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.

2614 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
2618 B<privoxy-log-parser> [B<--html-output>]
2619 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--statistics>]
2620 [B<--shorten-thread-ids>] [B<--show-ineffective-filters>]
2621 [B<--url-statistics-threshold>] [B<--version>]
2625 B<privoxy-log-parser> reads Privoxy log messages and
2627 - syntax-highlights recognized lines,
2629 - reformats some of them for easier comprehension,
2631 - filters out less useful messages, and
2633 - (in some cases) calculates additional information,
2634 like the compression ratio or how a filter affected
2637 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
2638 without getting confused by the resulting amount of output. For example for
2639 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
2640 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
2641 will hide the "filter foo caused 0 hits" message.
2645 [B<--host-statistics-threshold>] Only show the request count for a host
2646 if it's above or equal to the given threshold. If the threshold is 0, host
2647 statistics are disabled.
2649 [B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
2650 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
2651 This option is only intended to make embedding log excerpts in web pages easier.
2652 It does not escape any input!
2654 [B<--no-msecs>] Don't expect milisecond resolution
2656 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
2657 the filtered output is piped into less in which case the ANSI control
2658 codes don't work, or if the terminal itself doesn't support the control
2661 [B<--shorten-thread-ids>] Shorten the thread ids to a three-digit decimal number.
2662 Note that the mapping from thread ids to shortened ids is created at run-time
2663 and thus varies with the input.
2665 [B<--show-ineffective-filters>] Don't suppress log lines for filters
2666 that didn't modify the content.
2668 [B<--show-complete-request-distribution>] Show the complete client request
2669 distribution in the B<--statistics> output. Without this option only the
2670 ten most common numbers are shown.
2672 [B<--statistics>] Gather various statistics instead of syntax highlighting
2673 log messages. This is an experimental feature, if the results look wrong
2674 they very well might be. Also note that the results are pretty much guaranteed
2675 to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.
2677 [B<--strict-checks>] When generating statistics, look more careful at the
2678 input data and abort if it is unexpected, even if it doesn't affect the
2679 results. Significantly slows the parsing down and is not expected to catch
2680 any problems that matter.
2681 When highlighting, print warnings in case of unknown messages which can't be
2682 properly highlighted.
2684 [B<--unbreak-lines-only>] Tries to fix lines that got messed up by a broken or
2685 interestingly configured mail client and thus are no longer recognized properly.
2686 Only fixes some breakage, but may be good enough or at least better than nothing.
2687 Doesn't do anything else, so you probably want to pipe the output into
2688 B<privoxy-log-parser> again.
2690 [B<--url-statistics-threshold>] Only show the request count for a resource
2691 if it's above or equal to the given threshold. If the threshold is 0, URL
2692 statistics are disabled.
2694 [B<--version>] Print version and exit.
2698 To monitor a log file:
2700 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
2702 Replace '-F' with '-f' if your tail implementation lacks '-F' support
2703 or if the log won't get rotated anyway. The log file location depends
2704 on your system (Doh!).
2706 To monitor Privoxy without having it write to a log file:
2708 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
2710 Again, the config file location depends on your system. Output redirection
2711 depends on your shell, the above works with bourne shells.
2713 To read a processed Privoxy log file from top to bottom, letting the content
2714 scroll by slightly faster than you can read:
2716 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
2718 This is probably only useful to fill screens in the background of haxor movies.
2722 Syntax highlighting with ANSI escape sequences will look strange
2723 if your background color isn't black.
2725 Some messages aren't recognized yet and will not be fully highlighted.
2727 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
2728 using earlier Privoxy versions will probably result in an increased amount
2729 of unrecognized log lines.
2731 Privoxy's log files tend to be rather large. If you use HTML
2732 highlighting some browsers can't handle them, get confused and
2733 will eventually crash because of segmentation faults or unexpected
2734 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
2739 Many settings can't be controlled through command line options yet.
