SQL Server 2012 ULS logging for the Reporting Services integration with SharePoint

  • Artículo

 

Most of you know that in 2008 R2 RS in SharePoint mode started logging reporting services events into SharePoint ULS trace logs.

 

ULS(Unified Logging Service) trace log files are stored on every SharePoint server individually and provide a running audit trail showing details (including detailed error information) of events that occur on that server. You can find more information on ULS logs here

 

In SQL Server 2012 ULS logging for the Reporting Services integration with SharePoint feature fills in the gaps not filled by existing logging capability via Report Server logs, IIS logs, and ULS logs via WSS categories such as “General”, “Web part”,etc..

 

This comprises:

  • SOAP Proxy code called by RS report viewer web part and web pages,
  • New HTTP Redirector code,
  • New Local mode processing and rendering, and
  • Web pages with:
    • Commonly used code eg. Central Admin RS configuration pages,
    • Exceptions raised that may or may not be displayed in the UI.

 

I was looking at the MSDN documentation for the various ULS categories and looks like its missing some details (https://msdn.microsoft.com/en-us/library/ff487871).

 

I am going to talk about some of the new categories added as part of the 2012 release.

 

RS feature registers with SharePoint under the Product area named “SQL Server Reporting Services”with several categories corresponding to each bucket mentioned earlier:

 

These are some of the new categories added as part of SQL Server 2012 release.

Tools for viewing ULS logs:

 

You could in theory open ULS logs on notepad, however you wouldn’t make use of the the rich formatting of these log files.

 

I almost always use one of ULS log viewer applications available on the web. Some of my favorites are:

 

https://archive.msdn.microsoft.com/ULSViewer (This is what I use all the time)

  • I love the live monitoring feature (play, pause and stop) and also the correlation tree feature.
  • Though the tool is quite easy to use the page also has a link to detailed documentation) 

 

https://sharepointlogviewer.codeplex.com/ (seems to be well supported)

  • I like the popup and email notifications feature.
  • It can also run in system tray. All this without just a standalone exe
