Hi,

We set up our own healthchecks on Ubuntu 18.04 following the instructions in the Readme.

In Debug mode everything is working fine. But as soon as we switched debug=false, we got http 500 errors, which I think we solved by setting some missing properties and running "collectstatic" and "compress".

Now we a in a situation where it seems to basically work, but static resources are not being served (http 404 errors):

~/webapps/healthchecks$ ./manage.py runserver  
Performing system checks...

System check identified no issues (0 silenced).

As you can see, the REST calls work fine, its only resources that are not being served! if we switch back to debug mode, then it works fine again.

Our config file looks as follows:

SITE_ROOT = "https://health.xxx.com"
SITE_NAME = "XXX health"
DEFAULT_FROM_EMAIL = "monitoring@xxx.cloud"
DEBUG = False
REGISTRATION_OPEN = False
#ALLOWED_HOSTS = ["health.xxx.com","localhost"]
ALLOWED_HOSTS = ["*"]
CSRF_TRUSTED_ORIGINS = ["health.xxx.com","localhost"]

# Email
EMAIL_HOST = "xxx"
EMAIL_PORT = 587
EMAIL_HOST_USER = "xxxx"
EMAIL_HOST_PASSWORD = "xxx"
EMAIL_USE_TLS = True

PING_ENDPOINT = SITE_ROOT + "/ping/"
ADMINS = (  
            ('backoffice', 'backoffice@xxx.com'),
            )
SECRET_KEY = "xxx"
COMPRESS_OFFLINE = True
#STATIC_URL = 'static/'
#STATIC_ROOT = "/home/healthchecks/webapps/healthchecks/static/"

Our files on disk also look good to us:

healthchecks@dev:~/webapps/healthchecks$ ls -alph static/
total 24K
drwxrwxr-x  6 healthchecks healthchecks 4.0K Aug  3 13:56 ./

drwxrwxr-x  2 healthchecks healthchecks 4.0K Aug  3 13:30 js/

We cannot think of anything else to check, so perhaps your have at least a hint for us what to check for? Or is it perhaps even some bug?

Thanks a lot in advance,
Christian and Ales :-)

Hi Christian and Ales,

Django apps serve static files during development, but in production it is expected the static files will be served separately by a web server. See the Django docs here:

https://docs.djangoproject.com/en/3.2/howto/static-files/deployment/

Looking at the Healthchecks' README, there's no mention of serving static files, I'll look into improving the README. As a minimum, link to the above page.

If you plan to put nginx, apache, caddy or another web server in front of your Healthchecks instance, you can configure the web server to serve static files from ~/webapps/healthchecks/static-collected/.

Another option is to use whitenoise, but this requires changing settings.py. I'll look into adding whitenoise in the default configuration – it would be nice if static files worked out of the box.

Yes, that was it. It was not clear that the files are not served. Thanks!

For others reading this, we use NGinx to serve and now use the following configuration:

        location / {
                proxy_pass http://127.0.0.1:8000;
                proxy_set_header    Host             $http_host;
                proxy_set_header    X-Real-IP        $remote_addr;
                proxy_set_header    X-Forwarded-For  $proxy_add_x_forwarded_for;
        }

        location /static {
                alias /home/healthchecks/webapps/healthchecks/static-collected/;
        }

I plan to update README a bit, and look into using whitenoise. I'll keep this issue open until that's done so I don't forget.
