Ambari Makes use of the JMX APIs provided by the individual components to get the Heap details like:

http://$NAMENODE_HOST:50070/jmx?qry=Hadoop:service=NameNode,name=JvmMetrics

.

Similarly HBase memory details are retrieved using the following MBean. http://$HBASE:16010/jmx

Hadoop:service=HBase,name=JvmMetrics

.
