I've defined a data source in cep console, moved over to the cep analytics dashboard and tried to create a new gadget. This fails with an error. No datasources available. Looking at the source code for creating gadgets there is a dependency to an analytics service stub that's not part of the default install. I switched over to using DAS and got the same error. Anyone got any pointers to getting this to work?

Can you mentioned the DAS version and also paste the error log. Also can you make sure the datasource connection is successful by clicking the "Test connection" button?. I hope you have copied the relevant datasource driver jar to
/repository/components/lib folder. – Anuruddha Feb 28 '16 at 02:37

Actually data source of the gadget is not data sources for databases. Data source for the gadgets are data streams in CEP and DAS.
There are two types of gadgets.
1. Real time processing gadgets - These gadgets will plot data in real time as immediately data received for the stream. In order to create these, you need to create a UI publisher for the stream [1]. Then the stream will be displayed as a data source in dashboard gadget creation. Please refer CEP documentation on how to create a real time gadget [2].
2. Batch processing gadgets - These gadgets will load data from analytics event tables and plot. In WSO2 DAS if you create a stream and persist it to event table [3], those will streams will be shown as data sources in analytic dashboard. Please refer DAS documentation on how to create a gadget [4]
