I have released my Cube Status project (http://cubestatus.codeplex.com) to http://www.codeplex.com.
This web part for SharePoint provides the possibility to visualize both the current status of a SQL Server Analysis Services (SSAS) cube or tabular model (BISM) and some of its metadata.
This web part can be used in BI portal type pages in SharePoint to show the current status of a cube used for reports and analysis. This means that there is no need to guess the update status or last process time etc. of a cube.
Both the source code and a .wsp solution file for deployment are available for download from the project page: http://cubestatus.codeplex.com
This project is described in more detail here
This project also works quite well together with the SQL Server Agent Job Status project found at http://jobstatus.codeplex.com and with more details here
Please, feel free to suggest updates and new features etc. either here on the blog or on CodePlex.
