Grafana is an open-source platform that allows users to analyze, monitor, and visualize telemetry from various data sources. When combined with CData Connect AI, you gain immediate access to OData services for business dashboards. This article outlines the process of connecting to OData using Connect AI and creating a basic dashboard from OData services within Grafana.
CData Connect AI offers a pure SQL Server, cloud-to-cloud interface for OData, enabling the creation of dashboards directly from live OData services within Grafana, all without the need for data replication to a native database. As you build visualizations, Grafana generates SQL queries to gather data. With its inherent optimized data processing capabilities, CData Connect AI efficiently channels all supported SQL operations, including filters and JOINs, directly to OData. This leverages server-side processing to swiftly deliver the requested OData services.

Add a Personal Access Token
When connecting to Connect AI through the REST API, the OData API, or the Virtual SQL Server, a Personal Access Token (PAT) is used to authenticate the connection to Connect AI. It is best practice to create a separate PAT for each service to maintain granularity of access.
-
Click on the Gear icon () at the top right of the Connect AI app to open the settings page.
-
On the Settings page, go to the Access Tokens section and click Create PAT.
-
Give the PAT a name and click Create.

-
The personal access token is only visible at creation, so be sure to copy it and store it securely for future use.
With the connection configured and a PAT generated, you are ready to connect to OData services from Grafana.
