privoxy-log-parser(1)

NAME

   privoxy-log-parser - A parser and syntax-highlighter for Privoxy log
   messages

SYNOPSIS

   privoxy-log-parser [--html-output] [--no-msecs]
   [--no-syntax-higlighting] [--statistics] [--shorten-thread-ids]
   [--show-ineffective-filters] [--url-statistics-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 affect the content. If a filter doesn't cause any hits,
   privoxy-log-parser will hide the "filter foo caused 0 hits" message.

OPTIONS

   [--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 for the 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!

   [--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.

   [--shorten-thread-ids] Shorten the thread ids to a three-digit decimal
   number.  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
   input data and abort if it is unexpected, even if it doesn't affect the
   results. Significantly slows the parsing down and is not expected to
   catch any problems that matter.  When highlighting, print warnings in
   case of unknown 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 statistics 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
   content 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 unrecognized 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 because 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.
