Anexia Monitoring

A Django app used to monitor updates for Django and all installed python packages in the running environment. It can be also used to check if the website is alive and working correctly.

Installation and configuration

Install the package by using pip

pip install django-anexia-monitoring

Add the app the settings installed apps

INSTALLED_APPS = [
  ...
  # Anexia monitor
  'anexia_monitoring',
  ...
]

In the projects settings.py add the access token configuration:

ANX_MONITORING_ACCESS_TOKEN = 'custom_access_token'

Add URL configuration for REST endpoint

from anexia_monitoring import urls as monitor_urls
...
urlpatterns = [
  ...
  # Anexia monitoring
  url(r'^', include(monitor_urls)),
  ...
]

Usage

The plugin registers some custom REST endpoints which can be used for monitoring. Make sure that the ANX_MONITORING_ACCESS_TOKEN is defined, since this is used for authorization. The endpoints will return a 401 HTTP_STATUS code if the token is not define or invalid, and a 200 status code otherwise.

Returns all a list with platform and module information.

Live monitoring

This endpoint can be used to verify if the application is alive and working correctly. It checks if the database connection is working and makes a query for users. It allows to register custom checks by using the dispatched monitor_up_check event.

URL: /anxapi/v1/up/?access_token=custom_access_token

Response headers:

Status Code: 200 OK
Access-Control-Allow-Origin: *
Access-Control-Allow-Credentials: true
Allow: GET
Content-Type: text/plain

Response body:

OK

Custom live monitoring event

This check can be defined into the app even subscribers

from django.dispatch import receiver
from anexia_monitoring.events import monitor_up_check

@receiver(monitor_up_check)
def list_of_complete_polls_handler(sender, **kwargs):
    """
    My custom is alive check
    """
    pass

Live monitoring settings

The User table is used in most Django applications and by default the up endpoint will make a test query to this table. If you don't need it you can disable it using the ANX_MONITORING_TEST_QUERY_USERS setting.

Similar most Django applications also use a database connection which the module tests for connection by default. If you don't need this you can deactivate it by providing the ANX_MONITORING_TEST_DB_CONNECTIONS setting.

ANX_MONITORING_TEST_QUERY_USERS = False
ANX_MONITORING_TEST_DB_CONNECTIONS = False
