Application Insights 中的数据收集、保留和存储Data collection, retention, and storage in Application Insights

在应用中安装 Azure Application Insights SDK 后,它会将有关应用的遥测数据发送到云中。When you install Azure Application Insights SDK in your app, it sends telemetry about your app to the Cloud. 负责的开发人员自然想要确切了解发送了哪些数据、数据的后续情况,以及如何控制数据。Naturally, responsible developers want to know exactly what data is sent, what happens to the data, and how they can keep control of it. 具体而言,是否发送了敏感数据?数据存储在何处?其安全性怎样?In particular, could sensitive data be sent, where is it stored, and how secure is it?

首先,简短的答案是:First, the short answer:

  • “按原样”运行的标准遥测模块不太可能将敏感数据发送到服务。The standard telemetry modules that run "out of the box" are unlikely to send sensitive data to the service. 遥测考虑到负载、性能和使用指标、异常报告和其他诊断数据。The telemetry is concerned with load, performance and usage metrics, exception reports, and other diagnostic data. 诊断报告中显示的主要用户数据是 URL;但是,应用在任何情况下都不应该将敏感数据以明文形式放在 URL 中。The main user data visible in the diagnostic reports are URLs; but your app shouldn't in any case put sensitive data in plain text in a URL.
  • 可以编写发送其他自定义遥测数据的代码,帮助进行诊断与监视使用情况。You can write code that sends additional custom telemetry to help you with diagnostics and monitoring usage. (这种可扩展性是 Application Insights 的突出特性之一)。在编写此代码时,有可能不小心包含个人数据和其他敏感数据。(This extensibility is a great feature of Application Insights.) It would be possible, by mistake, to write this code so that it includes personal and other sensitive data. 如果应用程序使用此类数据,则应对编写的所有代码进行彻底评审。If your application works with such data, you should apply a thorough review process to all the code you write.
  • 开发和测试应用时,可以轻松检查 SDK 发送的内容。While developing and testing your app, it's easy to inspect what's being sent by the SDK. 数据会显示在 IDE 和浏览器的调试输出窗口中。The data appears in the debugging output windows of the IDE and browser.
  • 创建新的 Application Insights 资源时,可以选择存储位置。You can select the location when you create a new Application Insights resource. 此处详细了解每个区域的 Application Insights 可用性。Know more about Application Insights availability per region here.
  • 检查收集的数据,因为这可能包括在某些情况下允许但在其他情况下不允许的数据。Review the collected data, as this may include data that is allowed in some circumstances but not others. 设备名称就是一个很好的例子。A good example of this is Device Name. 服务器中的设备名称不会对隐私造成影响,而且很有用,但是电话或笔记本电脑中的设备名称可能会对隐私造成影响,而且用处不大。The device name from a server has no privacy impact and is useful, but a device name from a phone or laptop may have a privacy impact and be less useful. 主要针对目标服务器开发的 SDK 将在默认情况下收集设备名称,该名称可能需要在正常事件和异常中被被覆盖。An SDK developed primarily to target servers, would collect device name by default, and this may need to be overwritten in both normal events and exceptions.

本文的余下部分详细阐述上述答案。The rest of this article elaborates more fully on these answers. 本文的内容简单直白,因此,可以将其转达给不属于直属团队的同事。It's designed to be self-contained, so that you can show it to colleagues who aren't part of your immediate team.

什么是 Application Insights?What is Application Insights?

Azure Application Insights 是 Azure 提供的一项服务,可帮助改进实时应用程序的性能和可用性。Azure Application Insights is a service provided by Azure that helps you improve the performance and usability of your live application. 它在应用程序运行时全程进行监视,包括测试期间以及发布或部署之后。It monitors your application all the time it's running, both during testing and after you've published or deployed it. Application Insights 可创建图表和表格来显示多种信息,例如,一天中的哪些时间用户最多、应用的响应能力如何,以及应用依赖的任何外部服务是否顺利地为其提供服务。Application Insights creates charts and tables that show you, for example, what times of day you get most users, how responsive the app is, and how well it is served by any external services that it depends on. 如果出现崩溃、故障或性能问题,可以搜索详细的遥测数据来诊断原因。If there are crashes, failures or performance issues, you can search through the telemetry data in detail to diagnose the cause. 此外,如果应用的可用性和性能有任何变化,服务会向你发送电子邮件。And the service will send you emails if there are any changes in the availability and performance of your app.

