basic configuration for zabbix server in docker container monitoring its own host

[kr1p]

Hi,
Im running zabbix server in a docker container where port 10051 is open.
On the machine running the container i have installed zabbix-agent2 which is running and enabled as a service.
I can see the machine in my zabbix web frontend : when i click hosts i see the zabbix host and the ping is working on this host.
However i have a message
Code:
Get value from agent failed: cannot connect to [[127.0.0.1]:10050]: [111] Connection refused
I have tried to change the ip adress in /etc/zabbix/zabbix_agent2.conf but it is the same.

I ve tried to set up appropriately the docker container so that localhost adress (127.0.0.1) of the host is visible inside the docker container running the server (following this example : https://stackoverflow.com/questions/...gether-in-dock ) , but i still have the same issue with
a host with network interface as :

127.0.0.1:10050

I dont know how to troubleshoot this...Could you help me?

I ve also posted on stackoverflow a more precise post on my problem:
https://stackoverflow.com/questions/...e-zabbix-serve


I m running a dockerized version of zabbix server (centos 6.0) on my host. I m also running zabbix-agent2 on this host with configuration of server with ip adress of 127.0.0.1.

When i go into zabbix frontend web interface i get these error on the detected host:

When the ip is at default value 127.0.0.1:10050:

Get value from agent failed: cannot connect to [[127.0.0.1]:10050]: [111] Connection refused
When i change the default value to 172.17.0.1:10050 (the docker cant identify localhost of the host naturally) :

Get value from agent failed: ZBX_TCP_READ() failed: [104] Connection reset by peer
When i go to host and i ping or traceroute the host it works well. When i go to host and i try detect operating system i get the error

Cannot execute script. sh: sudo: command not found
What can i do to make the host work properly?

I have tried to check these posts : Access localhost from docker container (when i use 172.17.0.1).

I have tried to use network_mode: host but it conflicts with network being defined in the docker-compose.yml

I have tried this solution How to use the host network, and any other user-defined network together in Docker-Compose? but it doesnt work either

The port of the docker-compose is well defined and mapped (10051:10051)

Hello guys,

I'm new to Zabbix, and just trying it out. Looks like a very lot of people and companies using it across the world. I have found few videos on that, regarding setup, different features etc. But looks like this simple thing like monitoring host itself running docker (and even monitoring it with dockerized zabbix-agent) is not supported well. I have found few lines on a Github page about that, but it is not clear enough. So, even using mid-deep web search gives very poor results like this topic. Is it really so damn bad? Almost 2 years gone, but there is still no solution for this issue! Shocking
