1. A method for automated detection of a real IT system problem, the method comprising: obtaining monitor measurements of metrics associated with activities of a plurality of configuration items of the IT system; detecting anomalies in the monitor measurements; identifying at least two anomalies as concurrent anomalies that occur within a predetermined period of time; determining that the concurrent anomalies correspond to configuration items, of the plurality of configuration items, wherein the configuration items are topologically linked; grouping the concurrent anomalies to be regarded as a single system anomaly; calculating a significance score for the system anomaly; and determining that the system anomaly relates to a real system problem based on the calculated significance score.
