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.

3017 [B<--url-statistics-threshold>] [B<--version>]
3021 B<privoxy-log-parser> reads Privoxy log messages and
3023 - syntax-highlights recognized lines,
3025 - reformats some of them for easier comprehension,
3027 - filters out less useful messages, and
3029 - (in some cases) calculates additional information,
3030 like the compression ratio or how a filter affected
3033 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
3034 without getting confused by the resulting amount of output. For example for
3035 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
3036 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
3037 will hide the "filter foo caused 0 hits" message.
3041 [B<--detect-inactivity>] Instead of syntax highlighting, detect periods
3042 of log inactivity of more than the amount of milliseconds specified with
3043 the B<--inactivity-threshold> option. Mainly useful for debugging.
3045 [B<--host-statistics-threshold>] Only show the request count for a host
3046 if it's above or equal to the given threshold. If the threshold is 0, host
3047 statistics are disabled.
3049 [B<--html-output>] Use HTML and CSS when syntax highlighting. If this option is
3050 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
3051 This option is only intended to make embedding log excerpts in web pages easier.
3052 It does not escape any input!
3054 [B<--inactivity-threshold msecs>] Specifies the number of milliseconds between
3055 log messages to consider inactivity when running in [B<--detect-inactivity>]
3058 [B<--keep-date>] Don't remove the date when printing highlighted log messages.
3059 Useful when parsing multiple log files at once.
3061 [B<--no-msecs>] Don't expect millisecond resolution
3063 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
3064 the filtered output is piped into less in which case the ANSI control
3065 codes don't work, or if the terminal itself doesn't support the control
3068 [B<--passed-request-statistics-threshold>] Only show the request count for
3069 a passed requests if it's above or equal to the given threshold. If the
3070 threshold is 0, passed request statistics are disabled.
3072 [B<--shorten-thread-ids>] Shorten the thread ids to a three-digit decimal number.
3073 Note that the mapping from thread ids to shortened ids is created at run-time
3074 and thus varies with the input.
3076 [B<--show-ineffective-filters>] Don't suppress log lines for filters
3077 that didn't modify the content.
3079 [B<--show-complete-request-distribution>] Show the complete client request
3080 distribution in the B<--statistics> output. Without this option only the
3081 ten most common numbers are shown.
3083 [B<--statistics>] Gather various statistics instead of syntax highlighting
3084 log messages. This is an experimental feature, if the results look wrong
3085 they very well might be. Also note that the results are pretty much guaranteed
3086 to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.
3088 [B<--strict-checks>] When generating statistics, look more careful at the
3089 input data and abort if it is unexpected, even if it doesn't affect the
3090 results. Significantly slows the parsing down and is not expected to catch
3091 any problems that matter.
3092 When highlighting, print warnings in case of unknown messages which can't be
3093 properly highlighted.
3095 [B<--unbreak-lines-only>] Tries to fix lines that got messed up by a broken or
3096 interestingly configured mail client and thus are no longer recognized properly.
3097 Only fixes some breakage, but may be good enough or at least better than nothing.
3098 Doesn't do anything else, so you probably want to pipe the output into
3099 B<privoxy-log-parser> again.
3101 [B<--url-statistics-threshold>] Only show the request count for a resource
3102 if it's above or equal to the given threshold. If the threshold is 0, URL
3103 statistics are disabled.
3105 [B<--version>] Print version and exit.
3109 To monitor a log file:
3111 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
3113 Replace '-F' with '-f' if your tail implementation lacks '-F' support
3114 or if the log won't get rotated anyway. The log file location depends
3115 on your system (Doh!).
3117 To monitor Privoxy without having it write to a log file:
3119 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
3121 Again, the config file location depends on your system. Output redirection
3122 depends on your shell, the above works with bourne shells.
3124 To read a processed Privoxy log file from top to bottom, letting the content
3125 scroll by slightly faster than you can read:
3127 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
3129 This is probably only useful to fill screens in the background of haxor movies.
3133 Syntax highlighting with ANSI escape sequences will look strange
3134 if your background color isn't black.
3136 Some messages aren't recognized yet and will not be fully highlighted.
3138 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
3139 using earlier Privoxy versions will probably result in an increased amount
3140 of unrecognized log lines.
3142 Privoxy's log files tend to be rather large. If you use HTML
3143 highlighting some browsers can't handle them, get confused and
3144 will eventually crash because of segmentation faults or unexpected
3145 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
3150 Many settings can't be controlled through command line options yet.
