This graph shows the access stats for the site for as long as the site keeps statistics...
The numbers represent the page hits served from the CMS used (Drupal). Not included:
- Static hits : files like CSS pages or static images
- RSS feed hits, about 12% of the total dynamic hits during 2009Q2
- Login and registration pages, which are massive spamming targets and therefore not very representative
The graph is generated dynamically using GD2.
If you want to see the most popular pages behind these statistics...
The Drupal implications of generating such a graph are described here.
But you'd rather do a PHP-GTK UI, wouldn't you ? For this, you can use the site XML-RPC API function access_stats. So go ahead, and submit your PHP-GTK graphing function using these stats !
