# Access AWS Cloud WAN transit gateway dashboards Access transit gateway dashboards View dashboard information about transit gateways registered in your AWS Cloud WAN global network. For more information about the Cloud WAN transit gateway dashboards see [Cloud WAN transit gateway dashboards](cloudwan-visualize-tgw.md#cloudwan-dashboard-tgw). **Topics** + [ ## Overview ](#cloudwan-tgws-overview) + [ ## Topology tree ](#cloudwan-tgws-topolgy-tree) + [ ## Events ](#cloudwan-tgws-events) + [ ## Monitoring ](#cloudwan-tgws-monitoring) + [ ## On-premises associations ](#cloudwan-tgws-on-premises) + [ ## Connect peer ](#cloudwan-tgws-connect-peer) ## Overview The **Overview** page displays details about your transit gateways, their VPN, their Connect peer status, and any network events affecting the transit gateway. **To view transit gateway details** 1. Access the Network Manager console at [https://console.aws.amazon.com/networkmanager/home/](https://console.aws.amazon.com/networkmanager/home). 1. Under **Connectivity**, choose **Global Networks**. 1. On the **Global networks** page, choose the global network link. 1. In the navigation pane, choose **Transit Gateways**. 1. On the **Transit gateways** page, choose the **ID** link that you want to view the dashboard for. 1. The **Overview** page opens by default. 1. On the **Overview** page, you can view the following sections: + The **Transit Gateway** details section displays the transit gateway **ID**, **Name**, **Region**, and **State**. Choose a different transit gateway to view those details. + The **Attachments** section shows the number of each resource attached to the transit gateway. The following legend describes the attachments: [\[See the AWS documentation website for more details\]](http://docs.aws.amazon.com/network-manager/latest/cloudwan/cloudwan-tgw-dashboard.html) + The **VPNs** section displays the VPN **ID**, **Device**, **Link**, **VPN status**, and **Tunnel status**. + The **Connect peers** section displays the Connect peer **ID**, **Device**, **Link**, **Status**, and **BGP status**. + The **Network events summary** displays events and the number of core network attachments per edge, shown as a stacked column chart. (Optional) Metrics and events use the default time set up in the CloudWatch Events event. To set a custom time frame, choose **Custom** and then choose a **Relative** or **Absolute** time, and then choose if you want to see that date range in **UTC** or the edge location's **Local time zone**. Choose **Add to dashboard** to add this metric to your CloudWatch dashboard. For more information about using CloudWatch dashboards, see [Using Amazon CloudWatch Dashboards](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Dashboards.html) in the *Amazon CloudWatch User Guide*. **Note** The **Add to dashboard** option only works if your registered transit gateway is in the US West (Oregon) Region. ## Topology tree The **Topology tree** page shows a logical diagram of each AWS Transit Gateway. **To access the topology tree for a transit gateway** 1. Access the Network Manager console at [https://console.aws.amazon.com/networkmanager/home/](https://console.aws.amazon.com/networkmanager/home). 1. Under **Connectivity**, choose **Global Networks**. 1. On the **Global networks** page, choose the global network link. 1. In the navigation pane, choose **Transit Gateways**. 1. On the **Transit gateways** page, choose the **ID** link that you want to view the dashboard for. 1. The **Overview** page opens by default. 1. Choose the **Topology tree** tab. 1. By default, the **Topology tree** page displays the **Sites**, **Devices**, and **Customer Gateways** of the chosen transit gateway and the logical relationships between them. You can filter the network tree to show specific resources types to view information about the specific resource represented. The line colors represent the state of the relationships between AWS and the on-premises resources. ## Events Track your transit gateway **Events** using Amazon EventBridge, which delivers a near-real-time stream of system events that describe changes in your resources. Using simple rules that you can quickly set up, you can match events and route them to one or more target functions or streams. For more information, see the [Amazon EventBridge User Guide](https://docs.aws.amazon.com/eventbridge/latest/userguide/). **To track transit gateway events** 1. Access the Network Manager console at [https://console.aws.amazon.com/networkmanager/home/](https://console.aws.amazon.com/networkmanager/home). 1. Under **Connectivity**, choose **Global Networks**. 1. On the **Global networks** page, choose the global network link. 1. In the navigation pane, choose **Transit Gateways**. 1. On the **Transit gateways** page, choose the **ID** link that you want to view the dashboard for. 1. The **Overview** page opens by default. 1. Choose the **Events** tab. The **Events** section updates with the events that occurred during the time frame for the chosen transit gateway. (Optional) Metrics and events use the default time set up in the CloudWatch Events event. To set a custom time frame, choose **Custom** and then choose a **Relative** or **Absolute** time, and then choose if you want to see that date range in **UTC** or the edge location's **Local time zone**. Choose **Add to dashboard** to add this metric to your CloudWatch dashboard. For more information about using CloudWatch dashboards, see [Using Amazon CloudWatch Dashboards](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/CloudWatch_Dashboards.html) in the *Amazon CloudWatch User Guide*. **Note** The **Add to dashboard** option only works if your registered transit gateway is in the US West (Oregon) Region. ## Monitoring On the **Monitor** page, monitor your transit gateways using Amazon CloudWatch, which collects raw data and processes it into readable, near-real-time metrics. These statistics are kept for 15 months, so that you can access historical information and gain a better perspective on how your network is performing. You can also set alarms that watch for certain thresholds, and send notifications or take actions when those thresholds are met. For more information, see the [Amazon CloudWatch User Guide](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/). On the monitoring page, you can view usage metrics for your transit gateways, filtering by specific transit gateways. **To access transit monitoring details** 1.
