Method 1

After the bit of research and looking in to the Laravel source I have found way to do it.

Laravel Elouqont provides a method isDirty([])

namespace AppObservers;


use AppOnsiteHistory;

class OnsiteHistoryObserver
{

    public function updated(OnsiteHistory $onsiteHistory)
    {
        if ($onsiteHistory->isDirty(['status']) &&  strtolower($onsiteHistory->status) == 'accepted'){

       dd('I am updated')


        }
    }
}
