Auto Scaling Group metrics

Amazon Auto Scaling Groups help you maintain application availability and allow you to dynamically scale your Amazon EC2 capacity up or down automatically according to conditions you define. 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 Auto Scaling Group 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 Auto Scaling Group metrics in the Metrics Explorer, type AWS.AutoScaling in the search box.

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

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.

To view the health score for AWS Auto Scaling Group entities in the Metrics Explorer, filter the sw.metrics.healthscore metric by entity_types and select awsautoscalinggroup.
