Cannot send proxy data to server at "zabbix-server"

[randomizedname]

Hi,
I'm using dockerized Zabbix 5.0.3. Currently I have ~30 servers connected, active checks only. Everything seems work fine, the data is received but I'm getting hundreds of such log lines per minute:

I must admit that I don't understand why I'm getting these. I don't use any zabbix proxy. Proxy is not configured in adminitration panel. Is it someting I should worry about?

This looks like mixed log of server and passive proxy. Are you running both on the same host, configured to write to the same log file?

Yes, this is /var/log/messages file on the docker host server. Zabbix is running as a docker container on this server. Zabbix containers are composed and started from this docker-compose file https://github.com/zabbix/zabbix-doc...ql_latest.yaml .I cannot see anything about log configuration in this file so I don't know how it works.

Maybe you have both server and proxy processes running? Could you confirm with

pgrep -a zabbix

[DmitryL]

Proxy name in proxy conf does not match with proxy name in the frontend.

[randomizedname]

I've deleted every container with "proxy" in its name from docker-compose file. Now it's okay

Thank you for your answer, it also solved my problem.

Hello im new here in this Forum. I installed a Zabbix-Proxy and he should send the data to two zabbix-monitors/servers. One of the two Zabbix-monitor/server always does not recognize the agents. Can someone help me?
