The article provides a comprehensive guide on monitoring NGINX web servers using the Elastic Stack, focusing on the installation and configuration of Metricbeat and Filebeat to collect data, which is then stored in Elasticsearch and visualized with Kibana. Metricbeat is used to gather metrics related to server connections and client requests, while Filebeat collects access and error logs, allowing users to identify potential issues such as spikes in error logs or client requests that could indicate resource deletion or malicious activities like DDoS attacks. The guide gives step-by-step instructions for setting up Elasticsearch and configuring Metricbeat and Filebeat, including Autodiscover setups for containerized environments like Docker. It concludes with instructions on using Kibana to visualize the collected data and loading pre-configured NGINX dashboards for easier monitoring, while also encouraging users to explore different options and configurations within the Elastic Stack.
