You can't base decisions on assumptions. What you can't measure you can't manage. Familiar? Of course, and what you want to do with your software is specifically what's hinted: measure how people use it. Azure Application Insights is a tool for this, being an application telemetry service. Now we created an Orchard module for it for easy integration!
You can also chek out an overview of AI and a demonstration of the module on the Orchard Community Meeting's recording.
Azure Application Insights is a very useful tool when operating Orchard applications and allows you to response to any issues quickly. Check out the module!
