Hello everyone, I will share with you the multicast KPI alarm monitoring case today.
Issue Description
A customer wants a suitable multicast KPI for the purpose of QoS alarm monitoring.
Alarm Information
To create a new QoS alarm for the purpose of KPI monitoring.
Handling Process
We need to study a suitable counter and threshold that can be used for the purpose of monitoring multi-cast KPI. This counter and threshold will somehow give an indicator if the multi-cast KPI performs abnormally or the multi-cast KPI services deteriorate.
Root Cause
Customer wants a suitable multi-cast KPI for the purpose of QoS alarm monitoring.
Solution
1) Firstly, we need to identify a suitable counter for Multi-Cast KPI. After doing some discussion and studies we propose below KPI:
eMBMS PDU Discarded Rate = [(L.MBMS.Disc.SYNC.PDU (None)/ L.MBMS.Rx.SYNC.PDU (None)]*100
2) Then, we collect the above KPI counter for the past 1 month on an hourly basis and see the distribution (at cell level) below and the pattern of distribution.
So we suggest using the threshold below for the eMBMS packet discarded rate.
3) After that, you may follow step-by-step of how to set the performance threshold alarm as below.
