Why my cluster memory is less even though physical memory is more..?

We have 2-node cluster(1 master 4 CPU,16 GB RAM + 1 data node 8 CPU,30 GB RAM). However in Ambari console, I could be able to see the Total cluster memory is 22 GB only. Is there a way to allocate more cluster memory(around 36GB ) out of 46 GB physical memory we have together from master + data node. Morever, the number of containers are only 5 whereas the available Vcores are 8 already. I have attached the screenshot for your reference. Please suggest a way to improve the cluster resource utilization. Thank you in advance.

Ideally Ambari should show your total RAM and CPU information, until if you have any issues with Ambari agent.

Can you provide free -m output from your both the nodes and add scree shots of ambari cluster information.??
