## Viewing data sources
<a name="telemetry-config-view-data-sources"></a>

The **Ingestion – Data sources** shows the Amazon resources that you can send to CloudWatch. For specific resource types, it shows the percentage of resources with telemetry configured and the total number of resources detected. You can filter the display of resources in the **Data source** tab by account ID or by the tags applied to your resources.

**To view resources on the **Ingestion** page**

1. Open the CloudWatch console at [https://console.amazonaws.cn/cloudwatch/](https://console.amazonaws.cn/cloudwatch/).

1. In the navigation pane, choose **Ingestion**.

1. The **Ingestion** page shows the total number of each resource that was discovered by CloudWatch, the number of resources providing telemetry, and the percentage of discovered resources that are providing telemetry.

1. To see recent changes to resources, choose **Refresh**.

## Viewing discovered resources
<a name="telemetry-config-view-discovered"></a>

The **Discovered resources** page shows details about each Amazon resource that has been discovered by telemetry configuration, including the resource ID, the type of telemetry each resource is providing, and the time when information about the resource was last refreshed.

For each Amazon resource tracked by CloudWatch, the **Discovered resources** page shows the status of its telemetry by providing the following information:
+ For telemetry types that CloudWatch detects that the resource is sending to CloudWatch, the **Discovered resources** page shows **On**.
+ For telemetry types that CloudWatch detects the resource is not providing, the **Discovered resources** page shows **Off**.
+ For telemetry types that are not supported for a resource, the **Discovered resources** page shows **NS**, that is, not supported.

**To view resources on the **Discovered resources** page**

1. Open the CloudWatch console at [https://console.amazonaws.cn/cloudwatch/](https://console.amazonaws.cn/cloudwatch/).

1. In the navigation pane, choose **Ingestion**.

1. Do one of the following to view all resource types discovered by telemetry configuration or to view one resource type:

   1. To view all resources that have been discovered by CloudWatch, click **View data sources**. The **Discovered resources** page appears and shows all resources discovered.

   1. To view one resource type, click the name of the Amazon resource type in the **Ingestion > Data sources**. The **Discovered resources** page appears. The **Discovered resources** page shows that a filter has been applied for that data source and now displays all discovered resources for that resource type.

1. On the **Discovered resources** page, to view information about the resource or to change its telemetry settings, click the resource ID. The console page for the Amazon resource will open, navigate to the configuration setting and turn on or off the configuration.
**Note**  
You can only view a resource on its console page if the resource belongs to your account. To determine if the resource belongs to your account, check the **Amazon Web Services account** column. If the **Amazon Web Services account** column does not appear, change your **Discovered resources** page preferences. For more information, see [Changing preferences for the Discovered resources page](#telemetry-config-resource-view-prefs).

### Viewing resources across Regions
<a name="telemetry-config-view-multi-region"></a>

When multi-Region support is active, the **Discovered resources** page includes a **Region** column. You can filter resources by Region to focus on specific Regions.

CloudWatch uses a Amazon Config aggregator to collect resource data across Regions. Because of this, there may be a short delay before resources from spoke Regions appear in the home Region view.

## Filtering and preferences
<a name="telemetry-config-filter-resource-view"></a>

You can use one or more filters on the **Ingestion > Data Sources** page and the **Discovered resources** page to change your view of the resources. Your filter settings persist across both pages.

**To filter resources on the **Data Sources** page**

1. Open the CloudWatch console at [https://console.amazonaws.cn/cloudwatch/](https://console.amazonaws.cn/cloudwatch/).

1. In the navigation pane, choose **Ingestion**, and then choose **Data sources**.

1. You can filter the discovered resources that are displayed on the page by specifying an account ID or tag value.

   1. Choose **Find resource**.

   1. Choose **Account ID** or **Tag value**, and then choose additional options for the filter. Statistics about telemetry coverage for each resource change based on your filter options.

1. To remove a filter, in the filter text box, choose **X**.
