Real Time Telemetry for your Azure Function App using Application Insights

By | May 19, 2017

Application Insights helps us to track applications health in real time. You can track your application availability, performance issues, user’s session and diagnose crashes faster than ever. It provides a real-time dashboard for your app to monitor your application. It is fast, very easy to configure and provide very powerful insights for your application. We can capture the real-time telemetry using Application Insights for our Azure Function App as well. There are several ways to do that integration.

Integrate Application Insights While Creating your Azure Function App

 Navigate and Login to your Azure Portal, From New ->  Compute ->  Select Function App, or Search Function App in the Search the marketplace box. Then Create the Function App, by providing all required details including App Name, Subscription Details, Hosting Plan etc. 

To enable the Application Insight, set the last option  “Application Insights“ to ON.

With that, along with creating your Azure Function App, you will have an Application Insight created with mapped with current Azure Function.

 Using existing Application Insights for Azure Function App

If you have Application Insight already created and you want to integrate it with your Azure Function App, you can do that easily post your Azure Function is created.

Once you Azure Function is created, and you don’ t have configuration done, you will find Configured Features is empty under Overview Tab.

    Thanks for the Feedback. Appreciate it. Regarding your query, I think you can view the Application Insights details inside Visual Studio, irrespective of the services your using it. Which means, While debugging your Azure Function, if you connect the respective App Insights resources , in Visual Studio, you should be able to see the logs as long as your are sending back the telemetry. Are you facing some challenges ? Let me know.

    Thanks.
