Docker Monitoring Cannot Fetch Data

[Korshakov]

Hi Guys,

i've tried to install beta version of zabbix and everything runs smoothly as it should apart of docker monitoring. After a while i just get trigger for docker not available.

Server log:
154:20200502:214742.109 item "LS server:docker.containers" became not supported: Cannot fetch data.
153:20200502:214743.110 item "LS server:docker.data_usage" became not supported: Cannot fetch data.
155:20200502:214744.111 item "LS server:docker.images" became not supported: Cannot fetch data.
154:20200502:214745.111 item "LS server:docker.info" became not supported: Cannot fetch data.

Setup:
Centos 8 Server (bare metal - minimal install) with installed samba server and docker, nothing else.
Selinux disabled for testing purposes
Firewall ports open are 10050 tcp
Zabbix server is in docker container
Zabbix agent2 is running directly in centos

Whats known:
Zabbix server communicates without any issues with agent as I am getting all other info without problem.
I've tried to un-hashtag this line to see if it makes diffrence:
Plugins.Docker.Endpoint=unix:///var/run/docker.sock - no diffrence
I have portainer docker targeting same docker.sock path and it works just fine.
I have selected default docker template in docker host setup in web interface.
I have tried to run zabbix agent2 in docker as well to see if it would make a diffrence but no joy.

Am I missing out something?

Thank you

Does user zabbix on OS have permission to access /var/run/docker.sock?

see.
