Zabbix Agent not Reporting In

[droidus]

I've added an agent to my Zabbix server. I defined the Server= parameter in the config file, made sure to restart. Other than that change, I made no other changes to the config file. I can telnet from host to server, and server to host, on their respective ports. I added the host in the web ui. How do I get the host to show up and report in?

What version of Zabbix are you using? If you installed Zabbix agent on the same server where zabbix_sever is running with the official Zabbix package, you should be able to run it just by starting it without changing any settings. Make sure that the host named "Zabbix server" is registered on the web front end and that the host is enable.
Also, check if any error is output in the log of Zabbix server or Zabbix agent.

I found the versions differed. I pulled down zabbix_agent-5.0.5-linux-3.0-amd64-static.tar.gz. How do I install the agent from here though? My client is based off of Debian 10.4. My server is 5.0.5.

If you are using Debuan 10, you should use the official Zabbix package. Please install zabbix-agent package after registering the repository referring to the information in the following URL.

https://www.zabbix.com/download?zabbix=5.0&os_distribution=debian&os_version=10_buster&db=mysql&ws=apache

ex.

# wget https://repo.zabbix.com/zabbix/5.0/debian/pool/main/z/zabbix-release/zabbix-release_5.0-1+buster_all.deb
# dpkg -i zabbix-release_5.0-1+buster_all.deb
# apt update
# apt install zabbix-agent

Ok, that is installed, but it still is not showing up. Here is output from the log file:

Is the host registered on the web front end?
Is the interface setting of the host and the IP address or port number used by the agent matched or a combination that can be connected?
Also, have you linked the template to the host or registered the item?

I forgot to add a template, which fixed it.
