Logstalgia (also known as ApachePong) is a very powerful and handy app. It is a website access log visualization tool. It is an extremely useful tool to give you look at your web server traffic. I often use this kind of software to justify and convince my clients and/or boss that we need more servers to handle traffic. It streams Apache / Lighttpd / Nginx web-server access logs as a pong-like battle between the web server and a never ending torrent of requests.
The HTTP 2xx class of status codes indicates the action requested by the client was received, and processed successfully. HTTP/1.1 200 OK is the standard response for successful HTTP requests. When you type www.cyberciti.biz in the browser you will get this status code. The HTTP/1.1 206 status code allows the client to grab only part of the resource by sending a range header. This is useful for:
- Understanding http headers and protocol.
- Troubleshooting network problems.
- Troubleshooting large download problems.
- Troubleshooting CDN and origin HTTP server problems.
- Test resuming interrupted downloads using tools like lftp or wget or telnet.
- Test and split a large file size into multiple simultaneous streams i.e. download a large file in parts.
