I'm not sure why you're using that array structure. If you made it yourself, I suggest you remove the "monitor" array, and move the content of it into "monitors"

Anyways, Lets say your array is named $monitors

foreach($monitors['monitors'] as $k => $v) { 
    foreach($v['monitor'] as $monitor) { 

         echo "monitor id: " . $monitor['id'] . "<br>\n";
         echo "friendly name: " . $monitor['friendlyname'] . "<br>\n";
    }
}

And get date time for monitor id:

function getLogById($monitors, $id) {
    foreach($monitors['monitors'] as $k => $v) { 
        foreach($v['monitor'] as $monitor) { 
            if($monitor['id'] == $id) {
                //Depending on what you exactly want returned, do something here
                return $monitor['log'];
            }
        }
    }

    return null;
}

//and you can use this like so:
getLogById($monitors, 778539794);
