ELB Metrics

Once you have enabled ELB, you can use Cloud Eye to view the status of load balancers or listeners added to enhanced load balancers without installing any plug-in. Table 1 lists the metrics of classic load balancers, and Table 2 lists the metrics of enhanced load balancers and enhanced load balancer listeners.
