title: Is it possible to track requests within the GCP load balancer similar to AWS ELB?
body: <p>I noted that within AWS you can trace requests at the Load Balancer which is useful for unique identification. Within Google Cloud Platform it appears that we are limited to several variables which doesn't provide a unique ID.</p>
  
  <p>Is anyone using GCP and implementing a unique ID? </p>
