 ## Performance counters for applications running in Azure Web Apps
 
-Both ASP.NET and ASP.NET Core applications deployed to Azure Web Apps run in a special sandbox environment. This environment does not allow direct access to system performance counters. However, a limited subset of counters are exposed as environment variables as described [here](https://github.com/projectkudu/kudu/wiki/Perf-Counters-exposed-as-environment-variables). Application Insights SDK for ASP.NET and ASP.NET Core collects performance counters from Azure Web Apps from these special environment variables. Only a subset of counters are available in this environment, and the full list can be found [here.](https://github.com/microsoft/ApplicationInsights-dotnet-server/blob/develop/Src/PerformanceCollector/Perf.Shared/Implementation/WebAppPerformanceCollector/CounterFactory.cs)
