[mrtg] Re: MRTG not getting bandwidth data

[James Calamore]

You are right - it doesn't appear to be a problem with MRTG.  I tried snmpwalking and was able to get non-zero responses on some of the interface MIB's (i.e. IfIndex, ifDescr, ifType, ifMtu, ifSpeed, ifPhysAddress, ifAdminStatus, ifOperStatus, and ifLastChange) and also the system MIB's.  However, here are the zero value responses that I received (which is the reason why MRTG isn't capturing my bandwidth data):

IF-MIB::ifInOctets.16 = Counter32: 0
IF-MIB::ifInUcastPkts.16 = Counter32: 0
IF-MIB::ifInNUcastPkts.16 = Counter32: 0
IF-MIB::ifInDiscards.16 = Counter32: 0
IF-MIB::ifInErrors.16 = Counter32: 0
IF-MIB::ifInUnknownProtos.16 = Counter32: 0
IF-MIB::ifOutOctets.16 = Counter32: 0
IF-MIB::ifOutUcastPkts.16 = Counter32: 0
IF-MIB::ifOutNUcastPkts.16 = Counter32: 0
IF-MIB::ifOutDiscards.16 = Counter32: 0
IF-MIB::ifOutErrors.16 = Counter32: 0
IF-MIB::ifOutQLen.16 = Counter32: 0
IF-MIB::ifSpecific.16 = Counter32: 0

Has anyone come across this issue before?

Thanks!
James

Try accessing the snmp daemon using snmpget, snmpwalk or similar tools.
Only when this works, start thinking about debugging MRTG.

Perhaps your daemon doesn't work properly or is configured in a way you
don't expect.  You'd be wasting your time if you'd look at MRTG.
