[mrtg] customize OID problem

Try adding a .0 suffix to the OIDs?  This can often solve the issue as some programs suppress  this on display.

The MRTG error is saying that it is unable to retrieve the OID, and the 'undefined data' message is because the value is now undefined because it could not be retrieved.

Subject: Re: [mrtg] customize OID problem  is window 2003 server  , and there is one applicaiton that enable  snmp-agent .

i can use other MIB Browser application to get the information using the same OID ,

so OID is correct and snmp version is correct , i think .

if is it possible that the target name is wrong  because of snmp-agent ?

the error is : "ERROR: Target[][_IN_] ' $target->[0]{$mode} ' did  not eval into defined data "

and what does it mean about defined data , where i can find the defined data ?

waiting ...

thanks .
