Hi Ho-Sung,
this is a typo in the documentation, the property is called
servicesTypesForIndependentServices=HTTP
Further you may check whether you want to have a Hyperic server modeled as a resource or a Hyperic service. If it is a service, you need to specify the parent server as well. E.g.
serverTypesForIndependentServices=MyRuntime
servicesTypesForIndependentServices=MyApp
After changing hyperic.properties you need to restart the collector service: service vmware-vcops restart collector
Regards,
Gregor
