In order to set up Export, you will need to use an Azure subscription. Exporting the data has an associated cost that will depend on the Azure service you are exporting to.

App Center Analytics allows you to continuously export all your Analytics raw data into Azure, specifically into Blob Storage and Application Insights. By exporting the data, you benefit from:

  • Unlimited retention by keeping your data as long as you need to and access to it when needed
  • Get answers by querying your raw data
  • Customize your own analytics dashboards
  • New feature set within Application Insights such as filtering and funnels

The data will be continously exported since the moment export is configured. The data for the two days previous to the export being configured will also be exported.

App Center offers two ways to export your data: standard export and custom export. Standard export will allow you to export the data with a one-click experience, using the azure subscription linked to the app. Custom export will provide you with more flexibility and the configurations will be customized in Azure.

Azure Subscription Linking


This step is only needed for Standard Export. For Custom Export, you don't need to attached the azure subscription to App Center.

Exporting an app's data to Azure, using our standard export, requires an Azure subscription linked to the app. Adding an azure subscription and linking it to an app needs to be done by the app owner (if the app doesn't belong to an organization) or by the organization admin.

Adding an Azure Subscription

  • App belonging to an organization: If you are the organization admin, go to the "Manage" section under the organization where the app belongs to.
  • App belonging to an user: If you are the app owner, go to user settings.
  • Under Azure, click "Add subscription". Then, you will need to add your Azure credentials and it will let you choose your preferred option from all the Azure subscriptions you have access to.

Linking an app to an Azure Subscription

Once you have added an Azure Subscription into your user/organization settings, you need to provide apps with access so that the subscription can be used within that app. By doing this, you are allowing any manager/developer in that app to use the subscription for exporting purposes. Note that this will have an associated cost that will be charge into your Azure Subscription.

Set up Export

  1. Go to the App Settings.
  2. Click on Export and select the New Export option.
  3. Choose your preferred destination (Blob Storage or Application Insights).
  4. Select the type of configuration you want (standard vs custom).

Standard Export

This provides a one-click experience. When selecting this option, all the resources will be created for you in Azure and the Azure Subscription attached to that app will be used. As mentioned above, this requires to have an Azure Subscription linked to your app.

Custom Export

This option allows you to customize your export configurations in Azure.

For Blob Storage:

  • Create a new resource of type Storage account of type blob.
  • Copy the connection string and add it into your App Center custom configurations. You will find the connection string in the Azure portal under Access Keys in the Settings tab.

Add the connection string in App Center

For Application Insights:

  • Create a new resource of type Application Insights.
  • Select the Application Type to be app center app type.
  • Copy the instrumentation key from the Azure portal and add it into your App Center custom configurations. You will find the instrumentation key in the Overview page in the Application Insights resource.

Add the instrumentation key in App Center

Azure Blob Storage

Azure Blob storage is a service for storing large amounts of unstructured object data, such as text or binary data, that can be accessed from anywhere in the world via HTTP or HTTPS. You can use Blob storage to expose data publicly to the world, or to store application data privately. Exporting the data to Blob Storage is a good choice for the case where you want to have an extended retention but not necessarily plan to access to the data very often. The data will be exported every minute and a new subfolder will be created. The data will be stored the year/month/day/hour/minute format (for example, https://<blob-storage-account>.blob.core.windows.net/archive/2017/12/09/04/03/logs.v1.data). The data will take up to 5 minutes to be shown in Azure Blob Storage.

The contents of the blob file is a JSON array of client device logs, that looks like this:

Azure Application Insights

Application Insights is an application performance management (APM) service that offers querying, segmentation, filtering, and usage analytics capabilities over your App Center event data. By adding the App Center SDK to your app and exporting the data into an App Center app-type Application Insights resource, you will get access to the following features:

  • Application Insights Analytics. Use a powerful query language to analyze your raw event data and create visualizations. You can export the results of your queries into PowerBI or Excel.
  • Users, Sessions and Events. Learn how many people are using each page and feature of your app, then segment by country, browser, or other properties to understand why.
  • Funnels and User flows. Understand how users navigate through your app. Identify bottlenecks. Discover ways to increase conversion rates and eliminate pain points.
  • Retention. Discover how many users return to use your app. Find out where and why they drop out.
  • Workbooks. Create interactive workbooks that combine usage analysis visualizations, Application Insights Analytics queries, and text to share insights on your team.

The App Center fields are mapped into Application Insights format. Here is the equivalence between the mapped fields:

Application Insights App Center
timestamp Time of the event
name Name of the custom event or type of data
customDimensions This includes several fields shown in the table below
session_Id Uniquely session identifier
user_Id Uniquely user identifier
application_Version Version of the application
client_Type, client_Model Device Model
client_OS OS type and version
sdkVersion App Center SDK version

The table below shows the field mapping for the "customDimensions" field.

Application Insights App Center
MessageType Type of event (session, event, ...)
AppId App Center App ID
CarrierCountry Carrier Country
TimeZoneOffset Time Zone Offset
CarrierName Carrier Type
Properties Properties attached to a custom event
ScreenSize Device's screen size
OsApiLevel API Level
Locale Device language

A sample AI query to retrieve custom events:

 | where name == "YourEventName"
 | extend Properties = todynamic(tostring(customDimensions.Properties))
 | extend YourPropertyName = Properties.YourPropertyName
