ScanErrLog is a Python module that allows you to parse Apache error_log files and present their data in decreasing order of occurences of error messages. This is particularly useful if you want to quickly solve the most annoying problems Web visitors encounter on your site. You can use it directly from the command line, import it into another Python program and use the classes it defines, or use it as a CGI script. You can produce reports in HTML, PDF, XML, or Plain Text formats.
scanSquidLog quickly scans through Squid log files looking for lines whose URLs match any of those contained in a specified file. Matching lines are printed to standard output, and the main reason for using this program instead of standard utilities such as grep or awk is speed. Pattern matching for the URLs is not provided, but sub-domains, trailing path components, and case independence are automatically handled.
Squij is a Python script to analyse and help tune refresh_patterns in Squid (1.x and 2.x) configurations for freshness and efficiency.

StreamLog is a Perl script to automatically filter a compressed web server log as it streams via FTP. It figures out the most recent file and checks the modification date, and so is useful for running from cron. StreamLog saves only the records matching your web site, as opposed to your ISP's entire log file.
