AWS OpsWorks Stacks helps manage applications and servers on AWS and on-premises. Every Opsworks stack contains one or more layers, each of which represents a stack component, such as a load balancer or a set of application servers.
When working with AWS OpsWorks Stacks layers, keep the following in mind:
- Each layer in a stack must have at least one instance and can optionally have multiple instances.
- Each instance in a stack must be a member of at least one layer, except for registered instances.
- Instances cannot be configured directly, except for some basic settings such as the SSH key and hostname. You must create and configure an appropriate layer, and add the instance to the layer.

|OpsRamp Metric||Metric Display Name||Unit||Aggregation Type|
Percentage of time that the CPU is idle.
Percentage of time that the CPU is handling processes with a positive nice value, which have a lower scheduling priority.
As AWS allocates hypervisor CPU resources among increasing numbers of instances, virtualization load rises which can affect how often the hypervisor can perform requested work on an instance. cpu_steal measures percentage of time that an instance is waiting for the hypervisor to allocate physical CPU resources.
Percentage of time that the CPU is handling system operations.
Percentage of time that the CPU is handling user operations.
Percentage of time that the CPU is waiting for input/output operations.
