Received empty response from Zabbix Agent installed on Zabbix Server

[dadokk3]

Hello. I have Zabbix Server installed on a virtual machine, lets call it 192.168.10.10. I also installed a Zabbix Agent on that machine.

In /etc/zabbix/zabbix_agentd.conf my Server parameter looks like this: Server = 127.0.0.1

In Configuration -> Hosts I click Create host, and put in the right hostname, group: Virtual machines,Agent interface: 192.168.10.10, and then template: Template OS Linux by Zabbix agent

After that I get error: Received empty response from Zabbix Agent at [192.168.10.10]. Assuming that agent dropped connection because of access permissions

What could be the issue?

If your Zabbix server is trying to contact the Zabbix agent on the 192.168.10.10, then you cannot generally use "Server=127.0.0.1" in the zabbix_agentd.conf. When the zabbix agent accepts the incoming connection (via the accept() networking call), it can examine the source address (the address of the remote side of the connection). That remote address will not be 127.0.0.1, it will be the 192.168.10.10 that you have assigned to your system.

If you want this one agent on the same system as your server to be monitored via the loopback address, then you must configure its agent interface in Zabbix using the 127.0.0.1 address.

tim.mooney thanks for response, but I have still trouble. Maybe I didn't understand correctly?

As you suggested I tried different variants of Server parameter in zabbix_agentd.conf and Agent interface in Zabbix frontend.

Agent interface=127.0.0.1 Server=192.168.10.10
ERROR: Get value from agent failed: cannot connect to [[127.0.0.1]:10050]: [111] Connection refused

I also tried 127.0.0.1 for Server parameter in zabbix_agentd.conf, but it returned the same error

I forgot to mention I am using docker image zabbix-appliance to host zabbix server.

[korayak88]

I have found the solution.
Yes, i use the docker container zabbix, me too
I installed zabbix-agent on operation system.

#nano /etc/zabbix/zabbix-agent.conf

You have to configure zabbix-agent
Server= Zabbix Container IP
ServerActive= Zabbix Container Ip
Hostname= Operation System Hostname

You can see Docker Container Which usage IP above command.

# docker inspect Containername
