Will enabling application insights interrupt my azure function?

Question

I have a Node.js functions app running in azure and it is processing thousands of requests every minute, I would like to enable Application Insights using the Azure Portal in order to diagnose an issue but I fear this may interrupt the function while it configures itself.

Is this a valid concern?

All the documentation I have found regarding Application Insights does not mention the impact on any running applications.

Answer 1

Adding AI integration is only a matter of adding a key to app settings, but any edits to app settings require a function app to restart, so yes it will affect your function.
