Hi, I need to know if it is possible to monitor or debug a published report on SharePoint 2010 during the rendering phase. I need to analyse this error message: "An error occurred during client rendering. Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index". Thanks

Hi Pscorca, In general, the information and procedures for monitoring report server activity and performance is the same regardless of whether the report server runs in native mode or SharePoint integrated mode. However, SharePoint products and technologies offer diagnostic logging events to help you monitor activity and performance for a SharePoint server. For example, Reporting Services servers in SharePoint integrated mode can write Reporting Services events to the SharePoint Unified Logging Service (ULS) starting with SQL Server 2008 R2. For more information, please see: How to: Turn on Reporting Services events for the SharePoint trace log (ULS)Configure diagnostic logging settings (Windows SharePoint Services) In this issue, the error can occur due to various possible causes such as report layout. At this time, I suggest that you refer to the following thread which has the same topic: http://social.msdn.microsoft.com/Forums/en-US/sqlreportingservices/thread/2b921e79-a618-4cd7-8d71-84ef9c40ec6d Hope this helps.
