METHOD FOR MONITORING A COMPUTATIONAL SYSTEM

A computer-implemented method (300) of monitoring a computational system (100), said computational system comprising a plurality of interoperating computing components (210) for performing computational operations thereby to provide a computational service to a user (120), wherein said computational system comprises a plurality of performance requirements based on at least one performance attribute, the method comprising the steps of: selecting a performance attribute associated with a performance requirement of the computational system (310); identifying a set of computing components from the plurality of computing components, wherein each of the computing components in the set perform operations affecting the selected performance attribute (320); determining a mapping of relationships for the computing components in the identified set in relation to the selected performance attribute; retrieving a performance status of a computing component in the identified set (320); and in dependence on said determined mapping and said retrieved performance status, calculating a probability of the identified set complying with the performance requirement for the selected performance attribute (340).
