Please note: The contents of this post are based on the SharePoint Server 2010 Beta 1
The Central Administration site for SharePoint 2010 has a new section: Monitoring. Inside Monitoring, the application provides a Health Status section.
Clicking on 'Review problems and solutions' will display any issues that reside in your SharePoint farm.
Be careful on this page! Especially when clicking on individual items. The 'Fix automatically' button really just updates the list right now which makes it appear that the item is actually fixed.
Recently I had the following error appear in my list:Title Data corruptions are detected in content databases.
This issue was mysteriously fixed within two seconds when clicking 'Fix automatically'. (I wasn't buying it)
I was told that this functionality is still being working on heavily and should be cleared up in the next version of sp2010.
