Request flow log retrieval can include extracting one or more keywords from a natural language description of an action, the action being a system response to a user request submitted to a resource-provisioning system during a user session. Request flow log retrieval can also include determining a classification of the action based on a correlation value generated by a classifier model trained using machine learning to classify actions performed by the resource-provisioning system, the classification based on the one or more keywords. Additionally, request flow log retrieval can include automatically identifying a request flow associated with the action based on the classification of the action and returning at least one system log entry corresponding to the request flow.

Request flow log retrieval

Embodiments generally relate to selecting a service instance in a service infrastructure. In some embodiments, a method includes sending, by a service registry, a status request to each service instance of a plurality of service instances, where the service registry maintains a data store of performance information associated each of the service instances. The method further includes receiving, by the service registry, a plurality of status responses, where each status response is received from a respective service instance of the plurality service instances, and where each status response includes one or more performance characteristics. The method further includes ranking, by the service registry, the service instances based at least in part on the one or more performance characteristics. The method further includes performing, by the service registry, service lookups based on the ranking.

Selection of ranked service instances in a service infrastructure

Embodiments generally relate to finding a service in a service infrastructure. In some embodiments, a method includes receiving a service lookup request, where the service lookup request includes an application program interface (API) specification for a service to be invoked, where the API specification defines at least one target input parameter and at least one target output parameter. The method further includes searching for at least one service that has an API specification that corresponds to the API specification included in the service lookup request. The method further includes determining a sequence of services if no service is found that has an API specification that corresponds to the API specification included in the service lookup request, where services of the sequence of services include API specifications that, in combination, correspond to the API specification included in the service lookup request; and invoking the services of the sequence of services.
