From web server logs to metrics: Visualizing NGINX logs with Prometheus and Grafana
When users start reporting slow responses or intermittent errors from your web applications, your first go-to is your web server logs. But did you know those same logs can provide more than just troubleshooting clues? When analyzed with the right tools, they give system administrators and DevOps teams real-time visibility into your web environment, enabling them to monitor web servers proactively, rather than reactively.
In this post, we’re going to show you how you can uncover web server performance issues and potential attacks early on by collecting NGINX access logs with NXLog Agent, transforming them into Prometheus metrics, and visualizing them with Grafana.
