processStats

Collect memory statistics about the system as well as the current process (either the main process or any renderer process)

import {processStats} from 'electron';

processStats.getProcessMemoryInfo();
>>> Object {workingSetSize: 86052, peakWorkingSetSize: 92244, privateBytes: 25932, sharedBytes: 60248}

Methods

The processStats has the following methods:

getProcessMemoryInfo()

Return an object giving memory usage statistics about the current process. Note that all statistics are reported in Kilobytes.

• workingSetSize - The amount of memory currently pinned to actual physical RAM
• peakWorkingSetSize - The maximum amount of memory that has ever been pinned to actual physical RAM
• privateBytes - The amount of memory not shared by other processes, such as JS heap or HTML content.
• sharedBytes - The amount of memory shared between processes, typically memory consumed by the Electron code itself

getSystemMemoryInfo()

Return an object giving memory usage statistics about the entire system. Note that all statistics are reported in Kilobytes.

• total - The total amount of physical memory in Kilobytes available to the system
• free - The total amount of memory not being used by applications or disk cache

On Windows / Linux:

• swapTotal - The total amount of swap memory in Kilobytes available to the system
• swapFree - The free amount of swap memory in Kilobytes available to the system
