I compiled the module as it says in the README.
On "OpenMediaVault" debian version 7.8
But when the zabbix agent starts I get an error, here is a debug level 4 log:
using configuration file: /usr/local/etc/zabbix_agentd.conf

Which version of Zabbix agent did you use? How did compile your Zabbix agent?

dedenker commented Sep 7, 2015

version 2.4 as your manual, just followed those steps.
Is there anyway to get more information of what the module is (not) doing?
The zabbix agent without the module works fine.

Makefile is including add_request_param function from Zabbix agent source code:

-I../../../src/libs/zbxsysinfo

add_request_param is available during compilation, because you don't have compilation error. But then you are executing some binary zabbix_agent(d) code and I'm curious about this binary code (this binary code has some issue). It can be package from (un)official repo, it can be different version (e.g. 1.8), it can be compiled locally, ....

So I need information about your Zabbix agent, not zabbix module. How did you install your Zabbix agent on your system and which version?

At the moment I can not investigate the problem because of network issues.
They promise to have it fixed within 8 hours! Anyway, I will give you the information tomorrow by the latest...so you know.

Okay, got the info:
zabbix_agent --version = Zabbix agent v2.4.0 (revision 48953)
zabbix_agentd --version = Zabbix Agent (daemon) v2.4.0 (revision 48953)

I compiled the zabbix agent as it stated in the manual (official wiki)
configure --enable-agent
make
make install

Is this any use?

No clue. Could you provide full commands/logs/outputs how did you checkout/compile module please? Please attach also your zabbix agent config, enable debugging and start agent - attach full startup logs +

cat /etc/debian_version
uname -a
whereis zabbix_agentd
ldd $(whereis zabbix_agentd)
ldd zabbix_module_docker.so

If you can, pls delete all Zabbix stuff (I see a few zabbix_agentds in different locations) on your server and execute these commands - it will compile module/agent with test config. It's user error from my point of view, but still I don't know how and what did you do. So please execute these commands and provide outputs from your console (yes, it can be huge but I need to see everything):

apt-get update
apt-get install -y wget autoconf automake gcc subversion make pkg-config
cd ~
mkdir zabbix24
cd zabbix24
svn co svn://svn.zabbix.com/branches/2.4 .
./bootstrap.sh
./configure --enable-agent
make
make install
mkdir src/modules/zabbix_module_docker
cd src/modules/zabbix_module_docker
wget https://raw.githubusercontent.com/monitoringartist/Zabbix-Docker-Monitoring/master/src/modules/zabbix_module_docker/zabbix_module_docker.c
wget https://raw.githubusercontent.com/monitoringartist/Zabbix-Docker-Monitoring/master/src/modules/zabbix_module_docker/Makefile
make
cp zabbix_module_docker.so /tmp
chmod 777 /tmp/zabbix_module_docker.so
touch /tmp/testzabbixconfig.conf
chmod 777 /tmp/testzabbixconfig.conf
echo "Server=127.0.0.1" >> /tmp/testzabbixconfig.conf
echo "LoadModulePath=/tmp" >> /tmp/testzabbixconfig.conf
echo "DebugLevel=4" >> /tmp/testzabbixconfig.conf
echo "LoadModule=zabbix_module_docker.so" >> /tmp/testzabbixconfig.conf
echo "AllowRoot=1" >> /tmp/testzabbixconfig.conf
echo "LogFile=/tmp/zbx.log" >>  /tmp/testzabbixconfig.conf
/usr/local/sbin/zabbix_agentd -c /tmp/testzabbixconfig.conf
sleep 60
cat /tmp/zbx.log

Okay, indeed there was a lot of text.
So I did setup a similar server (OS) and did everything you said.
And the module did work, I could only not really test as the machine doesn't had the production docker environment!
But the problem is with the machine, not your source.
I will investigate if it is the zabbix agent or something else.

Cool, I'm closing this issue, because it's not related to module. Please use Zabbix forum for your problem.
