Google Analytics - How to get the client_id (anonymous client id) sent with Measurement Protocol

问题

we are seding requests like this throught the google analytics measurement protocol to track user interaction there. For us its important to be to link a interaction to a specific user so we where happy to be able to set the "cid" attribute of the protocol.

my problem is that I cannot find this Client ID somewhere inside the reports of google analytics. Even when customizing the reports I cannot find a Dimension which allows me to display this information.

http://www.google-analytics.com/collect?
 v=1             // Version.
 &tid=UA-XXXX-Y  // Tracking ID / Property ID.
 &cid=555        // Anonymous Client ID.

 &t=event        // Event hit type
 &ec=video       // Event Category. Required.
 &ea=play        // Event Action. Required.
 &cm18=8000
 &cd6=crocodile

Do you have an idea of how the cid could be found there?

回答1:

Client id is assigned to a user(client) viewing your site by google analytics. Here is an example of how you can get the client id if you're using jQuery.

$(document).ready(function() {
  setGaClientId();
});

var setGaClientId = function(){
  if(typeof(ga) != 'undefined'){
    ga(function(tracker) {
      console.log(tracker.get('clientId')); //actually do something here
    });
  }
}
