Zabbix agent not passing on all data to master.

[Metrotyranno]

I'm having a problem with one of my agents.

Networking data is not sent to the zabbix server but other data like cpu is.

~# zabbix_agentd -t "system.cpu.load[all,avg1]"
system.cpu.load[all,avg1] [d|3.270000]
~# zabbix_agentd -t "net.if.in[eth0]"
net.if.in[eth0] [u|157171693666]

Network: http://puu.sh/jaaWk/419357f416.png
Ram on the same box: http://puu.sh/jaaYk/9b99b4ccfd.png

Does anyone know how I can resolve this?

Has anyone got a clue?

[Metrotyranno]

I just found out that all NEW servers don't report network data, all the old ones however report as normal.

Just added my 3rd EU server, now EU1 is reporting, EU2 and 3 are not.

[Metrotyranno]

Any assistance please? Servers are not graphing the eth0 data, they are the same version as the zabbix server.

Hello Metrotyranno,

Have you tried something to ensure eth0 is the good interface to manage ?
Like a discovery rule, I mean maybe you have your network connectivity from eth1 et eth0 is just down

[Metrotyranno]

Yes, The command below shows that there is in fact traffic going on eth0, the graph just says eth0: 0.

~# zabbix_agentd -t "net.if.in[eth0]"
net.if.in[eth0] [u|157171693666]

Whilst other data is showing up fine:

No problems about your item config ?
Custom multiplier or something else ?

This is my agent config:

# This is a config file for the Zabbix agent daemon (Unix)
# To get more information about Zabbix, visit http://www.zabbix.com
PidFile=/var/run/zabbix/zabbix_agentd.pid
LogFile=/var/log/zabbix/zabbix_agentd.log

This is still an issue, The items have not been edited, it is a stock install.