要获取此功能,需在应用程序中安装 Application Insights SDK,该 SDK 将成为应用程序代码的一部分。In order to get this functionality, you install an Application Insights SDK in your application, which becomes part of its code. 当应用运行时,SDK 将监视其操作,并将遥测发送到 Application Insights 服务。When your app is running, the SDK monitors its operation and sends telemetry to the Application Insights service. 这是 Azure 中国托管的云服务。This is a cloud service hosted by Azure China. (不过,Application Insights 适用于任何应用程序,而不只是 Azure 中托管的应用程序。)(But Application Insights works for any applications, not just applications that are hosted in Azure.)

Application Insights 服务存储并分析遥测数据。The Application Insights service stores and analyzes the telemetry. 若要查看分析或搜索已存储的遥测数据,可以登录到 Azure 帐户并打开应用程序的 Application Insights 资源。To see the analysis or search through the stored telemetry, you sign in to your Azure account and open the Application Insights resource for your application. 还可以与团队的其他成员或指定的 Azure 订户共享数据访问权限。You can also share access to the data with other members of your team, or with specified Azure subscribers.

可以从 Application Insights 服务导出数据,例如,导出到数据库或外部工具。You can have data exported from the Application Insights service, for example to a database or to external tools. 需要为每项工具提供从服务获取的特殊密钥。You provide each tool with a special key that you obtain from the service. 如果需要,可以吊销该密钥。The key can be revoked if necessary.

Application Insights SDK 可用于多种应用程序类型:托管在自己的 Java EE 或 ASP.NET 服务器中或者 Azure 中的 Web 服务;Web 客户端(即网页中运行的代码);桌面应用和服务;设备应用,例如 Windows Phone、iOS 和 Android。Application Insights SDKs are available for a range of application types: web services hosted in your own Java EE or ASP.NET servers, or in Azure; web clients - that is, the code running in a web page; desktop apps and services; device apps such as Windows Phone, iOS, and Android. 它们都将遥测数据发送到相同的服务。They all send telemetry to the same service.

它收集哪些数据?What data does it collect?

有三种数据源:There are three sources of data:

  • SDK。可以在开发阶段或者在运行时将它与应用集成。The SDK, which you integrate with your app either in development or at run time. 不同类型的应用程序有不同的 SDK。There are different SDKs for different application types. 此外还有网页 SDK,连同页面一起加载到最终用户的浏览器中。There's also an SDK for web pages, which loads into the end user's browser along with the page.

    • 每个 SDK 有许多模块,这些模块使用不同的技术收集不同类型的遥测数据。Each SDK has a number of modules, which use different techniques to collect different types of telemetry.
    • 如果在开发环境中安装 SDK,则除了使用标准模块发送自己的遥测数据以外,还可以使用 SDK 的 API 发送这些数据。If you install the SDK in development, you can use its API to send your own telemetry, in addition to the standard modules. 这些自定义遥测数据可以包含所要发送的任何数据。This custom telemetry can include any data you want to send.
  • 在某些 Web 服务器中,还装有与应用一起运行并发送有关 CPU、内存和网络占用量的遥测数据的代理。In some web servers, there are also agents that run alongside the app and send telemetry about CPU, memory, and network occupancy. 例如,Azure VM、Docker 主机和 Java EE 服务器都可能拥有此类代理。For example, Azure VMs, Docker hosts, and Java EE servers can have such agents.

收集哪些类型的数据?What kinds of data are collected?

