This article outlines a complete solution for monitoring Nginx access logs using Filebeat and Zabbix. It covers parsing access_log entries, setting up alerts for 5xx error spikes, detecting slow requests, and automatically blocking anomalous IPs. The approach is production-ready and can be adapted to various infrastructure setups. For DevOps teams, this provides a cost-effective alternative to commercial monitoring tools, leveraging open-source components. The guide is detailed but focuses on practical implementation rather than theory, making it a useful reference for engineers maintaining high-traffic web services.
