14 # - LOG_LEVEL_CGI, LOG_LEVEL_ERROR, LOG_LEVEL_WRITE content highlighting
15 # - create fancy statistics
16 # - grep through Privoxy sources to find unsupported log messages
17 # - hunt down substitutions that match content from variables which
18 # can contain stuff like ()?'[]
19 # - replace $h{'foo'} with h('foo') where possible
20 # - hunt down XXX comments instead of just creating them
21 # - add example log lines for every regex and mark them up for
23 # - Handle incomplete input without Perl warning about undefined variables.
24 # - Use generic highlighting function that takes a regex and the
26 # - Add --compress and --decompress options.

2357 B<privoxy-log-parser> - A parser and syntax-highlighter for Privoxy log messages
2361 B<privoxy-log-parser> [B<--accept-unknown-messages>] [B<--html-output>]
2362 [B<--no-msecs>] [B<--no-syntax-higlighting>] [B<--statistics>]
2363 [B<--shorten-thread-ids>] [B<--show-ineffective-filters>]
2364 [B<--url-statistics-threshold>] [B<--version>]
2368 B<privoxy-log-parser> reads Privoxy log messages and
2370 - syntax-highlights recognized lines,
2372 - reformats some of them for easier comprehension,
2374 - filters out less useful messages, and
2376 - (in some cases) calculates additional information,
2377 like the compression ratio or how a filter affected
2380 With B<privoxy-log-parser> you should be able to increase Privoxy's log level
2381 without getting confused by the resulting amount of output. For example for
2382 "debug 64" B<privoxy-log-parser> will (by default) only show messages that
2383 affect the content. If a filter doesn't cause any hits, B<privoxy-log-parser>
2384 will hide the "filter foo caused 0 hits" message.
2388 [B<--accept-unknown-messages>] Don't print warnings in case of unknown messages,
2389 just don't highlight them.
2391 [B<--html-output>] Use HTML and CSS for the syntax highlighting. If this option is
2392 omitted, ANSI escape sequences are used unless B<--no-syntax-highlighting> is active.
2393 This option is only intended to make embedding log excerpts in web pages easier.
2394 It does not escape any input!
2396 [B<--no-msecs>] Don't expect milisecond resolution
2398 [B<--no-syntax-highlighting>] Disable syntax-highlighting. Useful when
2399 the filtered output is piped into less in which case the ANSI control
2400 codes don't work, or if the terminal itself doesn't support the control
2403 [B<--shorten-thread-ids>] Shorten the thread ids to a three-digit decimal number.
2404 Note that the mapping from thread ids to shortened ids is created at run-time
2405 and thus varies with the input.
2407 [B<--show-ineffective-filters>] Don't suppress log lines for filters
2408 that didn't modify the content.
2410 [B<--statistics>] Gather various statistics instead of syntax highlighting
2411 log messages. This is an experimental feature, if the results look wrong
2412 they very well might be. Also note that the results are pretty much guaranteed
2413 to be incorrect if Privoxy and Privoxy-Log-Parser aren't in sync.
2415 [B<--url-statistics-threshold>] Only show the request count for a ressource
2416 if it's above or equal to the given threshold. If the threshold is 0, URL
2417 statistics are disabled.
2419 [B<--version>] Print version and exit.
2423 To monitor a log file:
2425 tail -F /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log | B<privoxy-log-parser>
2427 Replace '-F' with '-f' if your tail implementation lacks '-F' support
2428 or if the log won't get rotated anyway. The log file location depends
2429 on your system (Doh!).
2431 To monitor Privoxy without having it write to a log file:
2433 privoxy --no-daemon /usr/jails/privoxy-jail/usr/local/etc/privoxy/config 2>&1 | B<privoxy-log-parser>
2435 Again, the config file location depends on your system. Output redirection
2436 depends on your shell, the above works with bourne shells.
2438 To read a processed Privoxy log file from top to bottom, letting the content
2439 scroll by slightly faster than you can read:
2441 B<privoxy-log-parser> < /usr/jails/privoxy-jail/var/log/privoxy/privoxy.log
2443 This is probably only useful to fill screens in the background of haxor movies.
2447 Syntax highlighting with ANSI escape sequences will look strange
2448 if your background color isn't black.
2450 Some messages aren't recognized yet and will not be fully highlighted.
2452 B<privoxy-log-parser> is developed with Privoxy 3.0.7 or later in mind,
2453 using earlier Privoxy versions will probably result in an increased amount
2454 of unrecognized log lines.
2456 Privoxy's log files tend to be rather large. If you use HTML
2457 highlighting some browsers can't handle them, get confused and
2458 will eventually crash because of segmentation faults or unexpected
2459 exceptions. This is a problem in the browser and not B<privoxy-log-parser>'s
2464 Many settings can't be controlled through command line options yet.
