Abstract: Methods, computer systems, and computer storage media are provided for identifying a source(s) of performance variability using relevant performance data. In embodiments, performance data indicating performance of a computing system is obtained. Such performance data is analyzed to identify relevant performance data including a representation of a differential graph that compares a first set of performance data associated with a first environment with a second set of performance data associated with second environment. Thereafter, a prompt is generated that includes the representation of the differential graph and a request for an identification of a source of performance variability associated with the relevant performance data. Based on the prompt, the source of performance variability associated with the relevant performance data may be identified via a large language model and provided for display.

Abstract: Methods, systems, and computer-readable media for real-time call tracing in a service-oriented system are disclosed. A request comprising a trace signature is received at a service in a service-oriented system. The trace signature comprises a representation of one or more upstream services in an upstream call path associated with the request. Based at least in part on the trace signature, the service determines one or more actions to perform with respect to the request.
