SQL Server Reporting Services (SSRS) Logging
This is another post that is for my own reference though likely useful to a number of people is on on the topic of SSRS logging. For the most part all the information you will need is at the following link;

For issues with SSRS in native mode enabling HTTP logging is very useful and creates log files in the same format as IIS, mostly because SSRS2005 is hosted in IIS and SSRS2008 onwards hosts ASP.Net itself so under the hood it is likely the same logging code as IIS iteself. This has proven very useful for myself so thought I'd share with my readers, whoever you are. :)
