A service is a common service is the requirement of that to get the HOST_COMPONENT metrics of this service?

Hi,    We can not get the HOST_COMPONENT metrics of a custome service in AMBARI 
SERVICE STACKS, by AMS api, right?    Is it appropriate to make a custom 
service become a common service of ambari?    Waiting for reply.
