NAT Gateway metrics
AWS NAT gateways are Network Address Translation (NAT) services. You can use a NAT gateway so that instances in a private subnet can connect to services outside your VPC but external services cannot initiate a connection with those instances. 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 NAT 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 AWS.NATGateway in the search box.

Health score. A health score provides real-time insight into the overall health and performance of your monitored entities. The health score is calculated based on anomalies detected for the entity, alerts triggered for the entity's metrics, and the status of the entity. The health score is displayed as a single numerical value that ranges from a Good (70-100) to Moderate (40-69) to Bad (0-39) distinction.
