Configure the Azure Data Explorer data source

To configure ADX for using this data source:

1. Create an Azure Active Directory (AAD) Application and AAD Service Principal.
2. In the Azure Data Explorer WebExplorer, connect the AAD Application to an Azure Data Explorer database user.
3. Use the AAD Application to configure the data source connection in Grafana.
4. (Optional) To use the dropdown cluster select when creating queries, add reader access to the subscription(s) that contain the clusters.

Creating an Azure Active Directory Service Principal

For detailed instructions on how to set up a Microsoft Entra application and service principal that can access resources, please follow this guide from Microsoft: [Create a Microsoft Entra application and service principal that can access resources](https://docs.microsoft.com/en-us/azure/azure-resource-manager/resource-group-create-service-principal-portal)

An alternative way to create an AAD application is with the Azure CLI. For more information on the Azure CLI command, refer to [az ad sp create-for-rbac](https://docs.microsoft.com/en-us/cli/azure/ad/sp?view=azure-cli-latest#az-ad-sp-create-for-rbac):

az ad sp create-for-rbac -n "http://url.to.your.grafana:3000"

This should return the following:

{
  "appId": "XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX",
  "displayName": "azure-cli-2018-09-20-13-42-58",
  "name": "http://url.to.your.grafana:3000",
