ngxtop parses your Nginx access log and outputs real-time metrics. It's designed for quick troubleshooting and monitoring, functioning similarly to the top command. ngxtop defaults to Nginx logs but is configurable for other log formats, enabling analysis of Apache, Caddy, and other web server logs. It can be a helpful alternative to long-running monitoring systems.
ngxtop's flexibility extends beyond Nginx, supporting various log formats like Apache and Caddy. The ability to filter data, specify custom log formats, and perform aggregations enhances its adaptability. Detailed statistics are available, including request paths and HTTP referers, for granular insights. It supports filtering, pre-filtering, and http_referer display.

ngxtop is actively maintained, with recent commits indicating ongoing development and support. A good number of stars and forks suggest a decent level of community interest. Comprehensive documentation and several examples are available, and the project has a good history of releases, contributing to its reliability.
ngxtop benefits system administrators and developers by providing real-time insights into Nginx server performance and behavior. It's useful for monitoring server load, identifying potential issues, and diagnosing problems. Compared to manual log analysis or static monitoring tools, ngxtop offers a dynamic, immediate view of server activity.