主要类别如下:The main categories are:

  • Web 服务器遥测数据 - HTTP 请求。Web server telemetry - HTTP requests. URI、处理请求花费的时间、响应代码、客户端 IP 地址。Uri, time taken to process the request, response code, client IP address. Session id.Session id.
  • 网页 - 页面、用户和会话计数。Web pages - Page, user and session counts. 页面加载时间。Page load times. 异常。Exceptions. Ajax 调用。Ajax calls.
  • 性能计数器 - 内存、CPU、IO、网络占用量。Performance counters - Memory, CPU, IO, Network occupancy.
  • 客户端和服务器上下文 - OS、区域性、设备类型、浏览器和屏幕分辨率。Client and server context - OS, locale, device type, browser, screen resolution.
  • 异常和崩溃 - 堆栈转储build id、CPU 类型。Exceptions and crashes - stack dumps, build id, CPU type.
  • 依赖项 - 对外部服务的调用,例如 REST、SQL、AJAX。Dependencies - calls to external services such as REST, SQL, AJAX. URI 或连接字符串、持续时间、成功结果、命令。URI or connection string, duration, success, command.
  • 跟踪日志自定义遥测 - 在日志或遥测中编写的任何内容Trace logs and custom telemetry - anything you code into your logs or telemetry.

更多详细信息More detail.

如何验证收集了哪些信息?How can I verify what's being collected?

如果使用 Visual Studio 开发应用,请在调试模式下运行应用 (F5)。If you're developing the app using Visual Studio, run the app in debug mode (F5). 遥测数据会显示在“输出”窗口中。The telemetry appears in the Output window. 在该窗口中,可以复制遥测数据并将其格式设置为 JSON 以便于检查。From there, you can copy it and format it as JSON for easy inspection.

屏幕截图,显示在 Visual Studio 中的调试模式下运行应用程序。

“诊断”窗口中还提供了一个可方便阅读的视图。There's also a more readable view in the Diagnostics window.

针对网页,请打开浏览器的调试窗口。For web pages, open your browser's debugging window.

按 F12 打开“网络”选项卡。

是否可以编写代码来筛选遥测数据,然后将它发送出去?Can I write code to filter the telemetry before it is sent?

可以编写遥测处理器插件来实现此目的。This would be possible by writing a telemetry processor plugin.

数据保留多长时间?How long is the data kept?

原始数据点(即,可以在 Analytics 中查询并在“搜索”中检查的项)最多可以保留 730 天。Raw data points (that is, items that you can query in Analytics and inspect in Search) are kept for up to 730 days. 可以选择保留期限 30 天、60 天、90 天、120 天、180 天、270 天、365 天、550 天或 730 天。You can select a retention duration of 30, 60, 90, 120, 180, 270, 365, 550 or 730 days. 如果需要将数据保留超过 730 天,则可以使用连续导出在数据引入过程中将其复制到存储帐户。If you need to keep data longer than 730 days, you can use Continuous Export to copy it to a storage account during data ingestion.

保留时间超过 90 天的数据将产生额外费用。Data kept longer than 90 days will incur addition charges. Azure Monitor 定价页上详细了解 Application Insights 定价。Learn more about Application Insights pricing on the Azure Monitor pricing page.

1 分钟粒度的聚合数据(即,在指标资源管理器中显示的计数、平均值和其他统计信息)可保留 90 天。Aggregated data (that is, counts, averages and other statistical data that you see in Metric Explorer) are retained at a grain of 1 minute for 90 days.

调试快照将存储 15 天。Debug snapshots are stored for 15 days. 此保留策略是逐个应用程序进行设置。This retention policy is set on a per-application basis. 如果需要,可以在 Azure 门户中打开支持案例,以请求增加此值。If you need to increase this value, you can request an increase by opening a support case in the Azure portal.

谁可以访问该数据?Who can access the data?

你和团队成员(如果使用组织帐户)可以看到数据。The data is visible to you and, if you have an organization account, your team members.

你和团队成员可以导出数据,还可以将其复制到其他位置并传递给其他人员。It can be exported by you and your team members and could be copied to other locations and passed on to other people.

Azure 如何处理应用发送到 Application Insights 的信息?What does Azure do with the information my app sends to Application Insights?

Azure 只使用这些数据来向你提供服务。Azure uses the data only in order to provide the service to you.

数据保存在哪个位置?Where is the data held?

  • 在中国。In China. 创建新的 Application Insights 资源时,可以选择存储位置。You can select the location when you create a new Application Insights resource.

这是否意味着必须在中国托管我的应用?Does that mean my app has to be hosted in China?

  • 否。No. 应用程序可在任何位置运行,不管是在自己的本地主机中还是云中。Your application can run anywhere, either in your own on-premises hosts or in the cloud.

数据的安全性如何?How secure is my data?

