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.
Project description
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).
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``.
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.
Profit
