Dear all,
Thank you very much for your great tool.
I have installed MRTG latest version "mrtg-2.16.3" yesterday, but I am facing a lot of problems.

I got in the CLI tons of errors in the form:

Error 1:

2010-04-19 09:08:43: ERROR: Target[Router IP_Interface IP][_OUT_] ' $target->[17]
{$mode} ' did not eval into defined data


Error 2:

2010-04-19 09:04:54: WARNING: Could not match host:'Community string at Router IP:'
ref:'Ip' key:'Interface IP'


Error 3:

SNMP Error:

                  community: "Community_string"

SNMPGET Problem for ipAdEntIfIndex."Interface_IP" ifInOctets.21 ipAdEntIfIndex.."Interface_IP" ifOutOctets.21 sysUptime sysName on Community_String at Router_IP::::::v4only

Please help me how to resolve the above 3 errors, as I am feeling that the utilization values are not accurate.
I appreciate your help.
Thanks a lot.
Best Regards,
