4755.0. "Graph Utilization Queries?" by HOLST::LIONEL () Wed Mar 24 1993 09:18

I have installed ELM & MCC V1.3 and am finding difficulty understanding the 
network utilization graphs. The basic hardware configuration is as follows:-


	  concentrator
		|
		|
	---------------		
	|DECBRIDGE 620|		
	|	      |		
	--2-----3-----4
	  |	|     |
	File   Alpha
      Server   Box

Results:

I am transferring large amounts of data from the file server to the alpha box. When
I monitor line 2 on the decbridge during this transfer it shows me 40% network 
utilization and on monitoring line 3 during this time the network utilization shows
about 0.5% and the single destination utilization on line 3 shows 40%.

Question 1:

To my mind if line2 is sending the data and line 3 is receiving the 
same data then the network utilization graphs should be the same or am I missing 
something?? 


Question 2:

What is causing this difference between the single destination utilization and 
network utilization graph??


Thanks,
	Lionel.

    re: .0
    We also have problems with the utilization figures for the DECbridges.
    I suspect that there is a bug either with the DECbridge firmware or
    the calculations that DECmcc is doing.
    I have an outstanding CLD on this....
