Method for monitoring a computational system

Abstract

A computer-implemented method () of monitoring a computational system (), said computational system comprising a plurality of interoperating computing components () for performing computational operations thereby to provide a computational service to a user (), 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 (); 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 (); 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 (); 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 ().
