Cacti tells me: WARNING: Result from SNMP not valid....

Post by Mafkees »

Hi all..

I've set up cacti on my local linux box and - offcourse - want it to graph things like cpu usage etcetera. My local linux machine is being graphed, but when I add the same machine, only by IP-address it won't work. The RRDTool says "ok" so that isn't the problem.. it's just that I don't get SNMP data..

My situation:
I've added a host called chaos and added these three graphs: ucd/net CPU usage, ucd/net load average, ucd/net memory usage but there isn't any data in the graphs created...

Specifications:
CentOS Linux 4.2 Final (RedHat based) (Kernel version 2.6.9-22.0.2.EL)
Apache 2.0.52 (CentOS)
MySQL 4.1.12
PHP 4.3.9

SNMP things installed:
[root@chaos ~]# yum list | grep snmp
net-snmp.i386 5.1.2-11.EL4.6 installed
net-snmp-devel.i386 5.1.2-11.EL4.6 installed
net-snmp-libs.i386 5.1.2-11.EL4.6 installed
net-snmp-perl.i386 5.1.2-11.EL4.6 installed
net-snmp-utils.i386 5.1.2-11.EL4.6 installed
php-snmp.i386 4.3.9-3.9 installed

This is what I get in the (debug) logging:

Now I'm quiet new to SNMP and stuff and I would really like to get these graphs to work..

Thx in advance!

The SNMP client at host chaos must provide the data you've asked for. To check for this, please run the following command

Code: Select all

snmpwalk -c <community> -v 1 chaos system
snmpwalk -c <community> -v 1 chaos load
snmpwalk -c <community> -v 1 chaos cpu
and see, if data is returned. If not, configuration of the snmp client at chaos is required.

The system command seems to work but the load/cpu don't.. indeed there is no data returned:

(Had to replace 'chaos' with the IP address) Maybe I've done something wrong in the SNMP config but I haven't got a clue what it could be..
