This paper proposes a novel approach to service management and monitoring on the basis of service collaboration relations that can be extracted from service composition history. An undirected and weighted service collaboration network is constructed therefore. On the network, two abstractions are defined: service centrality, which measures a service's collaboration capability comparing to other services for a long period, and service activeness, which measures the frequency of a service's collaboration with others for a short period. The capability of service management among Open APIs is investigated and demonstrated. Experimental data are collected from Programmable Web with the period from 2005-9-14 to 2009-9-21. Experiments show that the defined metrics can properly reflect the service properties.
