GoAccess is an open source real-time log analyzer and interactive viewer that runs in a terminal in *nix systems or through your browser.
It provides fast and valuable HTTP statistics for system administrators that require a visual server report on the fly.
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.
