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.
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.
But maybe there is something more advanced out there ?
