1. A method for correlating performance events in a data processing system, the method comprising:
- receiving a first event at a first device of the data processing system;
receiving a second event at a second device of the data processing system, wherein the first event comprises a first alarm and the second event comprises a second alarm;
identifying a type of a connection between the first device and the second device to form an identified type of connection; and
determining a relationship between the first event and the second event based on the identified type of connection between the first device and the second device, wherein the identified type of the connection comprises a direct wire connection between a first port of the first device and a second port of the second device, wherein the first alarm indicates that egress utilization is high for packets transmitted on the first port, wherein the second alarm indicates that ingress utilization is high for packets received on the second port, and wherein the determined relationship comprises that the first and second alarms each indicate a high egress utilization on the first port.

Abstract
Method, apparatus and computer program product for correlating performance events in a data processing system. A first event is received at one of a first device and a second device of the data processing system, and a second event is received at one of the first device and the second device. A type of a connection between the first device and the second device is identified to form an identified type of connection, and a relationship between the first event and the second event is determined based on the identified type of connection between the first device and the second device.
