Ping Continuously Like Ping in CMD Using Node.Js

Question

I want use node.js to ping host in local network. Here is my code :

var ping = require('ping');

var host2 = ['192.168.0.1', '192.168.1.2', '192.168.2.3'];

host2.forEach(function(host){
    ping.sys.probe(host, function(active){
        var info = active ? 'IP ' + host + ' = Active' : 'IP ' + host + ' = Non-Active';
        console.log(info);
    });
});

This code only run (ping) once. All I want is to ping continuously. Is this possible with node.js?

EDIT : When I run the code :

EDIT 2 : When using setInterval / setTimeout :

Code :

var ping = require('ping');

var host2 = ['192.168.0.1', '192.168.1.2', '192.168.2.3'];

host2.forEach(function(host){
    ping.sys.probe(host, function tes(active){
        var info = active ? 'IP ' + host + ' = Active' : 'IP ' + host + ' = Non-Active';
        console.log(info);
    });
    setInterval(tes, 2000);
});

Result :

Answer 1

Well the obvious answer is this:

var ping = require('ping');

var host2 = ['192.168.0.1', '192.168.1.2', '192.168.2.3'];

var frequency = 1000; //1 second

host2.forEach(function(host){
    setInterval(function() {
        ping.sys.probe(host, function(active){
            var info = active ? 'IP ' + host + ' = Active' : 'IP ' + host + ' = Non-Active';
            console.log(info);
        });
    }, frequency);
});

That will ping each host in the host2 array once every second.
