PowerBI
PRODIn this section, we provide guides and references to use the PowerBI connector.
Configure and schedule PowerBI metadata and profiler workflows from the OpenMetadata UI:
Requirements
To access the PowerBI APIs and import dashboards, charts, and datasets from PowerBI into OpenMetadata, a PowerBI Pro
license is necessary.
PowerBI dataflows are not yet supported.
OpenMetadata does not support Power BI usage ingestion because the Power BI Usage API does not support Service Principal authentication.
When configuring Azure Authentication, ensure that "Allow public client flows" is enabled. This setting is required to support authentication for public client applications.
PowerBI Admin and Non-Admin APIs:
While configuring the PowerBI ingestion you can choose whether to use the PowerBI Admin APIs to retrieve the metadata or use the PowerBI Non-Admin APIs. Please check below for the the difference in their functionality:
- Enabled (Use PowerBI Admin APIs) Using the admin APIs will fetch the dashboard and chart metadata from all the workspaces available in the PowerBI instance.
When using the PowerBI Admin APIs, the table and dataset information used to generate lineage is gathered using the PowerBI Scan Result API. This API has no limitations and hence does not restrict getting the necessary data for generating lineage.
- Disabled (Use Non-Admin PowerBI APIs) Using the non-admin APIs will only fetch the dashboard and chart metadata from the workspaces that have the security group of the service principal assigned to them.
When using the PowerBI Non-Admin APIs, the table and dataset information used to generate lineage is gathered using the PowerBI Get Dataset Tables API. This API only retrieves the table information if the dataset is a Push Dataset. Hence the lineage can only be created for push datasets in this case.
For more information please visit the PowerBI official documentation here.
PowerBI Account Setup
Follow the steps below to configure the account setup for PowerBI connector:
Step 1: Enable API permissions from the PowerBI Admin console
We extract the information from PowerBI using APIs, this is a manual step a PowerBI Admin needs to do to ensure we can get the right information.
Login to the Power BI as Admin and from Tenant
settings allow below permissions.
- Allow service principles to use Power BI APIs
- Allow service principals to use read-only Power BI admin APIs
- Enhance admin APIs responses with detailed metadata
Step 2: Create the App in Azure AD
Please follow the steps mentioned here for setting up the Azure AD application service principle.
Step 3: Provide necessary API permissions to the Azure AD app
Go to the Azure Ad app registrations
page, select your app and add the dashboard permissions to the app for PowerBI service and grant admin consent for the same:
The required permissions are:
Dashboard.Read.All
Optional Permissions: (Without granting these permissions, the dataset information cannot be retrieved and the datamodel and lineage processing will be skipped)
Dataset.Read.All
Make sure that in the API permissions section Tenant related permissions are not being given to the app Please refer here for detailed explanation
Step 4: PowerBI Workspaces
The service principal does not take into account the default user workspaces e.g My Workspace
.
Create new workspaces in PowerBI by following the document here
For reference here is a thread referring to the same
Python Requirements
To run the PowerBI ingestion, you will need to install:
Metadata Ingestion
All connectors are defined as JSON Schemas. Here you can find the structure to create a connection to PowerBI.
In order to create and run a Metadata Ingestion workflow, we will follow the steps to create a YAML configuration able to connect to the source, process the Entities if needed, and reach the OpenMetadata server.
The workflow is modeled around the following JSON Schema
1. Define the YAML Config
This is a sample config for PowerBI:
Source Configuration - Service Connection
clientId: PowerBI Client ID.
To get the client ID (also know as application ID), follow these steps:
- Log into Microsoft Azure.
- Search for App registrations and select the App registrations link.
- Select the Azure AD app you're using for embedding your Power BI content.
- From the Overview section, copy the Application (client) ID.
clientSecret: PowerBI Client Secret.
To get the client secret, follow these steps:
- Log into Microsoft Azure.
- Search for App registrations and select the App registrations link.
- Select the Azure AD app you're using for embedding your Power BI content.
- Under Manage, select Certificates & secrets.
- Under Client secrets, select New client secret.
- In the Add a client secret pop-up window, provide a description for your application secret, select when the application secret expires, and select Add.
- From the Client secrets section, copy the string in the Value column of the newly created application secret.
tenantId: PowerBI Tenant ID.
To get the tenant ID, follow these steps:
- Log into Microsoft Azure.
- Search for App registrations and select the App registrations link.
- Select the Azure AD app you're using for Power BI.
- From the Overview section, copy the Directory (tenant) ID.
scope: Service scope.
To let OM use the Power BI APIs using your Azure AD app, you'll need to add the following scopes:
- https://analysis.windows.net/powerbi/api/.default
Instructions for adding these scopes to your app can be found by following this link: https://analysis.windows.net/powerbi/api/.default.
authorityUri: Authority URI for the service.
To identify a token authority, you can provide a URL that points to the authority in question.
If you don't specify a URL for the token authority, we'll use the default value of https://login.microsoftonline.com/.
hostPort: URL to the PowerBI instance.
To connect with your Power BI instance, you'll need to provide the host URL. If you're using an on-premise installation of Power BI, this will be the domain name associated with your instance.
If you don't specify a host URL, we'll use the default value of https://app.powerbi.com to connect with your Power BI instance.
Pagination Entity Per Page:
The pagination limit for Power BI APIs can be set using this parameter. The limit determines the number of records to be displayed per page.
By default, the pagination limit is set to 100 records, which is also the maximum value allowed.
Use Admin APIs:
Option for using the PowerBI admin APIs:
Refer to the section here to get more information.
- Enabled (Use PowerBI Admin APIs)
- Disabled (Use Non-Admin PowerBI APIs)
pbitFilesSource: Source to get the .pbit files to extract lineage information. Select one of local, azureConfig, gcsConfig, s3Config.
pbitFileConfigType
: Determines the storage backend type (azure, gcs, or s3).securityConfig
: Authentication credentials for accessing the storage backend.prefixConfig
: Details of the location in the storage backend.pbitFilesExtractDir
: Specifies the local directory where extracted .pbit files will be stored for processing.
