eth0 Traffic Graph Not Working

[cthielen]

New to Cacti -- installed on CentOS 5.7 using these instructions: http://www.cyberciti.biz/faq/fedora-rhe ... -software/ .

Graphs of load average, memory usage, processes, and logged in users work fine. Those appeared by simply following the instructions.

I then added graphs of traffic for eth0 (main interface), eth1 (unused), lo, and sit0. Those graphs are completely void of data.

They are implemented using the graph template "Interface - Traffic", being fed by data sources "Localhost - Traffic - my_ip_address - eth0 (traffic in)" and "Localhost - Traffic - my_ip_address - eth0 (traffic out)".

I have the following Data Queries:
Karlnet - Wireless Bridge Statistics Get SNMP Data (Indexed)
Netware - Get Available Volumes Get SNMP Data (Indexed)
Netware - Get Processor Information Get SNMP Data (Indexed)
SNMP - Get Mounted Partitions Get Script Server Data (Indexed)
SNMP - Get Processor Information Get Script Server Data (Indexed)
SNMP - Interface Statistics Get SNMP Data (Indexed)
ucd/net - Get Monitored Partitions Get SNMP Data (Indexed)
Unix - Get Mounted Partitions Get Script Data (Indexed)

and the following Data Input Methods:

Linux - Get Memory Usage Script/Command
Unix - Get Free Disk Space Script/Command
Unix - Get Load Average Script/Command
Unix - Get Logged In Users Script/Command
Unix - Get System Processes Script/Command
Unix - Get TCP Connections Script/Command
Unix - Get Web Hits Script/Command
Unix - Ping Host Script/Command

What am I doing wrong?

Is the SNMP daemon working on your host?

I believe so:

[root@host ~]# /etc/init.d/snmpd status
snmpd (pid 2647) is running...
[root@host ~]# snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.1.1.0
SNMPv2-MIB::sysDescr.0 = STRING: Linux the_host 2.6.18-274.12.1.el5PAE #1 SMP Tue Nov 29 14:16:58 EST 2011 i686

Does this command work?
% snmpwalk -v 1 -c public localhost .1.3.6.1.2.1.2.2.1

Just wanting to bump this up. SNMP is apparently working. eth0 graph still empty.

The graph itself says it is using data sources "traffic_in" and "traffic_out". When I click "Data Source Debug" for those sources, I get:

/usr/bin/rrdtool create \
/usr/share/cacti/rra/localhost_traffic_in_15.rrd \
--step 300 \
DS:traffic_in:COUNTER:600:0:U \
DS:traffic_out:COUNTER:600:0:U \
RRA:AVERAGE:0.5:1:600 \
RRA:AVERAGE:0.5:6:700 \
RRA:AVERAGE:0.5:24:775 \
RRA:AVERAGE:0.5:288:797 \
RRA:MAX:0.5:1:600 \
RRA:MAX:0.5:6:700 \
RRA:MAX:0.5:24:775 \
RRA:MAX:0.5:288:797 \

Any ideas why this isn't tracking eth0? The graph remains empty.

Run the poler from the command line and post the results. You should also check the first and second posts in my signature.

Thanks, that fixed it. One of the files didn't have the right permissions. Appreciated greatly!
