ngxtop

ngxtop is a command-line monitoring utility that provides real-time analytics for Nginx and similar web server access logs using a top-style interface. Instead of relying on heavy monitoring stacks, it parses live log streams and produces immediate insights into request rates, status codes, bandwidth usage, and endpoint activity. The tool is particularly useful for troubleshooting traffic spikes or diagnosing performance issues during active incidents. It automatically detects the access log location and format in many cases, enabling quick deployment with minimal configuration. Users can also customize queries, grouping logic, and filters to analyze specific traffic patterns or metrics. By combining the familiarity of the UNIX top paradigm with flexible log parsing, ngxtop offers a lightweight yet powerful approach to real-time web server observability.
