/AWS1/CL_GG2SYSTEMRESRCLIMITS

Contains information about system resource limits that the IoT Greengrass Core software applies to a component's processes. For more information, see Configure system resource limits for components.

CONSTRUCTOR

IMPORTING

Optional arguments:

iv_memory TYPE /AWS1/GG2MEMORY /AWS1/GG2MEMORY

The maximum amount of RAM, expressed in kilobytes, that a component's processes can use on the core device.

iv_cpus TYPE /AWS1/RT_DOUBLE_AS_STRING /AWS1/RT_DOUBLE_AS_STRING

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 IoT Greengrass Core software doesn't limit the component's CPU usage.

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.
