Hi Stephen, to add to what Robert posted...
first hint I'd give you, to have everything ready (sites, edge groups, trunks etc..) before setting up the edge, that makes this process much smoother.
When it comes to alerts - there are none that I'd be aware of in Cloud Admin.
You basically can see the status of the device and some stats regarding the device (screenshot attached).
You can also see some metrics for your devices (calls per trunk, ram or cpu utilization, calls per edge...).
I've seen some monitoring solution based on AWS Lambda - you could try that one:
Front end: https://bitbucket.org/eccemea/edge-monitoring-interface/src/master/
Back end: https://bitbucket.org/eccemea/purecloud-edge-monitor/src/master/
Here's a general webpage with description of platform API: https://developer.mypurecloud.com/api/rest/index.html
Good luck!
