1953 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
1957 B<privoxy-log-parser> [B<--accept-unknown-messages>] [B<--html-output>]
1958 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--show-ineffective-filters>]
1963 B<privoxy-log-parser> reads Privoxy log messages and
1965 - syntax-highlights recognized lines,
1967 - reformats some of them for easier comprehension,
1969 - filters out less useful messages, and
1971 - (in some cases) calculates additional information,
1972 like the compression ratio or how a filter affected
1975 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
1976 without getting confused by the resulting amount of output. For example for
1977 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
1978 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
1979 will hide the "filter foo caused 0 hits" message.
1983 [B<--accept-unknown-messages>] Don't print warnings in case of unknown messages,
1984 just don't highlight them.
1986 [B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
1987 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
1988 This option is only intended to make embedding log excerpts in web pages easier.
1989 It does not excape any input!
1991 [B<--no-msecs>] Don't expect milisecond resolution
1993 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
1994 the filtered output is piped into less in which case the ANSI control
1995 codes don't work, or if the terminal itself doesn't support the control
1998 [B<--show-ineffective-filters>] Don't suppress log lines for filters
1999 that didn't modify the content.
2001 [B<--version>] Print version and exit.
2005 To monitor a log file:
2007 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
2009 Replace '-F' with '-f' if your tail implementation lacks '-F' support
2010 or if the log won't get rotated anyway. The log file location depends
2011 on your system (Doh!).
2013 To monitor Privoxy without having it write to a log file:
2015 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
2017 Again, the config file location depends on your system. Output redirection
2018 depends on your shell, the above works with bourne shells.
2020 To read a processed Privoxy log file from top to bottom, letting the content
2021 scroll by slightly faster than you can read:
2023 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
2025 This is probably only useful to fill screens in the background of haxor movies.
2029 Syntax highlighting with ANSI escape sequences will look strange
2030 if your background color isn't black.
2032 Some messages aren't recognized yet and will not be fully highlighted.
2034 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
2035 using earlier Privoxy versions will probably result in an increased amount
2036 of unrecognized log lines.
2038 Privoxy's log files tend to be rather large. If you use HTML
2039 highlighting some browsers can't handle them, get confused and
2040 will eventually crash because of segmentation faults or unexpected
2041 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
2046 Many settings can't be controlled through command line options yet.
