django-health-check 0.3

a pluggable app that runs a full check on the deployment, using a number of plugins to check e.g. database, queue server, celery processes, etc.

django-health-check
==================

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:


```python

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.

```python
plugin_dir.register(DjangoDatabaseBackend)
```


Install
=======

Add this to urls.py

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

Add required apps:

```python
'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)

Set up monitoring
=================

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