GoAccess – Open-source real-time log analyzer and interactive viewer

Why GoAccess? GoAccess was designed to be a fast, terminal-based log analyzer. Its core idea is to quickly analyze and view web server statistics in real time without needing to use your browser (great if you want to do a quick analysis of your access log via SSH, or if you simply love working in the terminal). It also serves as a practical tool for security monitoring, making it easy to spot suspicious activity, unusual traffic patterns, brute-force attempts, scanners, bots, and anomalous requests directly from your logs. While the terminal output is the default output, it has the capability to generate a complete, self-contained real-time HTML report (great for analytics, monitoring and data visualization), as well as a JSON, and CSV report. Key Features Fast, real-time (TUI + Web dashboard), millisecond/second updates, written in C Only ncurses as a dependency Nearly all web log formats (Apache, Nginx, Amazon S3, Elastic Load Balancing, CloudFront, Caddy, etc) Simply set the log format and run it against your log Beautiful terminal and bootstrap dashboards (Tailor GoAccess to suit your own color taste/schemes) and of course, Valgrind tested.
