How to get CPU and memory consumption in Total.js?

it will work in Linux and macOS
operations are supported in Total.js +v2.4.0.

Create an operation

The operation below reads CPU and RSS (memory) information from terminal, it's the information from the operation system.

E.g. /definitions/operations.js:

const Exec = require('child_process').exec;

NEWOPERATION('consumption', function(error, value, callback) {
    var async = [];
    var output = { cpu: 0, rss: 0 };
    Exec('ps -p {0} -o %cpu,rss,etime'.format(process.pid), function(err, response) {
        err && error.push(err);
        response.parseTerminal(['%CPU', 'RSS'], function(line) {
            output.cpu = U.parseFloat(line[0]);
            output.rss = U.parseFloat(line[1]) * 1024; // bytes
        });
        callback(output);
    });
});

Usage

You can execute the code below anywhere in your Total.js application:

OPERATION('consumption', function(err, response) {
    console.log(err, response.cpu + '%', response.rss.filesize();
    // null '24.3%' '40.45 MB'
});
