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


privoxy-log-parser [--accept-unknown-messages] [--html-output] [--no-msecs] [--no-syntax-higlighting] [--show-ineffective-filters] [--version]


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.


[--accept-unknown-messages] Don't print warnings in case of unknown messages, just don't highlight them.

[--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 milisecond 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.

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

[--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.

[--version] Print version and exit.


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.


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.


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