

   None.

USAGE CONSIDERATIONS:

   Use in conjunction with SNTCD5, NetSpy Daily Average VR
   Response Time, to isolate virtual route performance
   problems.  Also use with other MICF inquiries that measure
   link utilization and NCP buffer and cycle utilization to
   isolate the source of the congestion.
