Dear James

actually I do not know how to use expressions with MIB Browser. I think that 
MIB browser accepts MIB objects only ( because it returns absolute values 
without any delta calculations)
this device responds to any MIB object query using MIB Browser

>>  (2) Have you already been collecting BandwidthUtilIn data with snmpCollect?

Yes, data collection for BandwidthUtilIn is working correctly

actually james I don't see any difference between graphing  a MIB object like 
ifInOctets and graphing an expression like BandwidthUtilIn regarding the delta 
Calculations. the only difference in my view is that in the second case two MIB 
objects ( ifInOctets & ifSpeed ) will be queried in stead of one MIB object.

I read in this forum that some guys can plot expressions in real-time using 
xnmgraph on Linux environment so what I want to know is whether I can do this 
on windows platform  or not. 

thanks for your time and help

  Two questions:

  (1) If you query this same device for BandwidthUtilIn using the MIB Browser, 
does it respond with data?
  (2) Have you already been collecting BandwidthUtilIn data with snmpCollect? 
To draw a graph of something like BandwidthUtilIn you need a value for the 
delta, for change over unit time, which means you'd need at least two data 
points to begin with.

              [nv-l] problem with realtime plotting of expressions with 
graph.exe 
              
       

  Hi all

  we are using netview 7.1.4 over windows 2000 server

  when I apply the following command:
  graph.exe -mib 1.3.6.1.2.1.2.2.1.10::1:::::: 10.10.1.1

  graph.exe window is opened and plots ifInOctets of instance 1 for 10.10.1.1 
node

  when I put instead of mib OID an expression like following command

  graph.exe -mib BandwidthUtilIn::1:::::: 10.10.1.1

  graph.exe window is opened for about 10 seconds then it is closed with out 
giving any error message or logging any thing in nv.log
  when I use a wrong expression name it gives an error "could not convert 
expression or mib variable"
  this means that graph resolves the BandwidthUtilIn correctly.

  thanks for your help
