Has anyone been able to put an ETA for inbound vehicles on a dashboard?

[ThomasRickett]

We are an ambulance company and we have a dashboard that tracks vehicles using AVL data. Our feed gives  current location and destination location, and shows the ambulance tracking on the map. But we aren't even sure if getting an updating ETA (Estimated Time of Arrival) is possible. I've searched on Network Analyst and while I can do this on a static point to point, but continuous updating doesn't appear to be offered. I was just wondering if anyone had solved this issue before.

To get an updated ETA, you can solve a two point OD to get the travel time left to reach the destination. You can also send a request to our logistic service to get that. Some more description of that is here:

Thank you Jay, I've been doing a lot of research on this. I am relatively new to Dashboards and Network Analyst. From what I've gathered I will need to construct an API direct request to the network service which I have enabled in our GIS Enterprise ArcGIS Portal. But how does the request return a feature that I can put in a dashboard. Any help would be appreciated.
