Root-cause problem, exception, and event notifications

diagnoses root-cause problems and detects (computes) events from status changes acquired in one of four ways:
  • Gathered from devices in the managed environment—SNMP and SOAP polling
  • Issued by devices in the managed environment—SNMP traps
  • Issued by
    IP Availability Manager
    —events, problems, and status attributes such as port status
  • Issued by
    —SNMP traps
    correlates status information to diagnose and report root-cause problems. Based on these problems, it also generates events to identify the impact on VoIP objects.
    also generates exceptions, or aggregate events, where an exception is a collection of events associated with a particular type of discovered object. An exception indicates one or more related failures or potential resource/capacity faults associated with a particular object. For example, when the ratio of active to total resource counts for MediaResourceAggregate exceeds a preset threshold value, a VoipCluster performance exception notification is generated to warn the operator of potential issues.
    generates exceptions for services, VoipCluster, CallManager, IPPhone, IPPhoneGroup, PortNetwork, VoiceMailApplication, and other object types. For any of these objects,
    generates an exception whenever any of the composite events for the object occur.
