Description

Tried to install a 3-node cluster using Vagrant.
Got a warning saying that I don't have enough RAM.
Showing these warnings are OK and useful, but the message doesn't seem right.

Perhaps change to:

Not enough physical RAM on c6403.ambari.apache.org.
At least 5632MB is recommended to run Ambari Metrics Collector.

or something like that. Actually, the RAM shown doesn't seem like what is required by Ambari Metrics Collector, but rather the total amount needed to run all services on the host based on component assignments (when I tried, it was saying I need 12GB to run all components). If that's the check, then this warning should not be shown specifically against AMS.
