TAO dashboard is showing no data

    If you're experiencing issues with your Trusted Advisor Organizational (TAO) dashboard showing no data, there are a few things you can check and try:

    1. Ensure you have active assessments: The dashboard requires at least one active assessment to display data. If you haven't created any assessments yet, you'll need to do so. After creating an assessment, it typically takes about 24 hours for the data to start appearing in the dashboard.

    2. Verify QuickSight setup: Make sure your Amazon QuickSight account is properly set up and has the necessary permissions to access the Athena data source. You may need to create a new Athena data source in QuickSight, pointing to the correct database and table.

    3. Check QuickSight datasets: In QuickSight, verify that the datasets are configured correctly and are able to import data. You might need to initiate a manual dataset refresh for each dataset in QuickSight.

    4. Review CloudFormation stack: Double-check that your CloudFormation stacks in both the management and data collection accounts were deployed successfully without any errors.

    5. Confirm S3 bucket permissions: Ensure that QuickSight has the necessary permissions to access the S3 bucket where your Trusted Advisor data is stored.

    6. Wait for data propagation: Even after running the update command, it may take some time for the data to propagate through the system and appear in the dashboard. Give it some time (up to 24 hours) and check again.

    7. Verify Athena tables and views: Check the Glue console to ensure that the necessary databases, tables, and views have been created correctly in the Glue Catalog. These should match what you see in Athena.

    If you've verified all these points and are still not seeing data in your dashboard, you may need to consider tearing down the deployment and rebuilding it, following the instructions provided in the AWS CID workshop documentation.
