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.

2913 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
2917 B<privoxy-log-parser> [B<--detect-inactivity>] [B<--inactivity-threshold msecs>]
2919 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--statistics>]
2920 [B<--shorten-thread-ids>] [B<--show-ineffective-filters>]
2921 [B<--url-statistics-threshold>] [B<--version>]
2925 B<privoxy-log-parser> reads Privoxy log messages and
2927 - syntax-highlights recognized lines,
2929 - reformats some of them for easier comprehension,
2931 - filters out less useful messages, and
2933 - (in some cases) calculates additional information,
2934 like the compression ratio or how a filter affected
2937 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
2938 without getting confused by the resulting amount of output. For example for
2939 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
2940 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
2941 will hide the "filter foo caused 0 hits" message.
2945 [B<--detect-inactivity>] Instead of syntax highlighting, detect inactivities
2946 of more than B<inactivity-threshold> miliseconds. Mainly useful for debugging.
2948 [B<--host-statistics-threshold>] Only show the request count for a host
2949 if it's above or equal to the given threshold. If the threshold is 0, host
2950 statistics are disabled.
2952 [B<--html-output>] Use HTML and CSS when syntax highlighting. If this option is
2953 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
2954 This option is only intended to make embedding log excerpts in web pages easier.
2955 It does not escape any input!
2957 [B<--inactivity-threshold>] Specifies the number of miliseconds between log
2958 messages to consider inactivity when running in [B<--detect-inactivity>] mode.
2960 [B<--keep-date>] Don't remove the date when printing highlighted log messages.
2961 Useful when parsing multiple log files at once.
2963 [B<--no-msecs>] Don't expect millisecond resolution
2965 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
2966 the filtered output is piped into less in which case the ANSI control
2967 codes don't work, or if the terminal itself doesn't support the control
2970 [B<--shorten-thread-ids>] Shorten the thread ids to a three-digit decimal number.
2971 Note that the mapping from thread ids to shortened ids is created at run-time
2972 and thus varies with the input.
2974 [B<--show-ineffective-filters>] Don't suppress log lines for filters
2975 that didn't modify the content.
2977 [B<--show-complete-request-distribution>] Show the complete client request
2978 distribution in the B<--statistics> output. Without this option only the
2979 ten most common numbers are shown.
2981 [B<--statistics>] Gather various statistics instead of syntax highlighting
2982 log messages. This is an experimental feature, if the results look wrong
2983 they very well might be. Also note that the results are pretty much guaranteed
2984 to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.
2986 [B<--strict-checks>] When generating statistics, look more careful at the
2987 input data and abort if it is unexpected, even if it doesn't affect the
2988 results. Significantly slows the parsing down and is not expected to catch
2989 any problems that matter.
2990 When highlighting, print warnings in case of unknown messages which can't be
2991 properly highlighted.
2993 [B<--unbreak-lines-only>] Tries to fix lines that got messed up by a broken or
2994 interestingly configured mail client and thus are no longer recognized properly.
2995 Only fixes some breakage, but may be good enough or at least better than nothing.
2996 Doesn't do anything else, so you probably want to pipe the output into
2997 B<privoxy-log-parser> again.
2999 [B<--url-statistics-threshold>] Only show the request count for a resource
3000 if it's above or equal to the given threshold. If the threshold is 0, URL
3001 statistics are disabled.
3003 [B<--version>] Print version and exit.
3007 To monitor a log file:
3009 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
3011 Replace '-F' with '-f' if your tail implementation lacks '-F' support
3012 or if the log won't get rotated anyway. The log file location depends
3013 on your system (Doh!).
3015 To monitor Privoxy without having it write to a log file:
3017 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
3019 Again, the config file location depends on your system. Output redirection
3020 depends on your shell, the above works with bourne shells.
3022 To read a processed Privoxy log file from top to bottom, letting the content
3023 scroll by slightly faster than you can read:
3025 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
3027 This is probably only useful to fill screens in the background of haxor movies.
3031 Syntax highlighting with ANSI escape sequences will look strange
3032 if your background color isn't black.
3034 Some messages aren't recognized yet and will not be fully highlighted.
3036 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
3037 using earlier Privoxy versions will probably result in an increased amount
3038 of unrecognized log lines.
3040 Privoxy's log files tend to be rather large. If you use HTML
3041 highlighting some browsers can't handle them, get confused and
3042 will eventually crash because of segmentation faults or unexpected
3043 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
3048 Many settings can't be controlled through command line options yet.
