A method and system for monitoring availability data of a system management (SM) environment. A connection configuration associated with the SM environment is retrieved from a central repository, wherein the SM environment is coupled to a SM portal server that includes the central repository, and wherein the SM environment includes one or more terminal systems. In response to determining that the retrieved connection configuration properly establishes communication between the SM portal server and the SM environment, availability data pertaining to availability of resources at endpoints of the one or more terminal systems is collected. The collected availability data recorded in the central repository.
