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

version ci coverage health license

This project checks the health for a number of backends and sees if they are able to connect and do a simple action.

plugin_dir.register(DjangoDatabaseBackend)

Install

Add this to urls.py

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

Add required apps:

'health_check',  # required
'health_check.db',
'health_check.cache',
'health_check.storage',
'health_check.contrib.celery',
'health_check.contrib.s3boto_storage',

Note

Not that you will need a result backend configured for celery.

Set up monitoring

You can use tools like Pingdom or other uptime robots. The /ht/ endpoint will respond a HTTP 200 if all checks passed and a HTTP 500 if any of the tests failed.

Writing a custom health check

Writing a health check:

class MyHealthCheckBackend(BaseHealthCheckBackend):
    def check_status(self):
        # The test code goes here.
        # You can use `self.add_error` or raise a
        # `HealthCheckException`. Similar to Django's form validation.
        pass

    def identifier(self):
        return self.__class__.__name__  # Display name on the endpoint.

Register the backend in your app configuration:

from django.apps import AppConfig

from health_check.plugins import plugin_dir


class MyAppConfig(AppConfig):
    name = 'my_app'

    def ready(self):
        from .backends import MyHealthCheckBackend
        plugin_dir.register(MyHealthCheckBackend)
