The main idea of having the Administration dashboard in BizTalk360 is to provide easy access to different sections in BizTalk360 "in a single click". To achieve this, we picked up the key functionalities of BizTalk360 that "we thought" customers would be using more often on a day-to-day basis. When the dashboard loads up in BizTalk360, it is not completely empty. We have pre-filled the dashboard with certain "Default Widgets" that will give you some valid insights into the environment.
You can add your own Dashboard(s) for different purposes - say, for example, you can create a dashboard that will have all the Monitoring widgets so that you can easily look at the health of your environment. Similarly, you can set up another dashboard for your users where they can easily keep track of the suspended service instances within the environment. We have also built the dashboard framework in a way that you can create your own Custom Widget.
