Abstract

Embodiments of the present invention provide a method, system and computer program product for cross-cutting event correlation in an enterprise computing monitoring and management system. An enterprise computing monitoring and management system can include a hierarchy of nodes, where several of the nodes are each coupled to a corresponding embedded correlation engine and an event bus. The system further can include a root node among the nodes. The root node can be coupled to the event bus and to centralized correlation logic programmed to identify a high correspondence between events from a particular event source among the nodes and a particular set of correlation rules in that correlation engine. The identification of such correspondence can be used to move to the set of correlation rules to an embedded correlation engine closer to the particular event source.

Claims

1. An enterprise computing monitoring and management data processing system comprising:

a hierarchy of nodes, each of a plurality of the nodes being coupled to a corresponding embedded correlation engine and an event bus;

a root node among the nodes, the root node being coupled to the event bus and to cross-cutting correlation logic, the cross-cutting correlation logic comprising program code enabled to identify a high frequency of events from a particular event source among the nodes and to move a corresponding correlation rule to an embedded correlation engine closer to the particular event source.

2. The system of claim 1, wherein the nodes comprise:

at least one gateway; and

,

a plurality of endpoints coupled to the at least one gateway.

3. The system of claim 1, further comprising a cross-cutting correlation rules run-time structure configured for access by a correlation engine, the run-time structure representation comprising a plurality of correlation rules, each of the correlation rules referencing at least one event set, the at least one event set referencing at least one event source for an event and a frequency of occurrence of the event for the event source.

4. The system of claim 1, wherein the program code of the cross-cutting correlation logic is further enabled to monitor a set of attributes for each of the events handled in different embedded correlation engines in the hierarchy, to identify patterns among the events, and to trigger actions upon identifying the patterns.

5. The system of claim 4, wherein the attribute source comprises a combination with other event attributes to determine an affinity between events from a given event source using a cross-cutting correlation rule in a correlation engine.

6. The system of claim 5, wherein at least one of the patterns matches events demonstrating particular event attributes arising from a particular event source with a particular frequency.

7. The system of claim 6, wherein the program code of the cross-cutting correlation logic is yet further enabled to query a database of correlation rules using an identified one of the patterns to locate a correlation rule enabled to match the attributes of the identified patterns, and to copy the located correlation rule to a correlation engine for an event source for the identified patterns.

8. A cross-cutting event correlation method comprising:

receiving events originating from a plurality of different event sources;

detecting a high frequency of occurrence of a received event in a particular event source; and

,
