SNMP and MRTG... almost giving up

2025-03-31

Urgh ... Following this, I installed SNMP 4.2.3 ... and now (After quite a few hoursss) I am in the point where I am almost giving up ... SNMP has been installed and I can run snmpd fine ... But when I try to use SNMP in my MRTG, I keep getting errors (I think it's snmpget).

When I did /usr/local/mrtg-2/bin/cfgmaker public@localhost > localhost.cfg, I got the following output/errors (some has been taken out to make this shorter):

--base: Get Device Info on public@localhost:

Well ... this alone should tell me that I will not get things to go right ... but I tried anyway with the following mrtg measurement of system load (in localhost.cfg):

WorkDir: /home/dnspro/public_html/mrtg/system

XSize[_]: 400
YSize[_]: 200

OK ... so now running mrtg on this cfg file givess me errors (well, by now ... these are not really suprising ... in fact, it's these are expected SNMP and MRTG... almost giving up

Has anybody been able to configure their MRTG via SNMP? Have I just overlooked anything simple? Any help/advice/info will be greatly appreciated ...

cheers,
SNMP and MRTG... almost giving up
