Abstract: Web based services, or E-services are increasingly beginning to cooperate to perform complex tasks. This has resulted in transactions that although begin and end at an e-service have parts of them executed on other cooperating e-services. Because of their federated nature and varied implementation, it is difficult to perform end-to-end management of such transactions that span multiple e-services. The problem would be compounded by the increasing trend of dynamic composition of e-services. Application Response Measurement is a standard for measuring application responses that originate at a client and involve multiple servers. We extend ARM to the e-services world to perform end-to-end transaction management. In doing so we enable multi-dimensional correlation-a local correlation as well as correlation spanning multiple e-services.
