3134.0. "NODE statistics (utilization percent = 0)" by ANNECY::BONNIER (Jean-Luc ... EIC/T&N Annecy France) Fri Jun 05 1992 09:39

I am running VMS 5.5 and DECmcc BMS T1.2.7.
I have a question related to DECnet/OSI entities and Perf. Analyzer FM.

When doing

MCC> show node aeo528 csmacd station csmacd-1 all statistics

I don't understand why the 'inbound/outbound utilization' is 0 Percent.

Node DSP_NS:.aeo528 CSMACD Station csmacd-1
AT  5-JUN-1992 11:30:35 Statistics

Examination of attributes shows:
                               Duration = 59 Seconds
                   Outbound Utilization = 0 Percent
                    Inbound Utilization = 0 Percent
              Average Outbound PDU Size = 94.17 Octets
               Average Inbound PDU Size = 85.07 Octets
                      Outbound PDU Rate = 0.1 pdus/sec
                       Inbound PDU Rate = 0.46 pdus/sec
                Outbound Multicast PDUs = 0 Percent
		Outbound Multicast PDUs = 0 Percent
                 Inbound Multicast PDUs = 77.78 Percent
   CSMACD Contention with no Collisions = 0 Percent
      CSMACD Contention with Collisions = 0 Percent
   CSMACD Contention with One Collision = 0 Percent
CSMACD Contention with Multiple Collisions = 0 Percent
                Count of Inbound Octets = 565
               Count of Outbound Octets = 2297
                 Count of Outbound PDUs = 6
                  Count of Inbound PDUs = 27
        Inbound PDUs Lost due to Errors = 0 Percent
 Outbound PDUs terminated due to Errors = 0 Percent
Count of PDUs Lost due to Data Overruns = 0
Count of PDUs Discarded No Station Buffers = 0
Count of PDUs Discarded No User Buffers = 0
Count of Collision Detect Check Failures = 0
        Count of Carrier Check Failures = 0
                 Count of PDUs Too Long = 0
          Count of Excessive Collisions = 0
               Count of Late Collisions = 0
              Count of Station Failures = 0
                          Error Percent = 0
                    
The PA manual explains the formulae for these percent values.
Are they really calculated ?

Thanks for your help.
