Abstract: A head-end node in a Segment Routing network includes circuitry configured to detect a failure of a Segment Routing policy, set an eligibility flag for the candidate path associated with the Segment Routing policy to false, and, if one or more other candidate paths exist for the Segment Routing policy, switch to another candidate path of the one or more other candidate paths considering corresponding eligibility flags for the one or more other candidate paths. The eligibility flag and the corresponding eligibility flags are maintained by the head-end node for the candidate path and the one or more other candidate paths such that the head-end node selects a path based thereon.

Abstract: A method and system is disclosed for monitoring an operation of a distributed data processing system. The system can include a plurality of applications running on a plurality of host processors and communicating with one another, such as through a message passing technique. The method includes steps executed in individual ones of the plurality of applications, of (a) examining individual ones of generated API calls to determine if a particular API call meets predetermined API call criteria; (b) if a particular API call meets the predetermined API call criteria, storing all or a portion of the content of the API call as a stored event; (c) processing a plurality of the stored events to identify logically correlated events, such as those associated with a business transaction; and (d) displaying all or a portion of the stored API call content data for the logically correlated events.
