摘要： A method, system, and computer program product are disclosed for merging search results. In one embodiment, the method comprises identifying a query, splitting the query into sub-queries, and calculating information content for each of the sub-queries. This method also comprises executing each of the sub-queries to obtain a plurality of search results, and combining the search results based on the information content calculated for the sub-queries. In an embodiment, the execution of each of the sub-queries includes identifying a multitude of search results for at least one of the sub-queries; and the combining includes grouping said multitude of search results into a plurality of clusters, and computing a relevance score for each of said clusters. In the embodiment the combining further includes merging the clusters based on the relevance scores computed for the clusters as well as the information content calculated for the sub-queries.

摘要： A system, method and computer program product for detecting and reacting to a network discrepancy within a data center network environment. The method comprises monitoring network traffic between a first computer configured as a first hypervisor inter-networked within the data center network environment and a second computer inter-networked within the data center network environment in order to detect a presence of a predetermined condition representing a presence of the network discrepancy in the data center network environment between a recorded state of the data center network environment and an observed state of the data center network environment. The monitoring includes determining the observed state of the data center network environment using one of: polling, event-based or a combination thereof. The method also comprises rectifying, upon the detection of the presence of the predetermined condition, an effect associated with the presence of the predetermined condition in the data center network environment.

摘要： A method, an apparatus and an article of manufacture for detecting an event storm in a networked environment. The method includes receiving a plurality of events via a plurality of probes in a networked environment, each of the plurality of probes monitoring a monitored information technology (IT) element, aggregating the plurality of events received into an event set, and correlating the plurality of events in the event set to determine whether the plurality of events are part of an event storm by determining if the plurality of events in the event set meet one or more event storm criteria.

摘要： A mechanism is provided for handling incidents occurring in a managed environment. An incident is detected in a resource in the managed environment. A set of incident handling actions are identified based on incident handling rules for an incident type of the incident. From the set of incident handling actions, one incident handling action is identified to be executed based on a set of impact indicators associated with the set of incident handling rules. The identified incident handling action is then executed to address the failure of the resource.

摘要： A scalable and fault tolerant finite state machine engine, for example, for use in an automated incident management system, logs or records data in persistent storage at different points or levels during various internal processing of an event associated with an information technology element, and action taken associated with the event, by executing a finite state machine instance that encodes policies for handling incidents on such types of information technology elements. In the event that the finite state machine engine is shutdown during processing, the finite state machine engine is able to pick up from where it left off when it was shutdown, for each abnormally terminated finite state machine instance, by using the data logged in the persistent storage and determining a point of processing from where it should continue its execution.
