Good Morning Claes:
To verify your key is being used, you can examine
the output of hgTracks. In your WEB browser,
use the 'view source' to see the text. At the
end you should see the google javascript code:
(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//
www.google-analytics.com/analytics.js','ga');
ga('create', 'UA-XXXXXXX-X', 'auto');
ga('require', 'displayfeatures');
ga('send', 'pageview');
You should see your key in that code. It may take a day or two
for the google analytics system to process your data and produce
a display.
You can also examine your Apache logs to find IP addresses and thus
a rough measure of 'users'. Use one of the Apache log analyzers
to produce a report from your logs. For example:
