From the analysis of some hard drawbacks faced with content service system today, such as heterogeneous, isolated content service systems and difficult integration, a novel Web Services-based Content Service Federation Platform (CSF-Platform), is introduced in this paper. In this infrastructure, we emphasize on heterogeneous service status monitoring issue; we propose a novel WSDM-based service status monitoring scheme in Content Service Federation Platform. And then we describe WSDM-based content service status monitoring architecture. We propose agent-based content service status collecting strategy, and analyze content service status monitoring process. As part of experiment work, we discuss Real-JADE based content service monitor system design and module implementation, including monitor agent work flow, supervisor agent work flow, and then analyze the experiment results. At last, from our research experiences and related survey, we analyze the prospective research direction and challenges in this field.
