6 # A parser for Privoxy log messages. For incomplete documentation run
7 # perldoc privoxy-log-parser(.pl), for fancy screenshots see:
9 # https://www.fabiankeil.de/sourcecode/privoxy-log-parser/
12 # - LOG_LEVEL_CGI, LOG_LEVEL_ERROR, LOG_LEVEL_WRITE content highlighting
13 # - create fancy statistics
14 # - grep through Privoxy sources to find unsupported log messages
15 # - hunt down substitutions that match content from variables which
16 # can contain stuff like ()?'[]
17 # - replace $h{'foo'} with h('foo') where possible
18 # - hunt down XXX comments instead of just creating them
19 # - add example log lines for every regex and mark them up for
21 # - Handle incomplete input without Perl warning about undefined variables.
22 # - Use generic highlighting function that takes a regex and the
24 # - Add --compress and --decompress options.

2736 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
2740 B<privoxy-log-parser> [B<--html-output>]
2741 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--statistics>]
2742 [B<--shorten-thread-ids>] [B<--show-ineffective-filters>]
2743 [B<--url-statistics-threshold>] [B<--version>]
2747 B<privoxy-log-parser> reads Privoxy log messages and
2749 - syntax-highlights recognized lines,
2751 - reformats some of them for easier comprehension,
2753 - filters out less useful messages, and
2755 - (in some cases) calculates additional information,
2756 like the compression ratio or how a filter affected
2759 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
2760 without getting confused by the resulting amount of output. For example for
2761 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
2762 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
2763 will hide the "filter foo caused 0 hits" message.
2767 [B<--host-statistics-threshold>] Only show the request count for a host
2768 if it's above or equal to the given threshold. If the threshold is 0, host
2769 statistics are disabled.
2771 [B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
2772 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
2773 This option is only intended to make embedding log excerpts in web pages easier.
2774 It does not escape any input!
2776 [B<--keep-date>] Don't remove the date when printing highlighted log messages.
2777 Useful when parsing multiple log files at once.
2779 [B<--no-msecs>] Don't expect milisecond resolution
2781 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
2782 the filtered output is piped into less in which case the ANSI control
2783 codes don't work, or if the terminal itself doesn't support the control
2786 [B<--shorten-thread-ids>] Shorten the thread ids to a three-digit decimal number.
2787 Note that the mapping from thread ids to shortened ids is created at run-time
2788 and thus varies with the input.
2790 [B<--show-ineffective-filters>] Don't suppress log lines for filters
2791 that didn't modify the content.
2793 [B<--show-complete-request-distribution>] Show the complete client request
2794 distribution in the B<--statistics> output. Without this option only the
2795 ten most common numbers are shown.
2797 [B<--statistics>] Gather various statistics instead of syntax highlighting
2798 log messages. This is an experimental feature, if the results look wrong
2799 they very well might be. Also note that the results are pretty much guaranteed
2800 to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.
2802 [B<--strict-checks>] When generating statistics, look more careful at the
2803 input data and abort if it is unexpected, even if it doesn't affect the
2804 results. Significantly slows the parsing down and is not expected to catch
2805 any problems that matter.
2806 When highlighting, print warnings in case of unknown messages which can't be
2807 properly highlighted.
2809 [B<--unbreak-lines-only>] Tries to fix lines that got messed up by a broken or
2810 interestingly configured mail client and thus are no longer recognized properly.
2811 Only fixes some breakage, but may be good enough or at least better than nothing.
2812 Doesn't do anything else, so you probably want to pipe the output into
2813 B<privoxy-log-parser> again.
2815 [B<--url-statistics-threshold>] Only show the request count for a resource
2816 if it's above or equal to the given threshold. If the threshold is 0, URL
2817 statistics are disabled.
2819 [B<--version>] Print version and exit.
2823 To monitor a log file:
2825 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
2827 Replace '-F' with '-f' if your tail implementation lacks '-F' support
2828 or if the log won't get rotated anyway. The log file location depends
2829 on your system (Doh!).
2831 To monitor Privoxy without having it write to a log file:
2833 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
2835 Again, the config file location depends on your system. Output redirection
2836 depends on your shell, the above works with bourne shells.
2838 To read a processed Privoxy log file from top to bottom, letting the content
2839 scroll by slightly faster than you can read:
2841 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
2843 This is probably only useful to fill screens in the background of haxor movies.
2847 Syntax highlighting with ANSI escape sequences will look strange
2848 if your background color isn't black.
2850 Some messages aren't recognized yet and will not be fully highlighted.
2852 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
2853 using earlier Privoxy versions will probably result in an increased amount
2854 of unrecognized log lines.
2856 Privoxy's log files tend to be rather large. If you use HTML
2857 highlighting some browsers can't handle them, get confused and
2858 will eventually crash because of segmentation faults or unexpected
2859 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
2864 Many settings can't be controlled through command line options yet.
