How to get around the asynchronous Node.js behaviour?

I'm working on a script that pings websites and returns the results in a web UI. However, I've run into a problem which I am trying to figure out the best solution for.

This block of code needs to return a array of statuses but due to the asynchronous behaviour of Node.js, it returns an empty array because the code takes time to execute.

Here is what I have:

var ping = require('ping');

function checkConnection(hosts) {

    var results = [];

    hosts.forEach(function (host) {
        ping.sys.probe(host, function (isAlive) {
            results.push({"host": host, "status": isAlive});
        });
    });

    return {results: results, timestamp: new Date().getTime()};
}

module.exports.checkConnection = checkConnection;

I know that you could solve this problem with the use of timers but what would be the simples and most ideal solution here?
