Urgh ... Following this (http://net-snmp.sourceforge.net/#Documentation), 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):

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

Target[cpusum]:ssCpuRawUser.0&ssCpuRawUser.0:public@localhost + ssCpuRawSystem.0&ssCpuRawSystem.0:public@localhost + ssCpuRawNice.0&ssCpuRawNice.0:public@localhost

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 :( )

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,

Is it possible that public is not the correct community name?

Hi,

Whats the output of the following command




snmpwalk -c public localhost


You should get something like this

Also make sure you have snmpd (the daemon) running. Start is by running the command snmpd. If you are unsure of there location, just do a whereis snmpd or whereis snmpwalk


From there I will see if i can help you

thank you for the replies ...

running snmpd by invoking /etc/rc.d/init.d/snmpd start

I see there is a timeout error ... hm ... what does it mean? Getting close ... I will do some more research (but if you what the problem is, don't hesitate to help me out ;) )... Thanks ...

cheers,
:beer:

Do you have a firewall setup? Are you using the latest vs of snmpd?
