Transit Gateway metrics

AWS Transit Gateways connect your Amazon Virtual Private Clouds (VPCs) and on-premises networks through a central hub, acting as highly scalable cloud routers — each new connection is made only once. This connection simplifies your network and puts an end to complex peering relationships.Ensure your cloud platform is configured in SolarWinds Observability SaaS to collect this service's data. See Add an AWS cloud account. CloudWatch metrics must also be enabled for this service in the AWS Console for the metric data to be available.

Many of the collected metrics from AWS Transit Gateway entities are displayed as widgets in SolarWinds Observability explorers; additional metrics may be collected and available in the Metrics Explorer. You can also create an alert for when an entity's metric value moves out of a specific range. See Entities in SolarWinds Observability SaaS for information about entity types in SolarWinds Observability SaaS.

The following table lists some of the metrics collected for these entities. To see the AWS Transit Gateway metrics in the Metrics Explorer, type AWS.TransitGateway in the search box.

Metric Units Description
sw.metrics.healthscore Percent (%)

Health state. The health state provides real-time insight into the overall health and performance of your monitored entities. The health state is determined based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health state is displayed as one of the following four states and colors: Good, Moderate, Bad, or Unknown. You can determine the impact of the alerts, anomalies, and statuses on the health of an entity type by going to Settings > Health, and selecting a specific entity type. You can also customize the impact.

To view the health of AWS Transit Gateway entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select awstransitgateway.
