In this section you will learn how to get information about current load, running processes and installed services:

For function reference and examples we assume, that we imported systeminformation as follows:

const si = require('systeminformation');

Current Load, Processes, Services

All functions in this section return a promise or can be called with a callback function (parameter cb in the function reference)
