Visitors, a fast web log analyzer

今天在网上发现一个快速处理web server日志文件的免费工具vistors。它与以前用过用perl写的开源软件awstats相比，没有那么强大，却比较安全。自己以前就因为awstats的漏洞吃过亏，web server被人hack过。

visitors的特点如下

• No installation required, can process up to 150,000 lines of log entries per second in fast computers (20MB/s with my log files average length).


• Designed to be executed by the command line, output html and text reports. The text report can be used in pipe to less to check web stats from ssh.


• Support for real time statistics with the Visitors Stream Mode introduced with version 0.3.


• To specify the log format is not needed at all. Works out of box with apache and most other web servers with a standard log format (see the documentation for more information on the format).


• It's a portable C program, can be compiled on many different systems. Binaries for Windows systems are in the Download section of this page.


• The produced html report doesn't contain images or external CSS, is self-contained, you can send it by email to users.


• Visitors is free software (and of course, freeware), under the terms of the GPL license. You don't need to pay to use it. Visitors is supported, if you want a custom version made directly by the original author for a modest price, contact me at antirez (at) invece.org. ISPs may take advantage of the high processing speed.
