運作原理
新增 Performance Monitoring SDK 後，Firebase 會自動開始收集
在應用程式中使用幾種常見程序的資料，例如：
Performance Monitoring 會使用追蹤記錄收集這些程序的相關資料。追蹤記錄為
此報表包含應用程式中兩點之間擷取的資料。
針對每筆追蹤記錄收集的效能資料稱為指標，會有所不同
視追蹤記錄類型而定舉例來說，當應用程式發生問題時
網路要求時，追蹤記錄會收集網路要求的重要指標
監控要求監控作業，例如回應時間和酬載大小
每當應用程式的執行個體執行受監控的程序時，相關追蹤記錄就會
系統也會自動收集該應用程式執行個體的屬性資料。適用對象

Performance Monitoring helps you\nto understand in real time where the performance of your app can be improved so\nthat you can use that information to fix performance issues.\n\n\u003cbr /\u003e\n\nReady to get started? Choose your platform:\n\n[iOS+](/docs/perf-mon/get-started-ios)\n[Android](/docs/perf-mon/get-started-android)\n[Web](/docs/perf-mon/get-started-web)\n[Flutter](/docs/perf-mon/flutter/get-started)\n\nKey capabilities\n\n|-------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| Automatically measure app startup time, HTTP network requests, and more | When you integrate the Performance Monitoring SDK into your app, you don't need to write any code before your app starts automatically monitoring several critical aspects of performance. For native apps, the SDK logs startup time, rendering data by screen, and activity while in the foreground or background. For web apps, the SDK logs aspects like first contentful paint, ability for users to interact with your app, and more. |\n| Gain insight into situations where app performance could be improved | Optimizing the performance of your app can be challenging when you don't know exactly why it is falling short of user expectations. That's why Performance Monitoring lets you see performance metrics broken down by [*attributes*](/docs/perf-mon/attributes), like country, device, app version, and OS level. |\n| Customize monitoring for your app | You can instrument [*custom code traces*](/docs/perf-mon/custom-code-traces) to capture your app's performance in specific situations, like when you load a new screen or display a new interactive feature. And, you can create *custom metrics* on these custom code traces to count events that you define (like cache hits) during those traces. |\n| Identify significant changes in app performance | Identifying and resolving major app performance issues, like network outages, is vital to the success of your app. Performance Monitoring lets you [set up and customize alerts](/docs/perf-mon/alerts) for the most critical parts of your app so you can see and respond to performance pitfalls -- before they affect your users. |\n\nHow does it work?\n\nWhen you add the Performance Monitoring SDK, Firebase *automatically* starts collecting\ndata for several common processes in your app, for example:\n\n|---|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------|\n| | - [App start up time for Apple and Android apps](/docs/perf-mon/app-start-foreground-background-traces) - [Screen rendering for Apple and Android apps](/docs/perf-mon/screen-traces) | - [Page loading for web apps](/docs/perf-mon/page-load-traces) - [Network requests for all types of apps](/docs/perf-mon/network-traces) |\n\nPerformance Monitoring uses ***traces*** to collect data about these processes. A trace is\na report that contains data captured between two points in time in your app.\n\nThe collected performance data for each trace are called ***metrics*** and vary\ndepending on the type of trace. For example, when an instance of your app issues\na network request, the trace collects metrics that are important for network\nrequest monitoring, like response time and payload size.\n\nEach time an instance of your app runs a monitored process, the associated trace\nalso automatically collects ***attributes*** data for that app instance. For\nexample, if an Android app issues a network request, the trace collects the\ndevice, app version, and other attributes for that specific app instance. You\ncan use these attributes to filter your performance data and learn if specific\nuser segments are experiencing issues.\n\nThe out-of-the-box traces from Performance Monitoring get you started with monitoring your\napp, but to learn about the performance of specific tasks or flows, try out\n[instrumenting your own custom traces of code](/docs/perf-mon/custom-code-traces)\nin your app.\n\nImplementation path\n\n|---|---------------------------------------------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|\n| | Add the Performance Monitoring SDK to your app | You can add the Performance Monitoring SDK to your app, along with any other Firebase products that you want to use in your app. [Apple platforms](/docs/perf-mon/get-started-ios) \\| [Android](/docs/perf-mon/get-started-android) \\| [Web](/docs/perf-mon/get-started-web) \\| [Flutter](/docs/perf-mon/flutter/get-started) |\n| | *(Optional)* Instrument custom code traces and custom metrics in your app | Using the Performance Monitoring SDK, you can instrument [custom code traces and custom metrics](/docs/perf-mon/custom-code-traces) to measure specific aspects of your app's performance. |\n| | Monitor performance data in the console in real time | In the [Firebase console](//console.firebase.google.com/project/_/performance), you can monitor performance data from your users to learn the specific situations where your app's performance could be improved. You can also break down the performance data by [attributes](/docs/perf-mon/attributes), like app version, country, device, or OS. |\n\nUser data\n\nPerformance Monitoring does not permanently store any personally identifiable\ninformation (such as names, email addresses, or phone numbers). While monitoring\nHTTP network requests, Performance Monitoring uses URLs (not including URL parameters)\nto build aggregated and anonymous URL patterns that are eventually persisted\nand shown in the Firebase console.\n\nFor more details, refer to the\n[Examples of information collected by\nPerformance Monitoring](/support/privacy#performance-monitoring-collected-info).\n\nNext steps\n\n- To get started using Performance Monitoring in your app, visit:\n\n - [Get Started with Performance Monitoring for Apple platforms](/docs/perf-mon/get-started-ios)\n - [Get Started with Performance Monitoring for Android](/docs/perf-mon/get-started-android)\n - [Get Started with Performance Monitoring for web](/docs/perf-mon/get-started-web)\n - [Get Started with Performance Monitoring on Flutter](/docs/perf-mon/flutter/get-started)\n- To learn about setting up alerts, see [Set up alerts for performance issues](https://firebase.google.com/docs/perf-mon/alerts)."]]
