Exclamation MRTG problem


I've setup net-SNMPD and MRTG, but MRTG returns errors.

I'm installing it on new server - Mandriva 2007. I have old server - Mandriva 2006 and it is working on it.

MRTG config file:
Code:
# File: /etc/mrtg/server-info.cfg
#
# Configuration file for non bandwidth server statistics
#


#
# Define global options
#

LoadMIBs: /usr/share/snmp/mibs/UCD-SNMP-MIB.txt,/usr/share/snmp/mibs/TCP-MIB.txt,/usr/share/snmp/mibs/HOST-RESOURCES-MIB.txt,/usr/sh
are/snmp/mibs/HOST-RESOURCES-TYPES.txt

workdir: /var/www/html/mrtg/

I tried to use snmpwalk and it looks OK:
Code:
[root@m6 ~]# snmpwalk -v1 -c test localhost ssCpuRawUser 
UCD-SNMP-MIB::ssCpuRawUser.0 435141

What am I doing wrong?
Can someone help me with this?

Wink Madness - ok not really.

This was bugging me for a few hours until i came across a doc that recommended using full ID numbers rather than short names.

Mandriva 2008 - spring, Base install, used URPMI ( urpmi ) to install mrtg and Dependants.
Then used cfgmaker and indexmaker to create files.

Some Graphics didn't build properly and manually running
env LANG=C /usr/bin/mrtg /etc/mrtg/mymrtg.cfg i could not see some OID's when referenced by short names woud error out. However snmpwalk would work properly

Delving into my config file what i found is preempted by a #, and what i changed it to is on the bottom line.

CPU Monitoring
**original**
#Target[server.cpu]: ssCpuRawUser.0&ssCpuRawUser.0ublic@localhost + ssCpuRawSystem.0&ssCpuRawSystem.0ublic@localhost + ssCpuRawNice.0&ssCpuRawNice.0ublic@localhost
**changed/updated**
Target[server.cpu]: 1.3.6.1.4.1.2021.11.50.0&1.3.6.1.4.1.2021.11.50.0ublic@localhost + 1.3.6.1.4.1.2021.11.53.0&1.3.6.1.4.1.2021.11.53.0ublic@localhost + 1.3.6.1.4.1.2021.11.52.0&1.3.6.1.4.1.2021.11.52.0ublic@localhost

[root@vortex ~]# snmpwalk -v 2c localhost -c public ssCpuRawUser.0
UCD-SNMP-MIB::ssCpuRawUser.0 496112

[root@vortex ~]# snmpwalk -v 2c localhost -c public .1.3.6.1.4.1.2021.11.50
UCD-SNMP-MIB::ssCpuRawUser.0 496112


So in short replace the short name with the full OID.
