Ok, tried for quite a while today to setup the demo using psutil. Keep getting an error on the browser side as follows:

TypeError: window.swampdragon_settings is undefined 
ReferenceError: swampdragon is not defined

Tried to hunt this down but having a hardtime finding where the issues are coming from. Pycharm is telling me that swampdragon_host is unresolved in swampdragon.js.

function getHost() {
    var host = window.swampdragon_host,
        endpoint = window.swampdragon_settings.endpoint;

    if (endpoint.indexOf('/') != 0) {
        endpoint = '/' + endpoint
    }

    host = host + endpoint;
    return host;
}

Any ideas?

Do you have the settings.js file included in your page?

I followed this tutorial. Did not see a settings.js included anywhere in this.

Disclaimer: I am new to this so I could be over looking something completely, but I have followed the tutorial step by step and not having any success.

In the adding template part of the tutorial you see the following code in the body of the page {% swampdragon_settings %}

If you're using django templates you should make sure that that line is there. If you're using something else such as a standalone front-end app you should include a link to the settings.js file manually like such
<script src="http://address_of_sd_host:9000/settings.js></script>

</head>
<body>

<!-- SwampDragon -->
{% swampdragon_settings %}
<script type="text/javascript" src="{% static 'swampdragon/js/dist/swampdragon.min.js' %}"></script>

<!-- Monitor -->
<script type="text/javascript" src="{% static 'monitor.js' %}"></script>

Welp solved my issue. Seems to be a combination of the following.

  1. Needed to tun manage.py runsd
  2. Needed to change some configurations regarding static files in settings.py

replaced

STATIC_ROOT = os.path.join(BASE_DIR, 'static')
STATIC_URL = '/static/'

with

STATIC_ROOT = ''

STATIC_URL = '/static/'

STATICFILES_DIRS = ( os.path.join('static'), )
