RIC metrics list

[fllay]

Now only three metrics are exposed. May I ask what are all metrics for E2SM_KPM? Is there any standard about metrics for E2SM_KPM? Or it depends on gNB implementation. For example, will PRB and numer of UEs be implemented? Are there mandatory metrics that have to implement? I tried to find any information about this but I can find only few. Thank you.

Hi,
The metrics are listed in two different places:

• 3GPP TS 28.552
• O-RAN.WG3.E2SM-KPM-R003-v3.00
  We will be expanding the list of supported metrics in later releases according to demand, the three metrics currently implemented were meant to serve as an example for anyone who wished to implement their own metrics.

If you have specific metrics from the above documents you are interested in, please share them here and we will take them into consideration!

Thanks,
Justin

Hello @yagoda, are there any instructions or guidelines/tutorials on how would one go about implementing their own metrics?
Thank you !

Thank you for clarification. I am interested in Section 5.1.1, Performance measurements valid for all gNB deployment scenarios, of 3GPP TS 28.552. Especially, radio resource metrics of Section 5.1.1. It would be nice if there is a document about how to implement our own metrics.

Currently, we do not have such guidelines, but you can have a look and check how the currently supported metrics are implemented. Basically, e2sm_kpm_du_meas_provider_impl is an objects that translates the internal gnb metrics into the E2 metrics.
