Java - Weblogic - JMX: request available free memory on all servers

Question

Once I get a JMX connection to my main web server, how can I get the current free memory for each of my registered servers?

I requested DomainRuntimeServiceMBean and listed all its attributes and operations, but I can not find anything that is related to memory.

(I am using weblogic 9.x)
