sorry I resend this problem because i received no reply. Any one can help?
Dear James
 
>> (1) If you query this same device for BandwidthUtilIn using the MIB Browser, does it respond with data?
 
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

Subject: [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
