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

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

System Message: WARNING/2 (<string>, line 48); backlink

Inline literal start-string without end-string.

System Message: WARNING/2 (<string>, line 48); backlink

Inline interpreted text or phrase reference start-string without end-string.

'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.
