MODELING OF INTERNET SERVICES.

摘要

The dependency of a computer service is modeled. The modeling hierarchically defines the relationships between the computer service and the hardware and software services which the computer service depends. These relationships may be contained in data structures defining a directed acyclic graph. The model also defines which measurements need to be taken to determine health and performance of the computerservice and the health and performance of all the computer services upon which the computer service depends. Software agents take these measurements may be deployed using the model to determine the meaurementlocations and functions. Data from measurement agents may be propagated up the model hierarchy. The model (200) may also be visualized by a geaphical interface to communicate the dependency and the health and status of the services upon which the nodeld service depends.
