I have a site collection in SharePoint 2010 Foundation that has several sub-sites within the one collection. I have setup all the correct settings in the Central Admin to turn on the logging to allow the 'Site Web Analytics reports' and these are being recorded and are working for every site except the top level site.
http://sharepoint/ --> Top Level Site --> Site Web Analytics reports do not work http://sharepoint/sub1 --> Sub Site 1 --> Site Web Analytics reports work correctly http://sharepoint/sub2 --> Sub Site 2 --> Site Web Analytics reports work correctly ... and so on...
The error I am getting on the top level site is
A web analytics report is not available for this site. Usage processing may be disabled on this server or the usage data for this site has not been processed yet.
but it should be being processed with the other data.
Is there something I am missing to get the top level site to start reporting the Web Analytics and therefore the site usage?
