The "Statistics" item of your site's "Features" menu now includes a chart of approximate hits over the last two weeks. Click for more information.
This chart will give you a rough idea of the number of hits to your site over the past two weeks. Since crawling the full access log is very CPU-intensive (and is only included with our full statistics upgrade), we're using the basic site log (which doesn't include all hits) as a benchmark for the measurement, and multiplying it by a factor that roughly indicates the true number of hits. It's a real-time chart, so it will show up-to-the-minute results.
