3176.0. "PA on Decrouter 250 in v1.2-7, are data reliable ??" by MLNCSC::BARILARO () Fri Jun 12 1992 09:15

Hi,

	I've a question on the PA on Decrouter 250.
	I know that there's a problem on v1.1, the "Show Statistics"
	on the line doesn't work, I test the same function on v1.2-7
	and it's work, to be sincere seems to me that it works TOO MUCH. 

	I mean that the "Show Statistic" on a line shows a lot of infos
	and I don't know where it takes this info, surely not in NCP.

    
    	
	The NCP counters for a async line on Decrouter 250 are:
  
Known Line Counters as of 12-JUN-1992 11:12:51
 
Line = ASYNC-1
 
      >65534  Seconds since last zeroed
           0  Remote process errors
           0  Local process errors

    
	The "Show Statistic" shows these infos:
	

DECmcc (T1.2.7)


Node4 2mln62 Line async-1 
AT 12-JUN-1992 12:18:44 Statistics

Examination of Attributes shows:
                               Duration = 59 Seconds
                   Outbound Utilization = 1.1 Percent
                    Inbound Utilization = 0.1 Percent
            Average Outbound Block Size = 54
             Average Inbound Block Size = 31
                    Outbound Block Rate = 3 Blocks/Sec
                     Inbound Block Rate = 1 Blocks/Sec
          Count of Local Reply Timeouts = 0
         Count of Remote Reply Timeouts = 0
             Outbound Data Frame Errors = 0
              Inbound Data Frame Errors = -- Attribute Not Available
           Count of Local Buffer Errors = 0
          Count of Remote Buffer Errors = 0
            Count of Selection Timeouts = 0
   Count of Selection Intervals Elapsed = 0
         Count of Remote Station Errors = 0
          Count of Local Station Errors = 0
                          Error Percent = -- Attribute Not Available
                         Outbound Bytes = 32634 Bytes
                          Inbound Bytes = 1244 Bytes
                   Outbound Data Blocks = 1126 Blocks
                    Inbound Data Blocks = 551 Blocks

	
	So my question is, how it's possible to have the "Outbound Utilization"
	(for example) without having the corrispondent "Bytes sent" counter 
	in NCP for this line ????

	I don't feel confident to tell to the customer that this data are
	reliable.


					Thanks in advance,
					Ciao Luciano

3176.1	For confidence, work through the calculations.	TOOK::A_MOORE	`Fri Jun 12 1992 09:43`	11
	The seconds since last zeroed counter is latched. It need to be zeroed. The > indicates it is latched. >65534 This will skew the statistics. The back of the PA manual has all the calculations and sources of all the data for the calculation. If you work the calculations I think you will feel confident. They have been reviewed and checked extensively. Al
3176.2	Line stats use circuits counters	MLNCSC::BARILARO	`Fri Jun 12 1992 10:36`	12
	Hi, I found like you suggest on the PA manual (appendix A, page A-3) the calculation that I need, and I've understand that for DDCMP and X25 line you have to use all the circuits counters for this line, this's correct because you could have more than 1 circuit using the same line. Thanks a lot Ciao Luciano
