-After completing this task, you understand how to have your application participate in tracing with [Jaeger](https://www.jaegertracing.io/),
-regardless of the language, framework, or platform you use to build your application.
+完成此任务后，您将了解如何让您的应用程序参与 [Jaeger](https://www.jaegertracing.io/)的追踪，
+而不管您用来构建应用程序的语言、框架或平台是什么。
 
-This task uses the [Bookinfo](/docs/examples/bookinfo/) sample as the example application.
+此任务使用 [Bookinfo](/zh/docs/examples/bookinfo/) 作为演示的应用程序。
 
-To learn how Istio handles tracing, visit this task's [overview](../overview/).
+要了解 Istio 如何处理追踪，请查看这个任务的[概述](../overview/)。
 
-## Before you begin
+## 开始之前{#before-you-begin}
 
-1.  To set up Istio, follow the instructions in the [Installation guide](/docs/setup/install/istioctl)
-    and then configure:
+1. 要设置 Istio，按照[安装指南](/zh/docs/setup/install/operator)中的说明进行操作。
 
-    a) a demo/test environment by setting the `--set values.tracing.enabled=true` install option to enable tracing "out of the box"
+    a) 通过设置 `--set values.tracing.enabled = true` 安装选项以启用 tracing 的“开箱即用”的演示/测试环境
 
-    b) a production environment by referencing an existing Jaeger instance, e.g. created with the [operator](https://github.com/jaegertracing/jaeger-operator), and then setting the `--set values.global.tracer.zipkin.address=<jaeger-collector-service>.<jaeger-collector-namespace>:9411` install option.
+    b) 通过使用现有 Jaeger 实例（例如使用 [operator](https://github.com/jaegertracing/jaeger-operator)进行创建，然后设置`--set values.global.tracer.zipkin.address = <jaeger-collector-service>.<jaeger -collector-namespace>:9411` 的安装选项。
 
     {{< warning >}}
-    When you enable tracing, you can set the sampling rate that Istio uses for tracing.
-    Use the `values.pilot.traceSampling` option to set the sampling rate. The default sampling rate is 1%.
+    启用跟踪时，可以设置 Istio 用于跟踪的采样率。
+    使用这个 `values.pilot.traceSampling` 选项设置采样率。默认的采样率为 1%.
     {{< /warning >}}
 
-1.  Deploy the [Bookinfo](/docs/examples/bookinfo/#deploying-the-application) sample application.
+1. 部署 [Bookinfo](/zh/docs/examples/bookinfo/#deploying-the-application) 示例应用程序。
 
-## Accessing the dashboard
+## 访问仪表盘{#accessing-the-dashboard}
 
-[Remotely Accessing Telemetry Addons](/docs/tasks/observability/gateways) details how to configure access to the Istio addons through a gateway. Alternatively, to use a Kubernetes ingress, specify the option `--set values.tracing.ingress.enabled=true` during install.
+[远程访问遥测插件](/zh/docs/tasks/observability/gateways)详细介绍了如何通过网关配置对 Istio 插件的访问。或者，如果要使用 Kubernetes ingress，请在安装过程中指定选项 `--set values.tracing.ingress.enabled = true`。
 
-For testing (and temporary access), you may also use port-forwarding. Use the following, assuming you've deployed Jaeger to the `istio-system` namespace:
+对于测试（或临时访问），您也可以使用端口转发。假设已将 Jaeger 部署到 “istio-system” 命名空间，请使用以下内容：
 
 {{< text bash >}}
 $ kubectl -n istio-system port-forward $(kubectl -n istio-system get pod -l app=jaeger -o jsonpath='{.items[0].metadata.name}') 15032:16686
 {{< /text >}}
 
-Open your browser to [http://localhost:15032](http://localhost:15032).
+打开您的浏览器并访问 [http://localhost:15032](http://localhost:15032)。
 
-## Generating traces using the Bookinfo sample
+## 使用 Bookinfo 示例产生追踪{#generating-traces-using-the-Bookinfo-sample}
 
-1.  When the Bookinfo application is up and running, access `http://$GATEWAY_URL/productpage` one or more times
-    to generate trace information.
+1. 当 Bookinfo 应用程序启动并运行时，访问 `http://$GATEWAY_URL/productpage` 一次或多次以生成追踪信息。
 
-    {{< boilerplate trace-generation >}}
+1. 从仪表盘左边面板的 **Service** 下拉列表中选择 `productpage` 并点击 **Find Traces**：
 
-1.  From the left-hand pane of the dashboard, select `productpage.default` from the **Service** drop-down list and click
-    **Find Traces**:
+    {{< image link="./istio-tracing-list.png" caption="追踪仪表盘" >}}
 
-    {{< image link="./istio-tracing-list.png" caption="Tracing Dashboard" >}}
+1. 点击位于最上面的最近一次追踪，查看对应最近一次访问 `/productpage` 的详细信息：
 
-1.  Click on the most recent trace at the top to see the details corresponding to the
-    latest request to the `/productpage`:
+    {{< image link="./istio-tracing-details.png" caption="详细追踪视图" >}}
 
-    {{< image link="./istio-tracing-details.png" caption="Detailed Trace View" >}}
+1. 追踪信息由一组 span 组成，每个 span 对应一个 Bookinfo service。这些 service 在执行 `/productpage` 请求时被调用，或是 Istio 内部组件，例如：`istio-ingressgateway`
 
-1.  The trace is comprised of a set of spans,
-    where each span corresponds to a Bookinfo service, invoked during the execution of a `/productpage` request, or
-    internal Istio component, for example: `istio-ingressgateway`.
+## 清理{#cleanup}
 
-## Cleanup

-1.  Remove any `kubectl port-forward` processes that may still be running:
+1. 停止任何可能还在运行的 `kubectl port-forward` 进程：
 
     {{< text bash >}}
     $ killall kubectl
     {{< /text >}}
 
-1.  If you are not planning to explore any follow-on tasks, refer to the
-    [Bookinfo cleanup](/docs/examples/bookinfo/#cleanup) instructions
-    to shutdown the application.
+1. 如果您没有计划探索任何接下来的任务，请参考 [Bookinfo 清理](/docs/examples/bookinfo/#cleanup)中的说明，关闭整个应用程序。
