[mrtg] Re: 5 minute cron and RRD Tool <- continued

[Ambrose Chiu]

First of all I don't think its the snmpd that is giving you those
messages. You can get snmp values anytime even by just doing a snmpwalk
or snmpget. Those error messages don't give much insight as to what's
going on. Try checking the mail for the user you are running mrtg with
(ex: root mail is under /var/spool/mail/). Those message logs usually
give the full detail of what went wrong.

Another suggestion is to run the mrtg target manually to see if it gives
any error messages since mrtg won't store anything if an error comes up
and your graphs will be halted.
