What 'memory total' actually means in yarn web UI

What does memory total represent in hadoop yarn web interface ?

Is it my total cluster capacity or is it something else? It is representing 48 GB under "memory total" for my cluster having 6 nodes. And also each node is showing 8GB only in available memory. Is it correct ?

The answer is simple memory total is cluster capacity. The rest can be explained using simple algebra. 

 6 x 8 = 48

In a generic way :

memory_total = number_of_nodes x memory_of_each_node
