Select PDC and test connection

The private data source connect (PDC) feature allows you to establish a secure connection between Grafana Cloud and your Prometheus data source. If you don’t use PDC, your queries and data are transmitted over the public internet, exposing them to potential security risks.

Did you know?

We recommend that you create a private connection whenever you connect Grafana Cloud to an external data source.

In this milestone, you select an active PDC agent and test the connection to Grafana Cloud.

To select a PDC agent and test the connection, complete the following steps:

  1. In the Private data source connect field, select the name of a PDC agent.

    Did you know?

    For the test connection to be successful, you must select a PDC agent that’s running.

  2. Click Save & Test.

    When successful, you’ll see the following message:

    Successfully queried the Prometheus API.

    Next, you can start to visualize data by building a dashboard, or by querying data in the Explore view.

Were you successful?
