Custom instrumentation to record strict, direct funnels within New Relic Insights

directFunnelScript.js

//instantiate globally
//below is the global array where we'll record the last 6 steps
window.NewRelicDirectFunnelArray = ["", "", "", "", "", ""];
//and the function we'll use to manage the data structure
window.NewRelicDirectFunnelFunction = function(pageActionName){
  //capture a delimited string containing the last 6 pageActions since the initial pageload
  var previousSixPageActionsString = window.NewRelicDirectFunnelArray.join("||");
  //dequeue the oldest pageAction value out of the queue
  window.NewRelicDirectFunnelArray.shift();
  //push the newest pageAction value into the queue
  window.NewRelicDirectFunnelArray.push(pageActionName);
  //return the delimited pageAction path value
  return { "previousPageActionPath" : previousSixPageActionsString };
};

//
//

//then, you may instantiate within your code similar to this
/*

newrelic.addPageAction( pageActionName , window.NewRelicDirectFunnelFunction(pageActionName) );
