 ## Metrics in ASP.NET Core gRPC
 
-The .NET Core runtime provides a set of components for emitting and observing metrics. These include APIs such as the <xref:System.Diagnostics.Tracing.EventSource> and <xref:System.Diagnostics.Tracing.EventCounter> classes. These APIs can emit basic numeric data that can be consumed by external processes, like the [dotnet-counters global tool](../../core/diagnostics/dotnet-counters.md), or Event Tracing for Windows. For more information about using `EventCounter` in your own code, see [EventCounter introduction](https://github.com/dotnet/runtime/blob/master/src/libraries/System.Diagnostics.Tracing/documentation/EventCounterTutorial.md).

 For more advanced metrics and for writing metric data to a wider range of data stores, you might try an open-source project called [App Metrics](https://www.app-metrics.io). This suite of libraries provides an extensive set of types to instrument your code. It also offers packages to write metrics to different kinds of targets that include time-series databases, such as Prometheus and InfluxDB, and [Application Insights](/azure/azure-monitor/app/app-insights-overview). The [App.Metrics.AspNetCore.Mvc](https://www.nuget.org/packages/App.Metrics.AspNetCore.Mvc/) NuGet package even adds a comprehensive set of basic metrics that are automatically generated via integration with the ASP.NET Core framework. The project website provides [templates](https://www.app-metrics.io/samples/grafana/) for displaying those metrics with the [Grafana](https://grafana.com/) visualization platform.

 ### Distributed tracing with `DiagnosticSource`
 
-.NET has an internal module that maps well to distributed traces and spans: [DiagnosticSource](https://github.com/dotnet/runtime/blob/master/src/libraries/System.Diagnostics.DiagnosticSource/src/DiagnosticSourceUsersGuide.md#diagnosticsource-users-guide). As well as providing a simple way to produce and consume diagnostics within a process, the `DiagnosticSource` module has the concept of an *activity*. An activity is effectively an implementation of a distributed trace, or a span within a trace. The internals of the module take care of parent/child activities, including allocating identifiers. For more information about using the `Activity` type, see the [Activity User Guide on GitHub](https://github.com/dotnet/runtime/blob/master/src/libraries/System.Diagnostics.DiagnosticSource/src/ActivityUserGuide.md#activity-user-guide).

 Because `DiagnosticSource` is a part of the core framework and later, it's supported by several core components. These include <xref:System.Net.Http.HttpClient>, Entity Framework Core, and ASP.NET Core, including explicit support in the gRPC framework. When ASP.NET Core receives a request, it checks for a pair of HTTP headers matching the [W3C Trace Context](https://www.w3.org/TR/trace-context) standard. If the headers are found, an activity is started by using the identity values and context from the headers. If no headers are found, an activity is started with generated identity values that match the standard format. Any diagnostics generated by the framework or by application code during the lifetime of this activity can be tagged with the trace and span identifiers. The `HttpClient` support extends this functionality further by checking for a current activity on every request, and automatically adding the trace headers to the outgoing request.
