Attribute value change event elements

An attribute value change alarm indicates changes to a particular problem alarm that the probe received earlier. Based on the indicated changes, the probe generates a standard set of elements for each attribute value change event that it receives.

The probe performs the following if the attribute value change alarm indicates that the severity field is updated with a value other than cleared in Attribute4:

  • Deduplicates the problem alarm.
  • Updates severity of the problem alarm with the latest value.
  • Increments the count of the problem alarm by 1.

The probe performs the following if the attribute value change alarm indicates that the severity field is updated with a cleared value in Attribute4:

  • Makes the attribute value change alarm as a new resolution alarm in the event list. This action is performed as per the Netcool/OMNIbus generic clear standards.
  • Clears both the problem alarm and the resolution alarm.

It is possible that the probe may receive another attribute value change alarm before the problem alarm was cleared. If this new attribute value change alarm indicates that the severity field is updated with a value other than cleared in Attribute4, then the probe performs the following:

  • Deduplicates the problem alarm.
  • Updates severity of the problem alarm with the latest value.
  • Increments the count of the problem alarm by 1.

It is The probe performs the following if the attribute value change alarm indicates that attributes other than the severity field are updated in Attribute4:

  • Deduplicates the problem alarm.
  • Keeps the severity field with its current value.
  • Increments the count of the problem alarm by 1.

The following table describes the elements that are generated for attribute value change events.
