A Zabbix agent is a program that runs on a remote machine that needs to be monitored through the Zabbix server. The agent collects the data on the remote server and send back to Zabbix server when requested. Zabbix agent must be installed on all the remote systems that need to be monitor through the Zabbix server.
There are two types of checks:
- Passive Check – Zabbix Agent sent data to server on their request.
- Active Check – Zabbix Agent sends data periodically to server.
In this article, we will learn how to install the Zabbix agent on OpenSUSE Leap 15.3 Server.

1. Ensure that the server packages are up to date
Before proceeding, let us make sure that our server packages are up to date with this command:
sudo zypper refresh sudo zypper update -y
Let us also install some common packages that we will need
sudo zypper install -y vim
2. Install the Zabbix Agent
The Zabbix agent packages are not available under the default OpenSUSE repositories. We will need to configure the Zabbix repository in our system before installing the agent.
The latest Zabbix version as at the writing of this article is Zabbix version 5.4. Install the repository configuration package. This package contains yum (software package manager) configuration files.
sudo rpm -Uvh --nosignature https://repo.zabbix.com/zabbix/6.0/sles/15/x86_64/zabbix-release-6.0-1.sles15.noarch.rpm sudo zypper --gpg-auto-import-keys refresh 'Zabbix Official Repository'
Once the repository is installed, we can install the agent. Use this command:
sudo zypper install -y zabbix-agent
Confirm the software version installed:
~> rpm -qi zabbix-agent Name : zabbix-agent Version : 6.0.0 Release : 1.sles15 Architecture: x86_64 Install Date: Wed Feb 23 14:57:24 2022 Group : Applications/Internet Size : 2185451 License : GPLv2+ Signature : RSA/SHA512, Mon Feb 14 14:59:16 2022, Key ID 082ab56ba14fe591 Source RPM : zabbix-6.0.0-1.sles15.src.rpm Build Date : Mon Feb 14 14:26:21 2022 Build Host : builds.zabbix.lan Relocations : (not relocatable) URL : http://www.zabbix.com/ Summary : Zabbix Agent Description : Old implementation of zabbix agent. To be installed on monitored systems. Distribution: (none)
3. Configure Zabbix Agent
Now, you need to configure the Agent service to allow Zabbix server requests. We will also update the Hostname so we know which server we configured the agent on. Edit the Zabbix agent configuration file by adding the Zabbix server IP.
sudo vim /etc/zabbix/zabbix_agentd.conf
Add this content:
Server=10.70.5.218 ServerActive=10.70.5.218 Hostname=dev-susesrv
In the “
Server” and “
ServerActive” parameters put the IP address of your Zabbix server or proxy!
4.Adjust Firewall for Zabbix
If you have firewall installed and enabled, you will need to allow the Zabbix ports 10050 and 10051. and HTTP service through the firewall. You can allow them with the following command:
sudo firewall-cmd --permanent --add-port=10050/tcp sudo firewall-cmd --reload
5. Start and enable the Zabbix agent
We can now start the agent. Use this command to start:
sudo systemctl start zabbix-agent
Check the status to confirm that it is started.
~> sudo systemctl status zabbix-agent ● zabbix-agent.service - Zabbix Agent Loaded: loaded (/usr/lib/systemd/system/zabbix-agent.service; disabled; vendor preset: disabled) Active: active (running) since Wed 2022-02-23 14:59:07 UTC; 4s ago Process: 17358 ExecStart=/usr/sbin/zabbix_agentd -c $CONFFILE (code=exited, status=0/SUCCESS) Main PID: 17360 (zabbix_agentd) Tasks: 6 (limit: 4587) CGroup: /system.slice/zabbix-agent.service ├─17360 /usr/sbin/zabbix_agentd -c /etc/zabbix/zabbix_agentd.conf ├─17361 /usr/sbin/zabbix_agentd: collector [idle 1 sec] ├─17362 /usr/sbin/zabbix_agentd: listener #1 [waiting for connection] ├─17363 /usr/sbin/zabbix_agentd: listener #2 [waiting for connection] ├─17364 /usr/sbin/zabbix_agentd: listener #3 [waiting for connection] └─17365 /usr/sbin/zabbix_agentd: active checks #1 [idle 1 sec] Feb 23 14:59:07 opensusesrv.citizix.com systemd: Starting Zabbix Agent...

Feb 23 14:59:07 opensusesrv.citizix.com systemd: Started Zabbix Agent.
From the above output, we can confirm that the agent is running. To enable the agent to start on boot, use this command:
sudo systemctl enable zabbix-agent
That is it! You have successfully installed Zabbix Agent on your OpenSUSE Leap 15.3. You can now proceed to add host in Zabbix server to be monitored. Checkout this guide How to Add Host in Zabbix Server to Monitor.
