訪問者は非常に高速な Web ログ アナライザーです。それまで 150,000、現代の PC 上のログの行/秒を処理できる、プレーン テキストまたは HTML、統計情報を出力、Google 特有のレポートの数と訪問者の一般的なパスの graphviz グラフを生成します。構成のあらゆる種類を必要としないもそれは処理する Web ログ ファイルの正確な形式と言われる必要があります。
--grep and --exclude options were added to process
only line matching or not matching specified
patterns. --ignore-404 was added in order to avoid
404 errors that are processed like other log lines
to create statistics. This is useful for sites
where there are a number of requests producing 404
error codes. A new report about users' screen
resolution and color depth was added, but it only
works after the inclusion of the JavaScript code
mentioned in the README file. Some other minor
fixes were made.
This release adds an important bugfix in the unique visitors algorithm.
The output is now nearer to reality (though unique visitors stats are
always a guess without the use of a cookie).
Two new reports were added: "AdSensed pages" which
shows pages accessed recently by the Google
AdSense bot, and "Human Languages" via Google's
referer "hl" GET parameter (this does not need to
resolve IP addresses to guess the language of
visitors). Keyword based referer spam filtering
was added. The browser list was updated with the
ability to detect different versions of IE and
Gecko-based browsers. A problem regarding long
lines in the HTML output causing issues sending
reports by email was fixed. The parsing code and
the unique visitors algorithm were improved.
This release added a fix required for googlebot changes, new reports including a new bidimensional map that shows traffic levels in the whole year, a display of unique visitors for every month, better generation of graphviz graphs including percentages in arcs, nodes for google, external links and no referer, and a reduction in memory usage. The highlight color for weekends was changed to be more visible. Most stats are now made by unique visits and not by the number of accesses. Many bugs were fixed and a real manual page was added.
As result of Google's bots User Agent string change, visitors were no longer able to produce two Google-related reports (Googled Pages and Browsers). This bug is fixed, and all users should upgrade in order to get reliable outputs.
