Global memory

The information refer to the system's global memory

Original source

The global memory information are retrieved from the MacOsGlobalMemory interface, which inherits GlobalMemory

val globalMemory: MacOsGlobalMemory = hardware.globalMemory

Retrieve hardware as shown in the Hardware API. The values are collected by separate native queries

Warning

Reading globalMemory throws an IllegalStateException when the required swap usage or swap page statistics cannot be read

The total physical memory in bytes, or 0 when the native query fails

val total: Long = globalMemory.total

println(total) // e.g. 17179869184

The estimated available memory in bytes, calculated from free and inactive pages. A failed native query returns 0

val available: Long = globalMemory.available

println(available) // e.g. 4294967296

The system's memory page size in bytes, or 0 when the native query fails

val pageSize: Long = globalMemory.pageSize

println(pageSize) // e.g. 16384

The virtual memory and swap statistics

val virtualMemory: VirtualMemory = globalMemory.virtualMemory

println(virtualMemory)

List of physical memory entries. On Apple Silicon, the list describes unified memory rather than separate removable modules

val physicalMemory: List<PhysicalMemory> = globalMemory.physicalMemory

println(physicalMemory)
