Referring additionally now to FIGS. 2A-2E, the construction by constructor 112 of invocation matrices for three illustrative process paths are described, as are the construction of a network matrix and corresponding relative frequency matrix. FIG. 2A depicts an invocation matrix corresponding to process 200, the above-described process whose process path can be represented vectorially as (start, 1, 3, 1, 2, 5, 6, end). Process 200 begins with invocation of microservice MS1, which invokes microservice MS3, which in turn invokes MS1. After MS1 again executes, the microservice invokes MS2, which executes and invokes microservice MS5. MS5 executes and then invokes microservice MS6, which upon completion ends process 200.
