We are currently working towards a solution on this. I will be sure to follow-up on this thread when it is implemented.

I wanted to let you know that a new feature has been released in which data source monitoring has been made easier.
If there's a data source error or errors, a red icon will display in the side nav beside Data Sources. If you click the icon you will go to the Data Source list page, where you can find red icons beside the the offending data source (may be more than one). Click the error icon to go to that particular data source details page. If there is red text there you can click it to see the error and attempt resolve it.
Please let me know if you have any feedback!
