AppDynamics serverless monitoring for Azure Functions gives you visibility into the performance of your applications that run as functions on Microsoft Azure. The .NET Agent supports Azure Functions hosted on App Service plans. Once installed, the .NET Agent automatically discovers business transactions in your Azure Functions.

You can monitor your applications running in Azure Functions exactly as you would any other application instrumented with the .NET Agent. Correlate business transactions between and through Azure Functions receive snapshots, create callgraphs, and integrate functions with End User Monitoring.
