Abstract:

A status notification method and facility is provided for use with a service chain processing a request for a service. The service chain can include multiple computer nodes, and the method includes dynamically creating the service chain for processing the request, and guaranteeing agreement, on at least two of the nodes of the service chain, about the status of the processing of the request. The method can also include saving detailed operational data logs in response to determining that a failure in processing the request has occurred. When a given node in the service chain determines that failure has occurred, agreement about the failure can be propagated throughout the service chain. Also, conditional logging of detailed operational data can minimize the amount of operational data transmitted over a network and saved to a data repository.
