Loading modules

[pl33g0r]

Hello!

I am trying to install zabbix module for docker (https://github.com/jangaraj/Zabbix-Docker-Monitoring). I was able to upload xml template without any issues. However, when I am trying to run Makefile script on zabbix server I am getting the following errors:

./Makefile

This is what happens when I ran Makefile script on the client

/usr/local/lib/zabbix/agent# ./Makefile
./Makefile: line 1: zabbix_module_docker:: command not found
zabbix_module_docker.c:20:20: fatal error: sysinc.h: No such file or directory
 #include "sysinc.h"
                    ^
compilation terminated.

I was reading documentation on modules and I have couple of questions:

1. It is mentioning that there is a dummy.so file, but I was not able to find it neither on server or client
2. At the same time I would like to know what it the full path for /src/modules
3. Is there a more easy to understand document that will explain how to add 3rd party modules?

Thanks in advance!

If you want to build module, then you need also Zabbix source code. Quick overview how to compile it:

cd ~
mkdir zabbix24
cd zabbix24
svn co svn://svn.zabbix.com/branches/2.4 .
./bootstrap.sh
./configure --enable-agent
mkdir src/modules/zabbix_module_docker
cd src/modules/zabbix_module_docker
wget https://raw.githubusercontent.com/jangaraj/Zabbix-Docker-Monitoring/master/src/modules/zabbix_module_docker/zabbix_module_docker.c
wget https://raw.githubusercontent.com/jangaraj/Zabbix-Docker-Monitoring/master/src/modules/zabbix_module_docker/Makefile
make

Final output will be zabbix_module_docker.so, which can be loaded by zabbix agent.

Check the latest doc (5.2.4 Building modules) for more details:

https://www.zabbix.com/documentation/2.4/manual/config/items/loadablemodules

Thx for feedback, I'll add info how to compile module to README.
BTW: compiled module is also available https://drone.io/github.com/jangaraj...dule_docker.so
