Agent send wrong traffic data on eth0

[alexishida]

I used this configuration:

docker run \ -d \ --restart=always \ -p 10050:10050 \ --name=zabbix-agent \ --volume=/:/rootfs:ro \ --volume=/var/run:/var/run:rw \ --volume=/sys:/sys:ro \ --volume=/var/lib/docker/:/var/lib/docker:ro \ --env="ZABBIX_SERVER=" \ million12/zabbix-agent

and data on eth0 is wrong.

Ubuntu 14.04 Docker version 1.10.1, build 9e83765

Can you try with --privileged and let us know if that works?

[alexishida]

It's still not working :(

I had installed cadvisor for test and it works.

What version of Zabbix Server are you using? It was tested only on 2.4.x versions, not 3+

[alexishida]

Zabbix Server 3.0 all metrics works fine, only eth0 not work!

[pozgo]

I think it needs to be rebuild within zabbix 3 rather than 2. I'm pretty busy at the moment but if time allows I'll try to update it to version 3.x. Unless someone wants to do this and send us PR. :)

@alexishida image has been rebuild with zabbix agent 3.0.1

Hopefully, that will solve your issues.

docker run \ -d \ --privileged \ --restart=always \ -p 10050:10050 \ --name=zabbix-agent \ -v /proc:/data/proc \ -v /sys:/data/sys \ -v /dev:/data/dev \ -v /var/run/docker.sock:/var/run/docker.sock \ --env="ZABBIX_SERVER=ip" \ million12/zabbix-agent:3.0.1

This new agent still send wrong eth0 metrics :(

Same here with the million12/zabbix-agent:2.4.7. But I get this on CentOS systems only. Debian and Ubuntu ones does not have this problem.

The output is obviously not the same as on the host. This issue is probably SELinux-related.
