14 # - LOG_LEVEL_CGI, LOG_LEVEL_ERROR, LOG_LEVEL_WRITE content highlighting
15 # - create fancy statistics
16 # - grep through Privoxy sources to find unsupported log messages
17 # - hunt down substitutions that match content from variables which
18 # can contain stuff like ()?'[]
19 # - replace $h{'foo'} with h('foo') where possible
20 # - hunt down XXX comments instead of just creating them
21 # - add example log lines for every regex and mark them up for
23 # - Handle incomplete input without Perl warning about undefined variables.
24 # - Use generic highlighting function that takes a regex and the
26 # - Add --compress and --decompress options.

2575 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
2579 B<privoxy-log-parser> [B<--html-output>]
2580 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--statistics>]
2581 [B<--shorten-thread-ids>] [B<--show-ineffective-filters>]
2582 [B<--url-statistics-threshold>] [B<--version>]
2586 B<privoxy-log-parser> reads Privoxy log messages and
2588 - syntax-highlights recognized lines,
2590 - reformats some of them for easier comprehension,
2592 - filters out less useful messages, and
2594 - (in some cases) calculates additional information,
2595 like the compression ratio or how a filter affected
2598 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
2599 without getting confused by the resulting amount of output. For example for
2600 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
2601 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
2602 will hide the "filter foo caused 0 hits" message.
2606 [B<--host-statistics-threshold>] Only show the request count for a host
2607 if it's above or equal to the given threshold. If the threshold is 0, host
2608 statistics are disabled.
2610 [B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
2611 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
2612 This option is only intended to make embedding log excerpts in web pages easier.
2613 It does not escape any input!
2615 [B<--no-msecs>] Don't expect milisecond resolution
2617 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
2618 the filtered output is piped into less in which case the ANSI control
2619 codes don't work, or if the terminal itself doesn't support the control
2622 [B<--shorten-thread-ids>] Shorten the thread ids to a three-digit decimal number.
2623 Note that the mapping from thread ids to shortened ids is created at run-time
2624 and thus varies with the input.
2626 [B<--show-ineffective-filters>] Don't suppress log lines for filters
2627 that didn't modify the content.
2629 [B<--show-complete-request-distribution>] Show the complete client request
2630 distribution in the B<--statistics> output. Without this option only the
2631 ten most common numbers are shown.
2633 [B<--statistics>] Gather various statistics instead of syntax highlighting
2634 log messages. This is an experimental feature, if the results look wrong
2635 they very well might be. Also note that the results are pretty much guaranteed
2636 to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.
2638 [B<--strict-checks>] When generating statistics, look more careful at the
2639 input data and abort if it is unexpected, even if it doesn't affect the
2640 results. Significantly slows the parsing down and is not expected to catch
2641 any problems that matter.
2642 When highlighting, print warnings in case of unknown messages which can't be
2643 properly highlighted.
2645 [B<--unbreak-lines-only>] Tries to fix lines that got messed up by a broken or
2646 interestingly configured mail client and thus are no longer recognized properly.
2647 Only fixes some breakage, but may be good enough or at least better than nothing.
2648 Doesn't do anything else, so you probably want to pipe the output into
2649 B<privoxy-log-parser> again.
2651 [B<--url-statistics-threshold>] Only show the request count for a resource
2652 if it's above or equal to the given threshold. If the threshold is 0, URL
2653 statistics are disabled.
2655 [B<--version>] Print version and exit.
2659 To monitor a log file:
2661 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
2663 Replace '-F' with '-f' if your tail implementation lacks '-F' support
2664 or if the log won't get rotated anyway. The log file location depends
2665 on your system (Doh!).
2667 To monitor Privoxy without having it write to a log file:
2669 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
2671 Again, the config file location depends on your system. Output redirection
2672 depends on your shell, the above works with bourne shells.
2674 To read a processed Privoxy log file from top to bottom, letting the content
2675 scroll by slightly faster than you can read:
2677 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
2679 This is probably only useful to fill screens in the background of haxor movies.
2683 Syntax highlighting with ANSI escape sequences will look strange
2684 if your background color isn't black.
2686 Some messages aren't recognized yet and will not be fully highlighted.
2688 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
2689 using earlier Privoxy versions will probably result in an increased amount
2690 of unrecognized log lines.
2692 Privoxy's log files tend to be rather large. If you use HTML
2693 highlighting some browsers can't handle them, get confused and
2694 will eventually crash because of segmentation faults or unexpected
2695 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
2700 Many settings can't be controlled through command line options yet.
