Solution 2211652.1 : Alarms TKPIC02082 And 02083 Are Not Clearing And Are Reporting On Incorrect Usage Values

Applies to:

Oracle Communications Performance Intelligence Center (PIC) Software - Version 9.0.0 and later
Information in this document applies to any platform.

Symptoms

The Low threshold and high threshold alarms for SLOR (Signaling Link Occupancy Rate) is not always well understood.

Example: SLOR thresholds have been set as follows: Low threshold at 40%, High threshold at 80%.

The user may think that the system should generate an alarm when the Occupancy rate falls under 40 % or overpass 80 %. But this is wrong...

Changes

Cause

Low and High threshold alarm will be triggered when the occupancy will overpass the value set.

When "Low" threshold value is overpass, PIC generates a "Minor" alarm.

When "High" threshold value is overpass, PIC generates a "Major" alarm.

HoldOn value avoid PIC to clear/generate useless flow of alarms if the difference is lower than the indicated percentage: when a threshold is reached, PIC generates an alarm. This alarm will be cleared only when the SLOR will have the value: Threshold - HoldOn (e.g. Low =40%, and HoldOn=10%, alarm will be cleared when the traffic will be under 30%).

Explain how SLOR alarms are managed

Solution

Set correctly the various thresholds and the HoldOn value to manage easily and correctly such alarms.