Application Insights 是一项 Azure 服务。Application Insights is an Azure Service. Azure Security, Privacy, and Compliance white paper(Azure 安全性、隐私性和遵从性白皮书)中介绍了安全政策。Security policies are described in the Azure Security, Privacy, and Compliance white paper.

数据存储在 Azure 服务器中。The data is stored in Azure servers. 对于 Azure 门户中的帐户,Azure 安全性、隐私和合规性文档中介绍了相关帐户限制。For accounts in the Azure portal, account restrictions are described in the Azure Security, Privacy, and Compliance document.

Azure 工作人员对数据的访问将受到限制。Access to your data by Azure personnel is restricted. 我们只有在获得许可以及为了帮助你使用 Application Insights 而有必要访问时才访问数据。We access your data only with your permission and if it is necessary to support your use of Application Insights.

跨所有客户应用程序(例如数据速率和平均跟踪大小)的聚合数据用于改善 Application Insights。Data in aggregate across all our customers' applications (such as data rates and average size of traces) is used to improve Application Insights.

其他人的遥测数据是否会干扰我的 Application Insights 数据?Could someone else's telemetry interfere with my Application Insights data?

他们可以使用检测密钥将附加的遥测数据发送到帐户,而检测密钥在网页的代码中。They could send additional telemetry to your account by using the instrumentation key, which can be found in the code of your web pages. 如果附加数据过多,指标会错误地呈现应用的性能和使用情况。With enough additional data, your metrics would not correctly represent your app's performance and usage.

如果与其他项目共享代码,请务必删除检测密钥。If you share code with other projects, remember to remove your instrumentation key.

数据是否已加密?Is the data encrypted?

在数据中心之间移动的所有数据都经过静态加密。All data is encrypted at rest and as it moves between data centers.

从应用程序传输到 Application Insights 服务器的数据是否经过加密?Is the data encrypted in transit from my application to Application Insights servers?

是。我们使用 https 将数据从几乎所有 SDK(包括 Web 服务器、设备和 HTTPS 网页)发送到门户。Yes, we use https to send data to the portal from nearly all SDKs, including web servers, devices, and HTTPS web pages.

SDK 是否创建临时本地存储?Does the SDK create temporary local storage?

是。如果无法访问终结点,一些遥测通道在本地暂留数据。Yes, certain Telemetry Channels will persist data locally if an endpoint cannot be reached. 请查看下面的内容,以确定哪些框架和遥测通道受影响。Please review below to see which frameworks and telemetry channels are affected.

利用本地存储的遥测通道会在 TEMP 或 APPDATA 目录中创建临时文件,但仅限于运行应用程序的特定帐户。Telemetry channels that utilize local storage create temp files in the TEMP or APPDATA directories, which are restricted to the specific account running your application. 当终结点暂时不可用或达到限制值时,可能会发生这种情况。This may happen when an endpoint was temporarily unavailable or you hit the throttling limit. 解决此问题后,遥测通道便会恢复发送所有新数据和暂留数据。Once this issue is resolved, the telemetry channel will resume sending all the new and persisted data.

此持久数据不会在本地加密。This persisted data is not encrypted locally. 如果这是一个问题,请检查数据并限制私人数据的收集。If this is a concern, review the data and restrict the collection of private data. (有关详细信息,请参阅如何导出和删除私人数据。)(For more information, see How to export and delete private data.)

如果客户需要根据特定安全要求配置此目录,可以针对每个框架进行配置。If a customer needs to configure this directory with specific security requirements, it can be configured per framework. 请确保运行应用程序的进程对此目录拥有写入权限,并确保此目录受保护,以免遥测数据遭用户意外读取。Please make sure that the process running your application has write access to this directory, but also make sure this directory is protected to avoid telemetry being read by unintended users.


C:\Users\username\AppData\Local\Temp 用于暂留数据。C:\Users\username\AppData\Local\Temp is used for persisting data. 此位置无法通过配置目录进行配置,只有拥有所需凭据的特定用户,才有权访问此文件夹。This location isn't configurable from the config directory and the permissions to access this folder are restricted to the specific user with required credentials. (有关详细信息,请参阅实现。)(For more information, see implementation.)


