Hi, The usage report can't be generated after i changed the log file location to "D:\sharepoint Log\UAP" from Central Administration > Operations > Usage Analysis Processing since i found that the default location is lack of storage. I already add WSS_ADMIN_WPG and WSS_WPG to above folder with full control permission. Checked that SP can generate the subfolder like "D:\sharepoint Log\UAP\2EBB1E4F-86B6-4E82-BC87-B13F7BFF6EE1\2010-08-19" however they have not contain any log file. Can anyone tell me how to solve it? Thanks. Best regards, Edward

Hi, The Diagnostic Logging have consumed most of the space. You need also change the location of the Diagnostic Logging. Please go to OperationsàLogging and ReportingàDiagnostic Logging to set the location.
