title: Django - alert when memcached is down
body: <p>Is there some ready-made addon that alerts admins about memcached instance being inaccessible from a Django application? I don't mean here monitoring memcached daemon itself, but something that checks if my Django app benefits from caching.</p>
  
  <p>My basic idea is to check if cache.get that follow cache.set actually returns something, and if not - then send email to admins, but only one per hour, to not flood the inbox. </p>
  
  <p>But maybe there is something more advanced out there ?</p>
