+# OpenTelemetry 
+
+https://opentelemetry.io/
+
+OpenTelemetry is a collection of tools, APIs, and SDKs. Use it to instrument, generate, collect, and export telemetry data (metrics, logs, and traces) to help you analyze your software’s performance and behavior.
+
+## Integration
+
+You can find it [here](https://opentelemetry.io/docs/instrumentation/net/getting-started/) about how to use OpenTelemetry in console applications or ASP.NET Core, at here we mainly describe how to tracing CAP data to OpenTelemetry.
+
+### Configuration
+
+Install the CAP OpenTelemetry package into the project.
+
+```C#
+dotnet add package DotNetCore.Cap.OpenTelemetry
+```
+
+The OpenTelemetry data comes from [diagnostics](diagnostics.md), add the configuration to enable data collection.
+
+```C#
+services.AddCap(x =>
+{
+    //***
+    x.UseOpenTelemetry();  // <-- Add this line
+});
+
+```
+
+Add the instrumentation of CAP to the configuration of OpenTelemetry.
+
+```C#
+services.AddOpenTelemetryTracing((builder) => builder
+    .AddAspNetCoreInstrumentation()
+    .AddCapInstrumentation()    // <-- Add this line
+    .AddZipkinExporter()
+);
+```
+
+Here is a diagram of CAP's tracking data in Zipkin:

+
+OpenTelemetry是工具、api和sdk的集合。 使用它来检测、生成、收集和导出遥测数据(度量、日志和跟踪)，以帮助您分析软件的性能和行为。
+
+## 集成
+
+You can find it [here](https://opentelemetry.io/docs/instrumentation/net/getting-started/) about how to use OpenTelemetry in console applications or ASP.NET Core, at here we mainly describe how to tracing CAP data to OpenTelemetry.
+
+你可以在[这里](https://opentelemetry.io/docs/instrumentation/net/getting-started/)找到关于如何在控制台应用或ASP.NET Core 中使用OpenTelemetry。
+在这里我们主要描述如何将CAP集成到OpenTelemetry中。
+
+### 配置
+
+安装CAP的OpenTelemetry包到项目中。
+
+```C#
+dotnet add package DotNetCore.Cap.OpenTelemetry
+```
+
+OpenTelemetry 的跟踪数据来自于[Diagnostics](diagnostics.md)发送的诊断数据，使用下面的配置行来启用收集数据。
+
+```C#
+services.AddCap(x =>
+{
+    //***
+    x.UseOpenTelemetry();  // <-- Add this line
+});
+
+```
+
+添加 CAP Instrumentation 到 OpenTelemetry的扩展配置中。
+
+```C#
+services.AddOpenTelemetryTracing((builder) => builder
+    .AddAspNetCoreInstrumentation()
+    .AddCapInstrumentation()    // <-- Add this line
+    .AddZipkinExporter()
+);
+```
+
+以下是CAP的跟踪数据在 Zipkin 中的一个示意图：
