Add Application Insights to Ghost on Azure

If you deployed Ghost on Azure with the default settings, like in my blogpost, you get an instance of Application Insights with it. Unfortunately, it will only capture generic events and not the more detailed page views. Time to fix this!

1. In the Azure Portal, get your Application Insights instrumentation key
2. In your Ghost admin panel, open the Code injection page
3. Put the following script in the Blog Header field. Remember to add your own instrumentation key!

<!-- 
To collect user behavior analytics tools about your application, 
insert the following script into each page you want to track.
Place this code immediately before the closing </head> tag,
and before any other scripts. Your first data will appear 
automatically in just a few seconds.

<script type="text/javascript">
  var appInsights=window.appInsights||function(config){
    function i(config){t[config]=function(){var i=arguments;t.queue.push(function(){t[config].apply(t,i)})}}var t={config:config},u=document,e=window,o="script",s="AuthenticatedUserContext",h="start",c="stop",l="Track",a=l+"Event",v=l+"Page",y=u.createElement(o),r,f;y.src=config.url||"https://az416426.vo.msecnd.net/scripts/a/ai.0.js";u.getElementsByTagName(o)[0].parentNode.appendChild(y);try{t.cookie=u.cookie}catch(p){}for(t.queue=[],t.version="1.0",r=["Event","Exception","Metric","PageView","Trace","Dependency"];r.length;)i("track"+r.pop());return i("set"+s),i("clear"+s),i(h+a),i(c+a),i(h+v),i(c+v),i("flush"),config.disableExceptionTracking||(r="onerror",i("_"+r),f=e[r],e[r]=function(config,i,u,e,o){var s=f&&f(config,i,u,e,o);return s!==!0&&t["_"+r](config,i,u,e,o),s}),t
    }({
        instrumentationKey:""
    });

    window.appInsights=appInsights;
    appInsights.trackPageView();
