An event clustering system includes a processor. An extraction engine is in communication with an infrastructure. The extraction engine receives data from the infrastructure. A signalizer engine includes one or more of an NMF engine, a k-means clustering engine and a topology proximity engine. The signalizer engine determines one or more common steps from events and produces clusters relating to the alerts and or events. In response to production of the clusters one or more physical changes are made in a managed infrastructure hardware. Multi-systems interact with each other.
