====== Display Public IP Address of Remote Client in Grafana via Zabbix ======

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.

===== Step 1: Create the Zabbix UserParameter =====

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.

<code>
\\10.241.26.108\c$\Program Files\Zabbix Agent\zabbix_agentd.d\wan.conf
</code>

In the file, add the following line:

<code>
UserParameter=address.WAN,powershell -File C:\temp\get_wan_IP.ps1
</code>

===== Step 2: PowerShell Script to Get Public IP Address =====

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

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

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

===== Step 3: Create the Zabbix Item =====

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.

===== Step 4: Display in Grafana =====

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.

===== Conclusion =====

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