How to Forward Windows 7 Logs to Nagios Log Server 2024R2: A Step-by-Step Guide

Reliable log collection and analysis are essential for effective IT infrastructure monitoring. This guide walks you through configuring a Windows 7 machine to capture and forward system logs to Nagios Log Server 2024R2 using NXLog Community Edition (CE).
