通过性能监视，Sentry 可以跟踪您的软件性能，测量吞吐量和延迟等指标，并显示多个系统之间的错误影响。

安装

安装跟踪软件包：

ESM

# Using yarn
yarn add @sentry/tracing

# Using npm
npm install @sentry/tracing

CDN

<script
  <!--
    Note that `bundle.tracing.min.js` contains both `@sentry/browser` AND
    `@sentry/tracing`, and should therefore be used in place of
    `@sentry/browser`'s bundle rather than in addition to it.
  -->
  src="https://browser.sentry-cdn.com/5.29.2/bundle.tracing.min.js"
  integrity="sha384-4zxA5Bnxor/VkZae20EqPP3A/6vDlw1ZhqF7EvpmeTfWYFjPIDdaUSOk/q7G/bYw"
  crossorigin="anonymous"
></script>

配置

通过以下两种方式在您的应用中启用性能监控：

使用 SDK 配置中的 tracesSampleRate 选项将所有 transactions 的统一采样率设置为 0 到 1 之间的数字。(例如，要发送 20％ 的 transactions，请将 tracesSampleRate 设置为 0.2。)
通过为 tracesSampler 配置选项提供功能，基于 transaction 本身及其捕获的上下文动态控制采样率。

ESM

// If you're using one of our integration packages, like `@sentry/react` or
// `@sentry/angular`, substitute its name for `@sentry/browser` here
import * as Sentry from "@sentry/browser";

// If taking advantage of automatic instrumentation (highly recommended)
import { Integrations as TracingIntegrations } from "@sentry/tracing";
// Or, if only manually tracing
// import * as _ from "@sentry/tracing"
// Note: You MUST import the package in some way for tracing to work

Sentry.init({
  dsn: "https://examplePublicKey@o0.ingest.sentry.io/0",

  // This enables automatic instrumentation (highly recommended), but is not
  // necessary for purely manual usage
  integrations: [new TracingIntegrations.BrowserTracing()],

  // To set a uniform sample rate
  tracesSampleRate: 0.2

  // Alternatively, to control sampling dynamically
  tracesSampler: samplingContext => { ... }
});

如果设置了这些选项之一，则将在您的应用程序中启用跟踪。虽然这些选项是互斥的，但是如果您同时设置了这两个选项，tracesSampler 将具有优先权。您可以在 Sampling Transactions 中了解有关它们如何工作的更多信息。
