Visualize AWS Cloud WAN core networks

The AWS Cloud WAN console provides a dashboard where you can visualize and monitor your global network. It includes information about the resources in your global network, their geographic locations, the network topology, and the logical network associations.

Overview

On the AWS Cloud WAN console Overview page, you can view the following information:

• Your core network resource inventory.

• The location of core network edges and transit gateways within your global network, displayed as icons on a map. Connections are shown between resources.

• Throughput information between core network edges.

• The number of core network attachments per edge, shown as a stacked column chart. You can filter this chart to display specific attachment types.

Use the following legend to understand the icons on your core network map:

Icon	Description
	Edge locations The total number of edge locations in your core network. The number is shown in the Inventory section and as an icon on the map for each edge location in your core network.
	Segments The total number of segments in your core network. The number is shown in the Inventory section and as an icon on the map for each section in your core network.
	Devices The total number of devices in your core network. The number is shown in the Inventory section and as an icon on the map for each device in your core network.
	Sites The total number of sites in your core network. The number is shown in the Inventory section and as an icon on the map for each site in your core network.

To view the core network map

1. Access the Network Manager console at https://console.aws.amazon.com/networkmanager/home/.

2. Under Connectivity, choose Global Networks.

3. On the Global networks page, choose the global network ID.

4. In the navigation pane, choose Core network.

5. The Overview page opens by default.

6. The Inventory section shows information about your core network: the number of Edge locations in your core network, the number of Segments, the number of Devices, and the number of Sites.

7. The Geography section displays a world map with the locations of your resources.

8. The Throughput section shows throughput information between the core network edges.

   • (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 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.

9. The Attachment section displays information about each attachment for each core network edge location. Choose the Filter by attachment type dropdown list. By default all attachment types are chosen. Clear the check box for any attachment type that you don't want to include in the graph. You can filter by any combination of:

The Logical page shows a logical representation of the segments in your core network. You can filter by a specific source or destination segment, or by a source or destination attachment. You can view the network tree for your global network, which includes core network and transit gateway networks. By default, the page displays all resources in your global network and the logical relationships between them. You can filter the network tree to show specific on-premises resource types only. For example, the preceding image shows sites and devices, and excludes customer gateways. You can choose any of the nodes to view information about the specific resource that it represents. The line colors represent the state of the relationships between AWS and any on-premises resources.

   • Route state — The current state of a route. This will be either ACTIVE or BLACKHOLE.

Events

You can monitor your core network using CloudWatch Events, 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 about CloudWatch Events, see the Amazon CloudWatch Events User Guide.

Prerequisites: Before monitoring CloudWatch Events you must first onboard CloudWatch Logs Insights. This is a one-time process that needs to be completed at the account level. After this is set up for your core network, you'll be able to see event updates on this page. For more information on AWS Cloud WAN events, see AWS Cloud WAN Events and metrics.

To access core network events

1. Access the Network Manager console at https://console.aws.amazon.com/networkmanager/home/.

2. Under Connectivity, choose Global Networks.

3. On the Global networks page, choose the global network ID.

4. In the navigation pane, choose Core network.

5. The Overview page opens by default.

6. Choose the Events tab.

   The Events section updates with the CloudWatch events that occurred during the selected time frame.

7. (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 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.

8. In the following example, the Events section shows two events occurring within a custom 15-month time frame:

   • A change set was executed successfully for a core network policy update.

   • An edge location was added to the core network.

   

   For a full list of tracked events, see Monitor with CloudWatch Events.

Monitoring

You can monitor your core network by 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 Events User Guide.

On the monitoring page you can view usage metrics for your core network, filtering by specific edge locations.

To access core network monitoring details

1. Access the Network Manager console at https://console.aws.amazon.com/networkmanager/home/.

2. Under Connectivity, choose Global Networks.

3. On the Global networks page, choose the global network ID.

4. In the navigation pane, choose Core network.

5. The Overview page opens by default.

6. Choose the Monitoring tab.
