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.

2981 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
2985 B<privoxy-log-parser> [B<--detect-inactivity>] [B<--inactivity-threshold msecs>]
2987 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--statistics>]
2988 [B<--shorten-thread-ids>] [B<--show-ineffective-filters>]
2989 [B<--url-statistics-threshold>] [B<--version>]
2993 B<privoxy-log-parser> reads Privoxy log messages and
2995 - syntax-highlights recognized lines,
2997 - reformats some of them for easier comprehension,
2999 - filters out less useful messages, and
3001 - (in some cases) calculates additional information,
3002 like the compression ratio or how a filter affected
3005 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
3006 without getting confused by the resulting amount of output. For example for
3007 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
3008 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
3009 will hide the "filter foo caused 0 hits" message.
3013 [B<--detect-inactivity>] Instead of syntax highlighting, detect periods
3014 of log inactivity of more than the amount of milliseconds specified with
3015 the B<--inactivity-threshold> option. Mainly useful for debugging.
3017 [B<--host-statistics-threshold>] Only show the request count for a host
3018 if it's above or equal to the given threshold. If the threshold is 0, host
3019 statistics are disabled.
3021 [B<--html-output>] Use HTML and CSS when syntax highlighting. If this option is
3022 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
3023 This option is only intended to make embedding log excerpts in web pages easier.
3024 It does not escape any input!
3026 [B<--inactivity-threshold msecs>] Specifies the number of milliseconds between
3027 log messages to consider inactivity when running in [B<--detect-inactivity>]
3030 [B<--keep-date>] Don't remove the date when printing highlighted log messages.
3031 Useful when parsing multiple log files at once.
3033 [B<--no-msecs>] Don't expect millisecond resolution
3035 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
3036 the filtered output is piped into less in which case the ANSI control
3037 codes don't work, or if the terminal itself doesn't support the control
3040 [B<--passed-request-statistics-threshold>] Only show the request count for
3041 a passed requests if it's above or equal to the given threshold. If the
3042 threshold is 0, passed request statistics are disabled.
3044 [B<--shorten-thread-ids>] Shorten the thread ids to a three-digit decimal number.
3045 Note that the mapping from thread ids to shortened ids is created at run-time
3046 and thus varies with the input.
3048 [B<--show-ineffective-filters>] Don't suppress log lines for filters
3049 that didn't modify the content.
3051 [B<--show-complete-request-distribution>] Show the complete client request
3052 distribution in the B<--statistics> output. Without this option only the
3053 ten most common numbers are shown.
3055 [B<--statistics>] Gather various statistics instead of syntax highlighting
3056 log messages. This is an experimental feature, if the results look wrong
3057 they very well might be. Also note that the results are pretty much guaranteed
3058 to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.
3060 [B<--strict-checks>] When generating statistics, look more careful at the
3061 input data and abort if it is unexpected, even if it doesn't affect the
3062 results. Significantly slows the parsing down and is not expected to catch
3063 any problems that matter.
3064 When highlighting, print warnings in case of unknown messages which can't be
3065 properly highlighted.
3067 [B<--unbreak-lines-only>] Tries to fix lines that got messed up by a broken or
3068 interestingly configured mail client and thus are no longer recognized properly.
3069 Only fixes some breakage, but may be good enough or at least better than nothing.
3070 Doesn't do anything else, so you probably want to pipe the output into
3071 B<privoxy-log-parser> again.
3073 [B<--url-statistics-threshold>] Only show the request count for a resource
3074 if it's above or equal to the given threshold. If the threshold is 0, URL
3075 statistics are disabled.
3077 [B<--version>] Print version and exit.
3081 To monitor a log file:
3083 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
3085 Replace '-F' with '-f' if your tail implementation lacks '-F' support
3086 or if the log won't get rotated anyway. The log file location depends
3087 on your system (Doh!).
3089 To monitor Privoxy without having it write to a log file:
3091 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
3093 Again, the config file location depends on your system. Output redirection
3094 depends on your shell, the above works with bourne shells.
3096 To read a processed Privoxy log file from top to bottom, letting the content
3097 scroll by slightly faster than you can read:
3099 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
3101 This is probably only useful to fill screens in the background of haxor movies.
3105 Syntax highlighting with ANSI escape sequences will look strange
3106 if your background color isn't black.
3108 Some messages aren't recognized yet and will not be fully highlighted.
3110 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
3111 using earlier Privoxy versions will probably result in an increased amount
3112 of unrecognized log lines.
3114 Privoxy's log files tend to be rather large. If you use HTML
3115 highlighting some browsers can't handle them, get confused and
3116 will eventually crash because of segmentation faults or unexpected
3117 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
3122 Many settings can't be controlled through command line options yet.
