BASELINING SERVICE-TAGGED DATA FROM SUBSERVICES OF A SERVICE FOR IMPROVED SERVICE ASSURANCE

A method comprises configuring a service as a collection of subservices on network devices of a network, and decomposing a definition of the service into a subservice dependency graph that indicates the subservices and dependencies between the subservices that implement the service. The method further comprises, based on the subservice dependency graph, configuring a subservice among the subservices to record and report a subservice metric as an indicator of subservice performance. The method further comprises determining a rate at which to obtain values of the subservice metric from the subservice, determining a confidence interval for the values of the subservice metric, and obtaining the values of the subservice metric from the subservice at the rate, to produce values for monitoring the subservice. The method also includes determining whether at least one of the values for monitoring the subservice is within the confidence interval.
