django-healthpoint 0.4.1

Easily create an endpoint for health checks

Framework for adding an endpoint for health checks to your project.

Source code

http://github.com/pennersr/django-healthpoint

Quickstart

Install the app:

# settings.py
INSTALLED_APPS = [
    ...
    'healthpoint'
]

# If specified, this user is able to see the details for each
# individual check in the endpoint.
HEALTHPOINT_BASICAUTH_USERNAME = 'john'
HEALTHPOINT_BASICAUTH_PASSWORD = 'doe'

# urls.py
urlpatterns = [
    ...
    url(r'^', include('healthpoint.urls')),
]

Add a module named health.py to any of your apps. For example:

from datetime import timedelta

from django.contrib.auth.models import User
from django.utils import timezone

from healthpoint.decorators import health_check


@health_check
def user_signup():
    last_user = User.objects.last()
    time_since_last_signup = timezone.now() - last_user.date_joined
    # Return True/False, throw an exception, or return a tuple with a
    # detail message.
    return (
        time_since_last_signup <= timedelta(days=1),
        "last signup was: {}".format(last_user.date_joined))

The health checks can be accessed via the /health/ endpoint:

• It executes all health checks, and reports status 200 if all checks succeed, status 500 otherwise.

• If a staff user is logged in, the endpoint reports the result for each individual check:

  {
   "success": {},
   "error": {
     "myproject.myapp.health.user_signup": "Last signup was: 2017-10-29 08:45:51"
   }
  }

• To provide more detail on the result, the @health_check can return a tuple (success:bool, detail:str). The detail message will be listed in the result.
