Viewing Grafana Data in RAD Studio Data Explorer

Embarcadero RAD Studio provides a development environment for Delphi and C++Builder applications. With the CData ODBC Driver for Grafana, you gain access to live Grafana data within RAD Studio, abstracting the data into tables, views, and stored procedures that can be used to both retrieve Grafana data. This article will walk through connecting to Grafana using the Data Explorer.

Configure a Connection to Grafana

If you have not already, first specify connection properties in an ODBC DSN (data source name). This is the last step of the driver installation. You can use the Microsoft ODBC Data Source Administrator to create and configure ODBC DSNs.

Start by setting the Profile connection property to the location of the Grafana Profile on disk (e.g. C:\profiles\Grafana.apip). Next, set the ProfileSettings connection property to the connection string for Grafana (see below).

Grafana API Profile Settings

In Grafana, navigate to Administration > Users and Access > Service accounts, create a service account, then click Add service account token to generate a token.

Connecting to Grafana Data Using Data Explorer

You can create a simple application for displaying Grafana data by utilizing the CData FireDAC Components for Grafana and a new VCL Forms Application:

1. Open the Data Explorer in RAD Studio and expand FireDAC.
2. Right-click the ODBC Data Source node in the Data Explorer.
3. Click Add New Connection. 👁 Adding a New Connection. (Salesforce is shown.)
   
4. Enter a name for the connection.
5. In the FireDAC Connection Editor that appears, set the DataSource property to the name of the ODBC DSN for Grafana. 👁 Setting the Connection Parameters. (Salesforce is shown.)
   
6. Back in the Data Explorer, expand the views for the connection.

7. Create a new VCL Forms application and drag a view (for example: Alert) onto the form.

   👁 Placing the View on the Form. (Salesforce is shown.)
   
8. Select the AlertView object on the form and set the Active property to true.

9. Right-click on the object, bind visually, and link everything (*) to a new control (TStringGrid).

   👁 Visually Binding the View. (Salesforce is shown.)
   

10. Arrange the TStringGrid on the form and run the application to see the Alert data.

    👁 The View data on a Form. (Salesforce is shown.)
