ULS Viewer crashes when viewing SharePoint 2013 logs

Hello there,

A quick tip for those who encountered the ULS viewer crash with SharePoint 2013 as my colleagues and me.

Scenario

  • SharePoint 2013
  • ULS viewer

Issue

When opening a SharePoint log containing “verbose” logging with ULS viewer, this one crashes after processing all the data. This makes the tool unusable at some extent.
This issue doesn’t appear if you don’t set the logging level to at least “Verbose“.

Fix

Although I don’t know what is going on in the background, the quick fix for this is to disable in the option the feature “correlation tree”.

  1. Open Uls Viewer
  2. Go in menu “Tools/Options…”
  3. Uncheck the option “Enable correlation tree”
    ULSViewer-crashes

 

 

 

 

 

 

 

 

Happy troubleshooting !

PowerPivot thumbnails requires Windows Server 2012 GUI

Hello,

We found out a small issue with PowerPivot 2012 and SharePoint 2013 this week.

You may be aware that the PowerPivot for SharePoint is able to create snapshots/thumbnail previews of your document which is then used to display a nice little image in the carrousel view.
This fancy little feature is generated under the hood by an executable located in the bin folder of the SharePoint installation folder (C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\15\bin).

While it works well under common context, it will fail in a particular scenario. I won’t give you all the different ways to troubleshoot this as Internet already as a ton of article around it but here’s one that is very useful :
http://blogs.technet.com/b/excel_services__powerpivot_for_sharepoint_support_blog/archive/2012/12/06/invoking-and-analyzing-the-getsnapshot-exe.aspx

Our scenario is as follow :

  • The server hosting SharePoint and Powerpivot is running Windows 2012
  • Windows Server 2012 is configured using MSI (Minimal Server Interface)

In this particular case, the “GallerySnapshot.exe” will crashes when processing the document.

 

 

 

 

If you look in the “info” file generated, you quickly find out that there is nothing relevant to help you. Here’s the content of the log file :
“<SnapshotCaptureLog serverUrl=”http://<webapp name>” workbookUrl=”http://<site url>/SharePoint/PpowerPivot/Book1.xlsx” fileNameBase=”thumbnail” snapshotCount=”26″ timeout=”600″ />”. That’s it ! Nothing else.

In the “GallerySnapshot.exe has stopped working” error window details, we can see a small hint of what’s going on : “Problem Signature 04: System.Windows.Forms”.

I performed the same exercise on a different server with the same result. I then intalled the windows feature Server Graphical Shell (Install-WindowsFeature Server-Gui-Shell) and restarted the server.

Once rebooted, running the GallerySnapshot.exe again with the same arguments went successfully.

To sum-up, if you require the file preview in a PowerPivot Gallery, you will necessarily have to configure your servers with at least the Graphical User Interface. Let’s hope Microsoft will remove this pre-requisite in a future cumulative update or service pack but until then, forget Windows Server 2012 MSI !

Sad, sad, sad.