默认情况下,ServerTelemetryChannel 使用当前用户的本地应用数据文件夹 %localAppData%\Microsoft\ApplicationInsights 或临时文件夹 %TMP%By default ServerTelemetryChannel uses the current user’s local app data folder %localAppData%\Microsoft\ApplicationInsights or temp folder %TMP%. (请参阅此处的实现。)(See implementation here.)

通过配置文件:Via configuration file:

<TelemetryChannel Type="Microsoft.ApplicationInsights.WindowsServer.TelemetryChannel.ServerTelemetryChannel,   Microsoft.AI.ServerTelemetryChannel">

通过代码:Via code:

  • 从配置文件中删除 ServerTelemetryChannelRemove ServerTelemetryChannel from configuration file
  • 将此代码片段添加到配置中:Add this snippet to your configuration:
    ServerTelemetryChannel channel = new ServerTelemetryChannel();
    channel.StorageFolder = @"D:\NewTestFolder";
    TelemetryConfiguration.Active.TelemetryChannel = channel;


默认情况下,ServerTelemetryChannel 使用当前用户的本地应用数据文件夹 %localAppData%\Microsoft\ApplicationInsights 或临时文件夹 %TMP%By default ServerTelemetryChannel uses the current user’s local app data folder %localAppData%\Microsoft\ApplicationInsights or temp folder %TMP%. (请参阅此处的实现。)(See implementation here.)

在 Linux 环境中,除非指定了存储文件夹,否则将禁用本地存储。In a Linux environment, local storage will be disabled unless a storage folder is specified.


随着 2.15.0-beta3 版的推出,现可为 Linux、Mac 和 Windows 自动创建更大的本地存储。With the release 2.15.0-beta3 and greater local storage is now automatically created for Linux, Mac, and Windows. 对于非 Windows 系统,SDK 将根据以下逻辑自动创建本地存储文件夹:For non Windows systems the SDK will automatically create a local storage folder based on the following logic:

  • ${TMPDIR} - 如果设置了 ${TMPDIR} 环境变量,则使用此位置。${TMPDIR} - if ${TMPDIR} environment variable is set this location is used.
  • /var/tmp - 如果前一个位置不存在,请尝试 /var/tmp/var/tmp - if the previous location does not exist we try /var/tmp.
  • /tmp - 如果前两个位置都不存在,请尝试 tmp/tmp - if both the previous locations do not exist we try tmp.
  • 如果这些位置都不存在,则不会创建本地存储,且仍然需要手动配置。If none of those locations exist local storage is not created and manual configuration is still required. 了解有关实现的完整详细信息For full implementation details.

下面的代码片段展示了如何在 Startup.cs 类的 ConfigureServices() 方法中设置 ServerTelemetryChannel.StorageFolderThe following code snippet shows how to set ServerTelemetryChannel.StorageFolder in the ConfigureServices() method of your Startup.cs class:

services.AddSingleton(typeof(ITelemetryChannel), new ServerTelemetryChannel () {StorageFolder = "/tmp/myfolder"});

(有关详细信息,请参阅 AspNetCore 自定义配置。)(For more information, see AspNetCore Custom Configuration.)


默认情况下,%TEMP%/appInsights-node{INSTRUMENTATION KEY} 用于暂留数据。By default %TEMP%/appInsights-node{INSTRUMENTATION KEY} is used for persisting data. 只有当前用户和管理员,才有权访问此文件夹。Permissions to access this folder are restricted to the current user and Administrators. (请参阅此处的实现。)(See implementation here.)

可更改 Sender.ts 中的静态变量 Sender.TEMPDIR_PREFIX 的运行时值,以替代文件夹前缀 appInsights-nodeThe folder prefix appInsights-node can be overridden by changing the runtime value of the static variable Sender.TEMPDIR_PREFIX found in Sender.ts.

