Is it supported at all?
We tested out internally remote Analytics agent with the.Net Core micro agent. This functionality works same as it would work with any Full Fledged .Net Agent .
If you have Analytics Agent installed on a remote host or you are running Analytics Agent on a non default port then you can use the "appdynamics.analytics.agent.url" environment variable and point it to correct endpoint.
