This topic explains how warehouse health checks help you troubleshoot connection errors with your warehouse Data Export destinations, including BigQuery, ClickHouse, Redshift, and Snowflake.

Warehouse health checks evaluate three conditions:

* Whether the Data Export destination for a given project and environment is receiving data
* Whether required fields are present and valid
* Whether authentication to your warehouse is working

LaunchDarkly shows warehouse health warnings at the top of the **Integrations** page if there are any connection problems, and within the integrations section for individual warehouse Data Export connections:

## View connection status

To view the connection status for an integration:

1. Click the **gear** icon in the left sidebar to open Organization settings.
2. Click **Integrations**.
3. Find your warehouse Data Export integration section and click the **down arrow** next to "Add integration." A list of existing destinations displays.

Each warehouse Data Export integration can display one of the following connection statuses:

* **Connected**: The integration is enabled and operating normally.
* **Connected with errors**: The integration is enabled but LaunchDarkly detected a problem, such as data delivery errors.
* **Disconnected**: The integration is not connected. You may need to update your credentials or complete setup for the integration.

To view more information about a connection error, click the **pencil** icon next to the error to open the integration configuration panel. A warning message displays with information about the error:

For destinations that authenticate using an AWS IAM role, such as Redshift and ClickHouse, the most common cause of an initial connection failure is IAM role propagation. After you create a role in AWS, the `sts:AssumeRole` action can take up to five minutes to be reachable from another AWS account. If your first **Test connection and save** fails immediately after you create the role, wait a few minutes and try again. To learn more, read [Redshift Data Export](/docs/integrations/data-export/redshift#test-and-save-the-connection).
