Prerequisites

Alation Cloud Service Applies to Alation Cloud Service instances of Alation

Customer Managed Applies to customer-managed instances of Alation

Enhanced Connector Enhanced connectors add extended capabilities and require a separate entitlement in addition to your Alation platform license.

Before installing and configuring the Azure Data Explorer OCF connector, ensure that network connectivity is in place and that you have a Microsoft Entra ID (Azure AD) service account (service principal).

Configure Network Connectivity

Ensure that the Alation host (for customer-managed deployments) or the Alation Agent/Connector Manager host (for Agent-based connections) can reach the Azure Data Explorer cluster endpoint.

  • Allow outbound connectivity from Alation to the Azure Data Explorer cluster endpoint on the required port (typically TCP 443 for HTTPS-based connectivity).

  • If your environment uses a firewall or proxy, ensure that the required hostnames are allowed and that SSL/TLS inspection (if used) is compatible with your connectivity requirements.

Create a Microsoft Entra ID Application

Microsoft Entra ID token authentication requires a Microsoft Entra ID application registration (service principal) that Alation can use to request access tokens. See Create a Microsoft Entra ID application registration for instructions on how to create an app registration in Azure Data Explorer.

Collect the following values for configuration in Alation:

  • Tenant ID — Microsoft Entra ID directory identifier.

  • Client ID — application (client) ID of the app registration.

  • Client secret — secret value generated during the app registration.
