Abstract

Disclosed is an extension to the Event Relationship Network (ERN) syntax which specifies location of event correlation within a hierarchically structured event management architecture. This syntactical extension applies the attribute of correlation tier number(s) to the event and/or ERN subnet connector objects within the ERN, thus indicating at which management tier the event relationship applies. Prior to the invention described in this disclosure the ERN protocol applied to single-tier event management architectures within which systems, application, or networking events are communicated directly to a single event management point as represented in Fig. 1 (left). Applying the attribute of tier number(s) to the connector objects enables the application of Event Relationship Networks to the multi-tier management environments represented in Fig.1 (right).

Multi-tier Management Extensions for Event Relationship Networks

Disclosed is an extension to the Event Relationship Network (ERN) syntax which specifies location of event correlation within a hierarchically structured event management architecture. This syntactical extension applies the attribute of correlation tier number(s) to the event and/or ERN subnet connector objects within the ERN, thus indicating at which management tier the event relationship applies.

Prior to the invention described in this disclosure the ERN protocol applied to single-tier event management architectures within which systems, application, or networking events are communicated directly to a single event management point as represented in Fig. 1 (left). Applying the attribute of tier number(s) to the connector objects enables the application of Event Relationship Networks to the multi-tier management environments represented in Fig.1 (right).

Prior to the invention described in this disclosure, ERNs documented event relationships only. Sufficient relationship information is provided within these ERNs to describe the logic of event correlation. An example of the base ERN is presented in Fig. 2.
