This project checks a number of backends, if they are able to connect and do a simple action, e.g. check out the django ORM backend:

class DjangoDatabaseBackend(BaseHealthCheckBackend):

    def check_status(self):
        try:
            obj = TestModel.objects.create(title="test")
            obj.title = "newtest"
            obj.save()
            obj.delete()
            return True
        except IntegrityError:
            raise ServiceReturnedUnexpectedResult("Integrity Error")
        except DatabaseError:
            raise ServiceUnavailable("Database error")

The project is made using some of the same codes, that the django admin site uses - so when you have sucessfully written a new plugin, you register it to the pool, e.g.

plugin_dir.register(DjangoDatabaseBackend)

Add this to urls.py

url(r'^ht/', include('health_check.urls'))

Add required apps:

    'health_check',
    'health_check_celery',
    'health_check_db',
    'health_check_cache',
    'health_check_storage',

(remember to add dependencies, e.g. djcelery - however you should have that already, if you have celery running). You'll also have to make sure that you have a result backend <http://celery.readthedocs.org/en/latest/configuration.html?highlight=result_backend#std:setting-CELERY_RESULT_BACKEND>_ configured. If you are using celery 3, use health_check_celery3 instead of health_check_celery.

E.g. add to pingdom - django-health-check will return HTTP 200 if everything is OK and HTTP 500 if anything is not working.
