[mrtg] Re: MRTG and IBM2210

[Javier Tan]

Hi all,


I actually have the same problem getting specific object (OID) results from 
MRTG. I'm actually "polling" to a IBM 8265 switch.

I understand from Alex that we can get "response" from certain OIDs as 
Specified in the "SNMP_Util.pm",which MRTG refers to.

I have the following questions:

1. If we need to get results on other objects (OID), do we add them into the 
"SNMP_util.pm" file ??


Hope you guys can help.


Thanks in Advance !!
