An event clustering system is provided. An extraction engine is in communication with an infrastructure. The extraction engine in operation receives data from the infrastructure and produces events. An alert engine receives the events and creates alerts mapped into a matrix, M. A sigalizer engine includes one or more of an NMF engine, a k-means clustering engine and a topology proximity engine. The sigalizer engine determines one or more common steps from events and produces clusters relating to the alerts and or events. A data extraction device is configured to be coupled to the event clustering system.
