I'm doing an application in node to get the percentage of use of the processor, I tried to get it from the module times os, but it differs a lot from what it shows in the task manager.
I have tried with this: link
EDIT: In the end I decided to use this module link to execute the command wmic cpu get loadpercentage and thus get the percentage
I can suggest you use pidusage: link Apparently it is more complicated than it seems what you are looking for.
Example of documentation:
var pusage = require('pidusage')
pusage.stat(process.pid, function(err, stat) {
expect(err).to.be.null
expect(stat).to.be.an('object')
expect(stat).to.have.property('cpu')
expect(stat).to.have.property('memory')
console.log('Pcpu: %s', stat.cpu)
console.log('Mem: %s', stat.memory) //those are bytes
})
// Unmonitor process
pusage.unmonitor(process.pid);
