[mrtg] Re: OID problem

[Adam Stanley]

try looking in the documentation for snmp - there is a prefix of numbers
that need to be added before the OID you have displayed.  When you use
snmpget and define the OID as "##.##.##.##..." it prepends the prefix
automatically.  If you were to run snmpget with the OID defined as
".##.##.##.##..." it wouldn't work.  It's possible MRTG doesn't attach the
prefix to the OID automatically like snmpget does - but I'm not positive.
