PRIVOXY-LOG-PARSER(1)  User Contributed Perl Documentation PRIVOXY-LOG-PARSER(1)

NAME
     privoxy-log-parser - A parser and syntax-highlighter for Privoxy log mes-
     sages

SYNOPSIS
     privoxy-log-parser [--detect-inactivity] [--inactivity-threshold msecs]
     [--html-output] [--no-msecs] [--no-syntax-higlighting] [--statistics]
     [--shorten-thread-ids] [--show-ineffective-filters] [--url-statis-
     tics-threshold] [--version]

DESCRIPTION
     privoxy-log-parser reads Privoxy log messages and

     - syntax-highlights recognized lines,

     - reformats some of them for easier comprehension,

     - filters out less useful messages, and

     - (in some cases) calculates additional information,
       like the compression ratio or how a filter affected
       the content size.

     With privoxy-log-parser you should be able to increase Privoxy's log level
     without getting confused by the resulting amount of output. For example for
     "debug 64" privoxy-log-parser will (by default) only show messages that af-
     fect the content. If a filter doesn't cause any hits, privoxy-log-parser
     will hide the "filter foo caused 0 hits" message.

OPTIONS
     [--detect-inactivity] Instead of syntax highlighting, detect periods of log
     inactivity of more than the amount of milliseconds specified with the --in-
     activity-threshold option. Mainly useful for debugging.

     [--host-statistics-threshold] Only show the request count for a host if
     it's above or equal to the given threshold. If the threshold is 0, host
     statistics are disabled.

     [--html-output] Use HTML and CSS when syntax highlighting. If this option
     is omitted, ANSI escape sequences are used unless --no-syntax-highlighting
     is active.  This option is only intended to make embedding log excerpts in
     web pages easier.	It does not escape any input!

     [--inactivity-threshold msecs] Specifies the number of milliseconds between
     log messages to consider inactivity when running in [--detect-inactivity]
     mode.

     [--keep-date] Don't remove the date when printing highlighted log messages.
     Useful when parsing multiple log files at once.

     [--no-msecs] Don't expect millisecond resolution

     [--no-syntax-highlighting] Disable syntax-highlighting. Useful when the
     filtered output is piped into less in which case the ANSI control codes
     don't work, or if the terminal itself doesn't support the control codes.

     [--passed-request-statistics-threshold] Only show the request count for a
     passed requests if it's above or equal to the given threshold. If the
     threshold is 0, passed request statistics are disabled.

     [--shorten-thread-ids] Shorten the thread ids to a three-digit decimal num-
     ber.  Note that the mapping from thread ids to shortened ids is created at
     run-time and thus varies with the input.

     [--show-ineffective-filters] Don't suppress log lines for filters that
     didn't modify the content.

     [--show-complete-request-distribution] Show the complete client request
     distribution in the --statistics output. Without this option only the ten
     most common numbers are shown.

     [--statistics] Gather various statistics instead of syntax highlighting log
     messages. This is an experimental feature, if the results look wrong they
     very well might be. Also note that the results are pretty much guaranteed
     to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.

     [--strict-checks] When generating statistics, look more careful at the in-
     put data and abort if it is unexpected, even if it doesn't affect the re-
     sults. Significantly slows the parsing down and is not expected to catch
     any problems that matter.	When highlighting, print warnings in case of un-
     known messages which can't be properly highlighted.

     [--unbreak-lines-only] Tries to fix lines that got messed up by a broken or
     interestingly configured mail client and thus are no longer recognized
     properly.	Only fixes some breakage, but may be good enough or at least
     better than nothing.  Doesn't do anything else, so you probably want to
     pipe the output into privoxy-log-parser again.

     [--url-statistics-threshold] Only show the request count for a resource if
     it's above or equal to the given threshold. If the threshold is 0, URL sta-
     tistics are disabled.

     [--version] Print version and exit.

EXAMPLES
     To monitor a log file:

     tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log |
     privoxy-log-parser

     Replace '-F' with '-f' if your tail implementation lacks '-F' support or if
     the log won't get rotated anyway. The log file location depends on your
     system (Doh!).

     To monitor Privoxy without having it write to a log file:

     privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config
     2>&1 | privoxy-log-parser

     Again, the config file location depends on your system. Output redirection
     depends on your shell, the above works with bourne shells.

     To read a processed Privoxy log file from top to bottom, letting the con-
     tent scroll by slightly faster than you can read:

     privoxy-log-parser < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log

     This is probably only useful to fill screens in the background of haxor
     movies.

CAVEATS
     Syntax highlighting with ANSI escape sequences will look strange if your
     background color isn't black.

     Some messages aren't recognized yet and will not be fully highlighted.

     privoxy-log-parser is developed with Privoxy 3.0.7 or later in mind, using
     earlier Privoxy versions will probably result in an increased amount of un-
     recognized log lines.

     Privoxy's log files tend to be rather large. If you use HTML highlighting
     some browsers can't handle them, get confused and will eventually crash be-
     cause of segmentation faults or unexpected exceptions. This is a problem in
     the browser and not privoxy-log-parser's fault.

BUGS
     Many settings can't be controlled through command line options yet.
