2038 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
2042 B<privoxy-log-parser> [B<--accept-unknown-messages>] [B<--html-output>]
2043 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--show-ineffective-filters>]
2048 B<privoxy-log-parser> reads Privoxy log messages and
2050 - syntax-highlights recognized lines,
2052 - reformats some of them for easier comprehension,
2054 - filters out less useful messages, and
2056 - (in some cases) calculates additional information,
2057 like the compression ratio or how a filter affected
2060 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
2061 without getting confused by the resulting amount of output. For example for
2062 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
2063 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
2064 will hide the "filter foo caused 0 hits" message.
2068 [B<--accept-unknown-messages>] Don't print warnings in case of unknown messages,
2069 just don't highlight them.
2071 [B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
2072 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
2073 This option is only intended to make embedding log excerpts in web pages easier.
2074 It does not escape any input!
2076 [B<--no-msecs>] Don't expect milisecond resolution
2078 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
2079 the filtered output is piped into less in which case the ANSI control
2080 codes don't work, or if the terminal itself doesn't support the control
2083 [B<--show-ineffective-filters>] Don't suppress log lines for filters
2084 that didn't modify the content.
2086 [B<--version>] Print version and exit.
2090 To monitor a log file:
2092 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
2094 Replace '-F' with '-f' if your tail implementation lacks '-F' support
2095 or if the log won't get rotated anyway. The log file location depends
2096 on your system (Doh!).
2098 To monitor Privoxy without having it write to a log file:
2100 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
2102 Again, the config file location depends on your system. Output redirection
2103 depends on your shell, the above works with bourne shells.
2105 To read a processed Privoxy log file from top to bottom, letting the content
2106 scroll by slightly faster than you can read:
2108 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
2110 This is probably only useful to fill screens in the background of haxor movies.
2114 Syntax highlighting with ANSI escape sequences will look strange
2115 if your background color isn't black.
2117 Some messages aren't recognized yet and will not be fully highlighted.
2119 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
2120 using earlier Privoxy versions will probably result in an increased amount
2121 of unrecognized log lines.
2123 Privoxy's log files tend to be rather large. If you use HTML
2124 highlighting some browsers can't handle them, get confused and
2125 will eventually crash because of segmentation faults or unexpected
2126 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
2131 Many settings can't be controlled through command line options yet.
