Deno.loadavg

Unstable There are questions around which permission this needs. And maybe should be renamed (loadAverage?)

Returns an array containing the 1, 5, and 15 minute load averages. The load average is a measure of CPU and IO utilization of the last one, five, and 15 minute periods expressed as a fractional number. Zero means there is no load. On Windows, the three values are always the same and represent the current load, not the 1, 5 and 15 minute load averages.

console.log(Deno.loadavg());  // e.g. [ 0.71, 0.44, 0.44 ]

Requires allow-env permission.
