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 the health for a number of backends and sees if they are able to connect and do a simple action. For example, 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 plugin code that the Django admin site uses - so when you have successfully written a new plugin, you register it to the pool, e.g.
plugin_dir.register(DjangoDatabaseBackend)Install
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, for example djcelery for Celery. You should have that already, if you have Celery running. You’ll also have to make sure that you have a result backend configured.
If you are using Celery 3, use the health_check_celery3 application 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.
Dependencies
Django 1.4+
