[mrtg] Re: SNMPGET ERROR : "did not eval into defined data"

[Koelstra, J. (Jan)]

Ingrid,

Your problem is basicaly an SNMP problem. The best way to resolve this is by using a MIBbrowser from the same machine where you have installed MRTG.
For MIBbrowser on your Windows system I recommend GETIF (http://www.wtcs.org/snmp4tpc/getif.htm). A commandline alternative is SNMPUTIL.EXE from the Windows resourcekit.
With this you can check if your target machine does respond to any SNMP request at all, and if so then check if the oid you use is a valid oid at your target machine.

HTH,

Jan.

Hi,
I just install a MRTG server for testing.
I have a problem with a request like this one :
PageTop[_]:Test

ShortLegend[_]:MBIT
MaxBytes[_]:1000000000

Target[xx.xx.xx.xx_1]: .1.3.6.1.2.1.16.6.2.1.1&.1.3.6.1.2.1.16.6.2.1.1:
public at xx.xx.xx.xx <rafale at 10.128.32.150>
Title[xx.xx.xx.xx_1]: TEST

WorkDir: c:\mrtg\work
