CloudWatch metrics in AWS Cloud WAN
You can use the following features to monitor your Cloud WAN network, analyze traffic patterns, and troubleshoot issues with your Cloud WAN global network.
Cloud WAN metrics and dimensions
You can use metrics to verify that your system is performing as expected. For example, you can create a CloudWatch alarm to monitor a specified metric and initiate an action (such as sending a notification to an email address) if the metric goes outside what you consider an acceptable range.
Amazon VPC measures and sends its metrics to CloudWatch in 60-second intervals.
For more information, see the Amazon CloudWatch User Guide.
The AWS/NetworkManager namespace includes the following metrics. All
metrics are always reported.

Cloud WAN metric dimensions
Filter metric data by a combination of the following Cloud WAN core network metric dimensions.
| Dimension | Description |
|---|---|
CoreNetwork, EdgeLocation |
Filters the metric data by core network. |
Attachment, CoreNetwork |
Filters the metric data by core network attachment. |
AvailabilityZone, CoreNetwork,
EdgeLocation |
Filters the metric data by availability zone. This is only applicable for Direct Connect. |
Attachment, AvailabilityZone,
CoreNetwork |
Filters the metric data by both core network attachment and availability zone. |
AWS Cloud WAN usage metrics
Cloud WAN usage metrics correspond to AWS service quotas for Cloud WAN. You can configure alarms that alert you when your usage approaches a service quota. For more information about CloudWatch integration with service quotas, see CloudWatch usage metrics in the Amazon CloudWatch User Guide.
The AWS/Usage namespace reports the following metric for Cloud
WAN:
| Metric | Description |
|---|---|
ResourceCount |
The number of the specified resources running in your account. The
resources are defined by the dimensions associated with the
metric. Statistics: The only
meaningful statistic is |
AWS Cloud WAN metric dimensions
The following dimensions are used to refine the usage metrics that are published by Cloud WAN.
| Dimension | Description |
|---|---|
Service |
The name of the AWS service containing the resource. For
Cloud WAN usage metrics, the value for this dimension is
NetworkManager. |
Type |
The type of entity that is being reported. Currently, the only
valid value for Cloud WAN usage metrics is
Resource. |
Resource |
The type of resource that is running. Currently, valid values for
Cloud WAN usage metrics include
RoutesPropagated/Inbound and
RoutesPropagated/Outbound, which return the number
of routes advertised and learnt over Direct Connect
attachments. |
ResourceID |
The unique identifier for the resource, such as a core network attachmentId, and might include a region code prefix for region-specific resources. |
Class |
This dimension is reserved for future use. |
