2080 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
2084 B<privoxy-log-parser> [B<--accept-unknown-messages>] [B<--html-output>]
2085 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--show-ineffective-filters>]
2090 B<privoxy-log-parser> reads Privoxy log messages and
2092 - syntax-highlights recognized lines,
2094 - reformats some of them for easier comprehension,
2096 - filters out less useful messages, and
2098 - (in some cases) calculates additional information,
2099 like the compression ratio or how a filter affected
2102 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
2103 without getting confused by the resulting amount of output. For example for
2104 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
2105 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
2106 will hide the "filter foo caused 0 hits" message.
2110 [B<--accept-unknown-messages>] Don't print warnings in case of unknown messages,
2111 just don't highlight them.
2113 [B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
2114 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
2115 This option is only intended to make embedding log excerpts in web pages easier.
2116 It does not escape any input!
2118 [B<--no-msecs>] Don't expect milisecond resolution
2120 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
2121 the filtered output is piped into less in which case the ANSI control
2122 codes don't work, or if the terminal itself doesn't support the control
2125 [B<--show-ineffective-filters>] Don't suppress log lines for filters
2126 that didn't modify the content.
2128 [B<--version>] Print version and exit.
2132 To monitor a log file:
2134 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
2136 Replace '-F' with '-f' if your tail implementation lacks '-F' support
2137 or if the log won't get rotated anyway. The log file location depends
2138 on your system (Doh!).
2140 To monitor Privoxy without having it write to a log file:
2142 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
2144 Again, the config file location depends on your system. Output redirection
2145 depends on your shell, the above works with bourne shells.
2147 To read a processed Privoxy log file from top to bottom, letting the content
2148 scroll by slightly faster than you can read:
2150 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
2152 This is probably only useful to fill screens in the background of haxor movies.
2156 Syntax highlighting with ANSI escape sequences will look strange
2157 if your background color isn't black.
2159 Some messages aren't recognized yet and will not be fully highlighted.
2161 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
2162 using earlier Privoxy versions will probably result in an increased amount
2163 of unrecognized log lines.
2165 Privoxy's log files tend to be rather large. If you use HTML
2166 highlighting some browsers can't handle them, get confused and
2167 will eventually crash because of segmentation faults or unexpected
2168 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
2173 Many settings can't be controlled through command line options yet.
