Configuration
You can configure the app using the dict STATUSBOARD in settings.py:
from django.contrib.staticfiles.templatetags.staticfiles import static
# for Django >= 3.0: from django.templatetags.static import static
STATUSBOARD = {
"INCIDENT_DAYS_IN_INDEX": 7,
"OPEN_INCIDENT_IN_INDEX": True,
"AUTO_REFRESH_INDEX_SECONDS": 0,
"FAVICON_DEFAULT": static('statusboard/images/statusboard-icon-default.png'),
"FAVICON_INDEX_DICT": {
0: static('statusboard/images/statusboard-icon-operational.png'),
1: static('statusboard/images/statusboard-icon-performance.png'),
2: static('statusboard/images/statusboard-icon-partial.png'),
3: static('statusboard/images/statusboard-icon-major.png'),
},
}
INCIDENT_DAYS_IN_INDEX: number of days to show in index (1 = today).
OPEN_INCIDENT_IN_INDEX: show not fixed incidents in index, whether or not the incident is older than INCIDENT_DAYS_IN_INDEX.
AUTO_REFRESH_INDEX_SECONDS: auto refresh home page every N seconds (0 = disabled).
FAVICON_DEFAULT: default favicon.
FAVICON_INDEX_DICT: favicon for index, based on the worst status (default: FAVICON_DEFAULT). The keys (0, 1, 2, 3) are the status values (see SERVICE_STATUSES in statusboard/models.py).
Customize pages
The following blocks are customizable in statusboard/base.html:
title: title of the page
branding: branding in fixed navbar
bootstrap_theme: bootstrap theme
header: header of the page
userlinks: links in the header
footer: footer div
style: CSS files
script: JavaScript files
Example: change branding and title
In Django >= 1.9, the templates can be extended recursively (see https://docs.djangoproject.com/en/1.9/releases/1.9/#templates).
Create a statusboard/base.html in one of your templates dir:
{% extends `statusboard/base.html %} {% block title %} ACME, Inc. {% endblock %} {% block branding %} <a class="navbar-brand" href="{% url 'statusboard:index' %}">ACME status</a> {% endblock %}
Notifications
django-statusboard doesn’t provide an out-of-the-box notification system, but it’s easy to implement using django signals.
Moreover, django-statusboard tracks the previous status of a service (Service._status).
from django.dispatch import receiver
from django.db.models.signals import post_save
from django.core.mail import mail_admins
from statusboard import Service
@receiver(post_save, sender=Service)
def notify_service_update(sender, instance, **kwargs):
# Send an email to admins if the service is getting worse, otherwise do nothing.
if instance.status > instance._status:
mail_admins("Alert", "Service {} is {}".format(instance.name, instance.get_status_display()))
REST API
django-statusboard comes with a set of REST API to manage its models, based on Django REST Framework ModelViewSet.
