unable to set up docker monitoring using zabbix 5.0

[lastwon]

I have recently upgraded to Zabbix 5.0.1 to monitor docker and installed zabbix-agent on a docker server. However, I am into a bit of an issue with errors as following:

Zabbix Version: 5.0.1
Zabbix server IP: 192.168.0.60
Docker server IP: 192.168.0.65

/etc/zabbix/zabbix_agentd.conf from docker server:

Server=192.168.0.60
ServerActive=192.168.0.60
Hostname=docker

[root@docker:/root]# zabbix_get -s 127.0.0.1 -k docker.info

Please let me know if any additional information is required

Hey, lastwon!
You will get error "ZBX_NOTSUPPORTED: Cannot fetch data." if your agent can not access docker socket (/var/run/docker.sock usually). For example you need to add user you're running agent under to "docker" group or run agent as a root. Try to raise agent logging level and check log output, there could be something about either denied access to socker or that agent can not find it (in that case you'll need to change default path in agent config). I had a similar issue, but i was running agent in a container itself.

Thank you @visiandy! It worked like a charm.
