Ping Continuously like Ping in CMD Using Node.Js

I want to use node.js to ping a host on a 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 runs once (ping). All I want is to ping constantly. 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:

Well, the obvious answer is:

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);
});


This will ping every node in the array host2

once per second.
