AWS::GreengrassV2::Deployment SystemResourceLimits

Contains information about system resource limits that the software applies to a component's processes.

Syntax

To declare this entity in your AWS CloudFormation template, use the following syntax:

JSON

{
  "Cpus" : Number,
  "Memory" : Integer
}

YAML

  Cpus: Number
  Memory: Integer

Properties

Cpus

The maximum amount of CPU time that a component's processes can use on the core device. A core device's total CPU time is equivalent to the device's number of CPU cores. For example, on a core device with 4 CPU cores, you can set this value to 2 to limit the component's processes to 50 percent usage of each CPU core. On a device with 1 CPU core, you can set this value to 0.25 to limit the component's processes to 25 percent usage of the CPU. If you set this value to a number greater than the number of CPU cores, the AWS IoT Greengrass Core software doesn't limit the component's CPU usage.
