Methods and system are provided for decomposing events from managed infrastructures. The system decomposes events from a managed infrastructure and includes a first engine that receives data from a managed infrastructure which includes managed infrastructure physical hardware. The infrastructure physical hardware supports the flow and processing of information. A second engine determines common characteristics of events and produces clusters of events relating to the failure of errors in the managed infrastructure. Membership in a cluster indicates a common factor of the events that is a failure or an actionable problem in the physical hardware managed infrastructure directed to support the flow and processing of information. Events are produced that relate to the managed infrastructure. The events are converted into words and subsets used to group the events that relate to failures or errors in the managed infrastructure, including the managed infrastructure physical hardware. The events have textural context. Semantic meaning is applied to the textual context of the events. A change to a managed infrastructure physical hardware component is made.
