To add a credential for Amazon Athena,

Navigate to Credentials and click + New Credential.
Under Namespace, select a namespace where the resources will be created.
For Credential Type, select AWS Athena Credential.
Fill in the credential parameter fields. Refer to the Athena Credential Parameters table.
Check Use for catalog to automatically discover credentials and add them to the catalog page.
Click Create.
Validio will validate the connection to the Athena account. If validation passes, Validio will automatically start fetching data. If validation fails, check that you provided the correct parameter values and try again.

Once the credential is created, you can add a source to monitor Athena data.
