Reporting Services log files and sources

A report server and report server environment use various log destinations to record information about server operations and status. There are two basic categories of logging, execution logging, and trace logging. Execution logging includes information about report execution statistics, auditing, performance diagnosis and optimization. Trace logging is information about error messages and general diagnostics.

Log Description
Report server ExecutionLog and the ExecutionLog3 view The execution log is a SQL Server view stored in the report server database.

The report server execution log contains data about specific reports. The data includes when a report was run, who ran it, where it was delivered, and which rendering format was used.
SharePoint trace log For report servers running in SharePoint, the SharePoint trace logs contain Reporting Services information. You can also configure SSRS specific information for the SharePoint Unified Logging service. For more information, see Turn on Reporting Services events for the SharePoint trace log (ULS)
