Once you’ve integrated with AWS CloudWatch, you have access to metrics from AWS EC2 Auto Scaling, which ensures you have the appropriate number of Amazon EC2 instances to manage the load for your application available.
You can create a pre-built dashboard for this integration when you add the integration to Cloud Observability or from the Dashboard list view.
You can validate that metrics are reporting to Cloud Observability on the Metrics details page in Settings.
The following table shows the EC2 Auto Scaling metrics ingested by Cloud Observability.
| Metric Name | Unit | Description |
|---|---|---|
| aws.autoscaling.group_min_size | count | The minimum size that the Auto Scaling group can be. |
| aws.autoscaling.group_max_size | count | The maximum size that the Auto Scaling group can be. |
| aws.autoscaling.group_desired_capacity | count | The number of instances the Auto Scaling group tries to keep. |
| aws.autoscaling.group_in_service_instances | count | The number of instances that the Auto Scaling group has running. |
| aws.autoscaling.group_pending_instances | count | The number of pending instances. An instance that is pending is not yet active. |
| aws.autoscaling.group_standby_instances | count | The number of instances that are in the Standby state. |
| aws.autoscaling.group_terminating_instances | count | The number of instances that are being terminated. |
| aws.autoscaling.group_total_instances | count | The total number of instances in the Auto Scaling group as a whole. |
| aws.autoscaling.group_in_service_capacity | count | The number of capacity units that the Auto Scaling group has active. |
| aws.autoscaling.group_pending_capacity | count | The number of pending capacity units. |
| aws.autoscaling.group_standby_capacity | count | The number of capacity units that are in Standby. |
| aws.autoscaling.group_terminating_capacity | count | The number of capacity units that are about to be terminated. |
| aws.autoscaling.group_total_capacity | count | The total number of capacity units in the Auto Scaling group as a whole. |
| aws.autoscaling.warm_pool_min_size | count | The minimum size of the warm pool. |
| aws.autoscaling.warm_pool_desired_capacity | count | The amount of capacity in the warm pool that Amazon EC2 Auto Scaling tries to maintain. |
| aws.autoscaling.warm_pool_pending_capacity | count | The pending quantity of the warm pool's capacity. |
| aws.autoscaling.warm_pool_terminating_capacity | count | The amount warm pool's current capacity, which is being shut down. |
| aws.autoscaling.warm_pool_warmed_capacity | count | The amount of capacity that is accessible to join the Auto Scaling group during scale out. |
| aws.autoscaling.warm_pool_total_capacity | count | The warm pool's overall capacity, which takes into account instances that are active, inactive, awaiting, or terminating. |
| aws.autoscaling.group_and_warm_pool_desired_capacity | count | The combined desired capacity of the warm pool and the Auto Scaling group. |
| aws.autoscaling.group_and_warm_pool_total_capacity | count | The total combined capacity of the warm pool and the Auto Scaling group. |
