Logstalgia is a visualization tool that visualize web access logs as a game simulation (as a pong like battle game between web server and requests). Requests are appeared as colored balls and travel across the screen to reach requested location. The colored ball hits the paddle if it is a successful request otherwise it misses (for e.g. if it is an error) Requirements: > Its works with OpenGL (Open graphic Library) and need an accelerated 3D display to visualize > A web server with logs such as Apache, Lighttpd, Nginx …
