This guide explains how to display the public IP address of a remote client in Grafana using Zabbix. The client updates its status using the Zabbix agent, and we'll utilize a PowerShell script to fetch the public IP address.

First, create a configuration file for the Zabbix agent on the remote client. This file will define a UserParameter that Zabbix will use to execute a PowerShell script and retrieve the public IP address.

\\10.241.26.108\c$\Program Files\Zabbix Agent\zabbix_agentd.d\wan.conf

In the file, add the following line:

UserParameter=address.WAN,powershell -File C:\temp\get_wan_IP.ps1

Next, create the PowerShell script that fetches the public IP address. Save it in `C:\temp\get_wan_IP.ps1` on the remote client.

$wc = New-Object System.Net.WebClient
$wc.DownloadString("http://ifconfig.me/ip")

This script downloads the public IP address from `ifconfig.me`.

In Zabbix, create a new item for the client to fetch the public IP address.

• Go to Configuration > Templates.
• Search for the template Windows by Zabbix agent.
• Click on Items and create a new item.

Use the following parameters:

• Name: WAN Public IP Address
• Key: address.WAN
• Type: Text
• Tags: network:publicAddress

Save the item.

Finally, we will display the public IP address in Grafana.

• Open Grafana and add a new Visualization.
• Select Zabbix as the data source.
• Choose Query Type as `Text`.
• Use the item tag (e.g., `network:publicAddress`) to filter the correct item.

Since the item data type is text, Grafana will display it as a text field.

By following these steps, you can monitor and display the public IP address of a remote client using Zabbix and Grafana.
