You don’t need to configure anything special on Azure.
The only issue is the “Real” performance metrics through the performance monitor won’t work on Azure because an Azure Website doesn’t run on its own Machine etc, it’s a shared environment. So turn that part off in the performance engine and add your own numbers there, like some random number generation or something else you can capture like logs or users registering or whatever your use case that changes dynamically is.
Locally since you’re running it on a full blown machine all the performance monitors work.
Azure has other performance monitors for websites that I belive you can tap into but I haven’t really played around with those so I can’t advise too much there.
This is meant to be a proof of concept on how one could push data from the server to the client leveraging .NET, SignalR, and angular and the performance metrics seemed like a great use case but unless you have a full server you won’t have access to the performance monitors.
