Detailed Guide — Installation of Zabbix Agent 7.0.12 LTS on Windows (64-bit)

This step-by-step guide is used to install Zabbix Agent 7 on Windows machines (64-bit), using the .msi installer with OpenSSL, even in environments with remote machines spread across Brazil. It does not require advanced technical knowledge.

Prerequisites

Before installing, you need to:

• Have administrator access to the machine

• Be connected to the internet

• Know the IP or domain of the Zabbix server

• Install Microsoft Visual C++ Redistributable 2015–2022 (x64)

Download the Zabbix Agent

1. Access: Zabbix Agent 2

2. Download the file: zabbix_agent2-7.0.12-windows-amd64-openssl.msi

3. Save it in a folder such as: C:\Instaladores\

Install the Microsoft Visual C++ Redistributable

1. Download here: Microsoft Visual C++ Redistributable

2. Run the installer: vc_redist.x64.exe

3. Click Install and wait

4. Restart the computer if prompted

Install the Zabbix Agent

• Screen 1 — Welcome

  • Click Next

• Screen 2 — License Terms

  • Check “I accept the terms…”

  • Click Next

• Screen 3 — Agent Configuration

  • Fill in carefully and click Next

Field	What to enter
Zabbix Server	The IP or domain of the Zabbix server (e.g., 200.175.10.25 or zabbix.yourcompany.com)
Agent Hostname	Unique name of the machine (e.g., FILIAL-SP-PC01)
Listen Port	10050 (default)
TLS/PSK/Certificados	Leave unchecked if not using advanced encryption

Understanding the Configuration of the 'Zabbix Server' Field

This field is ESSENTIAL: it defines who can connect to the agent and collect the data. If your company has:

• A central Zabbix Server (in the cloud or at headquarters)

• Several Windows machines

You must fill in the “Zabbix Server” field with the exact address of the server that will monitor the machines, for example:

zabbix.yourcompany.com
ou
200.100.150.200

Important:

• The Zabbix server must be able to reach this Windows machine via the internet or VPN

• The TCP port 10050 must be open in the machine’s firewall

• The name set in “Agent Hostname” must be unique and match the one used in the Zabbix Server

Useful tests:

ping zabbix.minhaempresa.com
telnet zabbix.minhaempresa.com 10051

Check if the service is running

1. Press Win + R, digite services.msc, and click OK

   • Or search in the taskbar for Run run.

2. Look for the service named: Zabbix Agent 2

3. It should have the status Running. If not:

• Right-click

• Select Start

Add the Host to the Zabbix Server

1. Access the Zabbix dashboard

2. Go to Monitoring → Hosts → Create Host

3. Fill in:

   • Hostname: same as the machine name

   • IP Address: machine’s IP

   • Agent interface: port 10050

4. Apply the template: Windows by Zabbix agent

5. Wait a few minutes for the data to start appearing

Common Problems and Solutions

Problem	Solution
Agent service does not start.	Install o vc_redist.x64.exe.
Host appears as “Unavailable”.	Allow port 10050 in the firewall.
Incorrect hostname.	Check if it matches the name configured on the machine.
TLS error or connection denied.	Uncheck encryption if it is not configured on the Zabbix Server.
No communication between the machine and the server.	Run ping and telnet tests to confirm access.

Conclusion

After following these steps:

• The Zabbix agent is installed.

• The Zabbix server can collect metrics from the machine.

• The machine is standardized and ready for centralized monitoring.

Tip: Use this guide in all branches to maintain a consistent installation standard.
