Alarm correlation

Overview

A correlated alarm indicates that a fault on an object is caused by a fault on another object. For example, if a port goes down, an alarm is generated for the port, and correlated alarms are generated for services that rely on the port. To ignore correlated alarms in the JMS stream, filter out alarms where ALA_isCorr is true.

Note: The ALA_isCorr property is not included in all events. See Alarm-specific header properties in JMS message filtering for information.

See “Correlated alarms” in the NSP NFM-P Classic Management User Guide for more information about correlated alarms.
