Overview:
SharePoint 2010 has a greatly improved development story. Part of that story is the addition of the Developer Dashboard. When activated a dashboard is added to the bottom each page that surfaces important debugging and performance tuning information.
For example, the developer dashboard will show how long a page took to load and all database (stored procedure) calls associated with the page processing.
To Enable the SharePoint 2010 Developer Dashboard:
Execute the following stsadm command from the command prompt.
stsadm -o setproperty -pn developer-dashboard -pv ondemand
Note: Remember to run the command prompt as administrator :)
Options:
On – The developer dashboard is created every time a page is rendered. It is displayed at the bottom of the page follow all page content.
Off – The developer developer dashboard is not added to pages.
OnDemand – An icon is added to the top right corner of the menu bar that toggles the displaying of the Developer Dashboard
“Top Right Corner of Menu Bar”
“Click the SharePoint 2010 Developer Dashboard Icon” to show or hide the dashboard at the bottom of the page.
Note: The developer dashboard is currently available as part of SharePoint 2010 Foundation and SharePoint 2010 Server.