JavaScript(浏览器)JavaScript (browser)

HTML5 会话存储用于保存数据。HTML5 Session Storage is used to persist data. 使用两个单独的缓冲区:AI_bufferAI_sent_bufferTwo separate buffers are used: AI_buffer and AI_sent_buffer. 经过批处理并等待发送的遥测存储在 AI_buffer 中。Telemetry that is batched and waiting to be sent is stored in AI_buffer. 刚刚发送的遥测将存放在 AI_sent_buffer 中,直到引入服务器做出响应表明已成功接收。Telemetry that was just sent is placed in AI_sent_buffer until the ingestion server responds that it was successfully received. 成功接收遥测后,将从所有缓冲区中删除这些遥测。When telemetry is successfully received, it's removed from all buffers. 发生暂时性故障(例如,用户失去网络连接)时,遥测将保留在 AI_buffer 中,直到成功接收或引入服务器做出响应表明遥测无效(例如,架构错误或太旧)。On transient failures (for example, a user loses network connectivity), telemetry remains in AI_buffer until it is successfully received or the ingestion server responds that the telemetry is invalid (bad schema or too old, for example).

可以通过将 enableSessionStorageBuffer 设置为 false 来禁用遥测缓冲区。Telemetry buffers can be disabled by setting enableSessionStorageBuffer to false. 关闭会话存储时,本地数组将被改用为持久存储。When session storage is turned off, a local array is instead used as persistent storage. 由于 JavaScript SDK 在客户端设备上运行,因此用户可以通过浏览器的开发人员工具来访问此存储位置。Because the JavaScript SDK runs on a client device, the user has access to this storage location via their browser's developer tools.

OpenCensus PythonOpenCensus Python

默认情况下,OpenCensus Python SDK 使用当前用户文件夹 %username%/.opencensus/.azure/By default OpenCensus Python SDK uses the current user folder %username%/.opencensus/.azure/. 只有当前用户和管理员,才有权访问此文件夹。Permissions to access this folder are restricted to the current user and Administrators. (请参阅此处的实现。)包含持久数据的文件夹将根据生成遥测的 Python 文件命名。(See implementation here.) The folder with your persisted data will be named after the Python file that generated the telemetry.

可以通过在所用导出程序的构造函数中传入 storage_path 参数来更改存储文件的位置。You may change the location of your storage file by passing in the storage_path parameter in the constructor of the exporter you are using.


如何使用 TLS 1.2 将数据发送到 Application Insights?How do I send data to Application Insights using TLS 1.2?

为了确保传输到 Application Insights 终结点的数据的安全性,我们强烈建议客户将其应用程序配置为至少使用传输层安全性 (TLS) 1.2。To insure the security of data in transit to the Application Insights endpoints, we strongly encourage customers to configure their application to use at least Transport Layer Security (TLS) 1.2. 我们发现旧版 TLS/安全套接字层 (SSL) 容易受到攻击,尽管出于向后兼容,这些协议仍可正常工作,但我们 不建议使用,并且行业即将放弃对这些旧协议的支持。Older versions of TLS/Secure Sockets Layer (SSL) have been found to be vulnerable and while they still currently work to allow backwards compatibility, they are not recommended, and the industry is quickly moving to abandon support for these older protocols.

PCI 安全标准委员会规定 2018 年 6 月 30 日是停用旧版 TLS/SSL 并升级到更安全协议的截止时间。The PCI Security Standards Council has set a deadline of June 30, 2018 to disable older versions of TLS/SSL and upgrade to more secure protocols. 在 Azure 放弃旧版支持后,如果应用程序/客户端无法通过最低版本 TLS 1.2 进行通信,则你无法将数据发送到 Application Insights。Once Azure drops legacy support, if your application/clients cannot communicate over at least TLS 1.2 you would not be able to send data to Application Insights. 测试和验证应用程序对 TLS 的支持的方法根据操作系统/平台以及应用程序使用的语言/框架而异。The approach you take to test and validate your application's TLS support will vary depending on the operating system/platform as well as the language/framework your application uses.

除非必要,否则我们不建议将应用程序显式设置为仅使用 TLS 1.2,因为这可能会破坏平台级安全功能,导致无法自动检测并利用推出的更新且更安全的协议,例如 TLS 1.3。We do not recommend explicitly setting your application to only use TLS 1.2 unless necessary as this can break platform level security features that allow you to automatically detect and take advantage of newer more secure protocols as they become available such as TLS 1.3. 我们建议针对应用程序代码执行全面的审核,以检查特定 TLS/SSL 版本的硬编码。We recommend performing a thorough audit of your application's code to check for hardcoding of specific TLS/SSL versions.
