Paramasivam,
As the Build Dashboard source code is available on GitHub, you can modify it to display the Fields that are available in Agile Central. Here is the Source Code:
app-catalog/BuildDashboardApp.html at master · RallyApps/app-catalog · GitHub
Here is information about adding a Custom HTML page in Agile Central:
Custom HTML | CA Agile Central Help
The only fields available on the Build Object in Agile Central, according to the Web Services Documentation, https://rally1.rallydev.com/slm/doc/webservice/ , that may be useful are:
CreationDate
Subscription
Workspace
BuildDefinition
Changesets
Duration
Message
Number
Start
Status
Uri
Some of these are collections, so would take some other querying to get the info.
Hope that helps.
Michael
